Chinese listed companies have a two-tier governance structure that comprises a supervisory board/committee and the board of directors. However, as there is no hierarchical relationship between them, the two boards are independent. This is different from the governance mechanism in Continental Europe in which the SB appoints the directors of the management board; in this sense, the Chinese two-tier governance structure is unique. We investigate the impact of governance characteristics and ownership structure on gender diversity of both the BoD and (...) the SB for a sample of 892 Chinese Initial Public Offerings floated in both the Shanghai and Shenzhen Stock Exchanges. We find that the average proportion of female directors and female SB members on the BoD and the SB are 10 and 22 %, respectively. Using both static and dynamic panel data methods, we find that there is no significant impact of board structure on gender diversity in China. However, we find a positive and significant relationship between SB size and gender diversity. We also find that the higher the state ownership, the lower the female representation on both boards. Finally, our findings show that there is a bi-directional relationship between financial performance and the proportion of female directors sitting on the BoD. (shrink)

This paper is concerned with the estimation of the Weibull generalized exponential distribution parameters based on the adaptive Type-II progressive censored sample. Maximum likelihood estimation, maximum product spacing, and Bayesian estimation based on Markov chain Monte Carlo methods have been determined to find the best estimation method. The Monte Carlo simulation is used to compare the three methods of estimation based on the ATIIP-censored sample, and also, we made a bootstrap confidence interval estimation. We will analyze data related to the (...) distribution about single carbon fiber and electrical data as real data cases to show how the schemes work in practice. (shrink)

This article deals with the social production of knowledge in the exact sciences. After defining the term ?exact science?, it delineates the broad dynamic of its history. It, then, offers a socio-economic historical explanation of why the production of knowledge has become a major industry, if not the largest industry, in the last hundred years. The article concludes by drawing a detailed blueprint of the components, mechanisms, and specificities of the knowledge industry.

Relativity was Einstein’s main research programme and scientific project. It was an open-ended programme that developed throughout Einstein’s scientific career, giving rise to special relativity (SR), general relativity (GR), and unified field theory. In this article, we want to uncover the methodological logic of the Einsteinian programme, which animated the whole programme and its development, and as it was revealed in SR, GR, and unified field theory. We aver that the same methodological logic animated all these theories as Einstein’s work (...) progressed. Each of these theories contributed towards constructing Einstein’s ambitious programme. This article is not a contribution to the history of relativity, but, rather, it utilises our knowledge of this history to uncover the methodological logic of the relativity programme and its development. This logic is latent in the historical narrative but is not identical to it. We hope to show that the Einsteinian relativity project is still relevant today as a theoretical scheme, despite its failures and despite quantum mechanics. (shrink)

In several studies, knowledge is witnessed as one of the foundations of long-term competitive edge and is also a basic source of new product development performance. The aim of this study is to investigate the role of knowledge management capabilities in new product development performance with the mediating role of organizational agility. Additionally, this study also intends to examine the moderating role of business model innovation on the relationship of KMC with organizational agility. This study was conducted on the Chinese (...) automobile sector, and the NPD project managers, supervisors, and engineers of the sector were respondents of this study. A survey questionnaire was used to collect the data from 201 respondents, and data were analyzed using the Smart PLS 3 software. The findings of this research, although limited to the automobile industries, indicate that knowledge sharing and knowledge application have significant and positive effects on the development of new products. Organizational agility significantly mediates the relationship of KMC with NPD. The results found that business model innovation has a significant moderating role in the relationship between KMC and organizational agility. Moreover, the results of this study will assist the managers in developing a modern competitive business environment by implicating KMC in the process of NPD. Lastly, organizations may improve the sustainability of their product and their overall performance by using organizational agility and modern ways of value delivery. (shrink)

Weight systems on chord diagrams play a central role in knot theory and Chern-Simons theory; and more recently in stringy quantum gravity. We highlight that the noncommutative algebra of horizontal chord diagrams is canonically a star-algebra, and ask which weight systems are positive with respect to this structure; hence we ask: Which weight systems are quantum states, if horizontal chord diagrams are quantum observables? We observe that the fundamental gl(n)-weight systems on horizontal chord diagrams with N strands may be identified (...) with the Cayley distance kernel at inverse temperature beta=ln(n) on the symmetric group on N elements. In contrast to related kernels like the Mallows kernel, the positivity of the Cayley distance kernel had remained open. We characterize its phases of indefinite, semi-definite and definite positivity, in dependence of the inverse temperature beta; and we prove that the Cayley distance kernel is positive (semi-)definite at beta=ln(n) for all n=1,2,3,... In particular, this proves that all fundamental gl(n)-weight systems are quantum states, and hence so are all their convex combinations. We close with briefly recalling how, under our "Hypothesis H", this result impacts on the identification of bound states of multiple M5-branes. (shrink)

Religious Reflection Scales yield cross-cultural data suggesting that religious traditions have potentials to integrate intellect with faith. This investigation extended analysis of that possibility to Sunni Muslim university students in Malaysia and also examined the hypothesis that Islamic commitments to knowledge promote religious openness. Faith and Intellect Oriented Religious Reflection correlated positively and predicted openness. The Truth of Texts and Teachings factor from the Religious Schema Scales essentially assesses a form of fundamentalism and displayed direct linkages with religious openness as (...) well. Ilm factors from the Ummatic Personality Inventory correlated positively with religious openness and mediated associations of Islamic Religious Reflection with other constructs. Quest as a presumed index of religious openness proved to be incompatible with sincere Muslim commitments. These findings supplemented previous Muslim, Christian, and Hindu data in confirming the potential openness of religious traditions. (shrink)

The present study ascertained the validity and reliability of the Attitude towards Islam measure, modified from Francis's short version Scale of Attitude towards Christianity . 443 Arab Muslims from high schools and colleges in Israel with an age range of 17-38 years participated in the study. Factor analysis revealed two dimensions of the measure, labelled experiential and judgemental, in each of the samples. The findings also revealed high validity and reliability of the measure in the case of the whole scale (...) and experiential dimension, and less so in the case of the judgemental dimension.

This study is set forth to explore whether the susceptibility to persuasion—as articulated by Cialdini’s persuasion strategies—could vary with culture and acculturation. We examined individuals from the Arabic culture and their susceptibility to persuasion, according to the following strategies: reciprocity, commitment, liking, scarcity, consensus, and authority. The study involved 1,315 Arab Muslims between 18 and 60 years old. The respondents were recruited from among residents of the Arab region, immigrant Arabs in non-Arabic Muslim countries, immigrant Arabs in East Asian countries, (...) and immigrant Arabs in Western countries. Respondents completed an online Qualtrics survey. Controlling for socio-demographic variables, our results indicated that susceptibility to the strategies differed significantly among Arab Muslims in the Arab region, with reciprocity being the highest and authority the lowest prevailing strategies. The same pattern of susceptibility emerged among immigrant Arab Muslims, regardless of their host country and the acculturation mode they endorse. These findings suggest that there is a consistent persuasion susceptibility pattern in the Arabic Muslim culture that does not seem to be modified by immigration and acculturation modes. Our findings are contrasted with the scarce research on cross-cultural differences in susceptibility to Cialdini’s persuasion strategies. (shrink)

This article assesses the importance of the biblical book of Daniel in the first four Islamic centuries, focusing in particular on the legendary materials contained in Daniel 1–6. The article is divided into three sections. In the first section the treatments of Daniel 1–6 in Isrāʾīliyyāt works are examined, and it is shown that summaries of Daniel 1–6 in these works display evidence of oral transmission. Additionally, it is shown that some authors’ familiarity with Daniel legends led them to insert (...) this character into “biblical” narratives that do not otherwise relate to him. In the second section it is argued that Daniel’s exploits were so widely known that they served as a sort of yardstick for judging the relative importance of some other “heroic” figures who are described in classical Islamic sources. In the third section it is postulated that the introductory sections of Ibn Hishām’s Sīra consciously relate stories with Danielic associations in order to bring the Sīra into line with the Christian Gospels.

One of the ṣaḥābīs of Prophet Muḥammad is ʿUrwa b. Masʿūd from the Ṭāʾif tribe of Thaqīf. He belongs to the Ahlâf part of the Thaqīf tribe and he is the ruler of this part. ʿUrwa’s ancestry is known without any controversy until Kasî (Thaqīf). According to a narrative his epithet was Abū Yaʿfur and another of his epithet was Abū Masʿūd. Father of ʿUrwa an important person too. He is one of the leaders of his tribe and he commanded (...) his part (Aḥlāf) in wars of Fijār. Mother of ʿUrwa is Subay’a bt. ʿAbd Shams from Banū Umayya. In this way ʿUrwa has kinship both with Banū Umayya and Prophet Muḥammad. So ʿUrwa has a very important position because of his lineage, his mother and father. Thefore, his connections with Mecca and Quraysh strengthens his position. In our sources there is no information about his dates of birth and death. It is likely to be over middle age when he became a muslim, considering that he was the leader of his tribe and his son become a muslim after he died. There is too little information about weddings of ʿUrwa. According to narratives, he had ten wives before becoming Muslim. After becoming a Muslim Prophet Muḥammad warned from him to prefer four out of ten wives. One of his four wives is the daughter of Abū Sufyān. Howev-er, there is no information about the names of his wives. Names of his sons: ʿĀṣim, Abū Murra, Abū Mulayḥ, Dāwūd, Hammām and Hishām and names of his daughters: Umm Saʿīd (married with Ḥaẓrat ʿAlī) and Ḥalīma. We could see he served as embassy before the treaty of Hudaybiyah. His embassy duty shows us the superiority of his position. Also, this embassy duty was very effective at peace negotiations. He mentioned kinship relations which connects about Mecca. He said that it could be beneficial to talk to Prophet Muḥammad himself. The Meccans mentioned about their trust in ʿUrwa. During the time of his embassy, he expressed that both sides should be away from war. In this context, he told the Meccans: The people around Prophet Muḥammad are very loyal to him and he told to Prophet Muḥammad: People around him could disintegrate easily. This mission shows us he is intelligent, respectable and had high persuasion skills. ʿUrwa, observed loyalty of ṣaḥābīs to Prophet Muḥammad. He confessed this loyalty can not be for any ruler. This observa-tion probably affected ʿUrwa’s conversion to Islam. Because of the conquest of Meccah and the events that followed, the people of Ṭāʾif were very worried. Because of this reason people of Ṭāʾif took part in the side of Hawāzin’s and they bat-tled with Muslims. In this time they sent ʿUrwa b. Masʿūd and Ghaylān b. Salama to the city of D̲j̲aras̲h̲ of Yemen, to learn about some war machines and techniques. Therefore they did not join wars of Hunayn and Ṭāʾif. Prophet Muḥammad ended the siege of Ṭāʾif and went to Medina. Meanwhile, ʿUrwa and his friend returned from Yemen. According to narratives when the Prophet Muḥammad returned Medina or he was way in Medina ʿUrwa visited him and became Muslim. Some people tell about the date of ʿUrwa’s being Muslim at before or after Abū Bakr’s emirate of Hadj. However, when the narrations are examined, it can be said he became Muslim after four or five months from Prophet’s siege of Ṭāʾif and before three or four months from Tabūk expedition of Rabīʿ al-awwal or “Rabīʿ al-ākhir” (July or August) in the year 9/630. As for the conversion of ʿUrwa, basic sources report that “Allah, inspired Islam to the heart of ʿUrwa and he changed his situation. He went to the Messenger of Allah and he became Muslim.” They do not give a specific reason. But after this period the narratives tell the reason for ʿUrwa’s becoming a Muslim as due to an experience he had while travelling to Najrān for trade. In this travel, two mysterious young girls and the priest in Najrān said the last prophet came and ʿUrwa must be subject to him and ʿUrwa became Muslim after he returned. But this narrative is prob-lematic with regard to evidence and text. After being Muslim, ʿUrwa wanted permission from the Prophet to invite his tribe to accept Islam. The prophet did not want to accept this at first. Because the people of Ṭāʾif had an arro-gant stance against Islam, and he said that the people of Thaqīf could kill ʿUrwa. Eventually ʿUrwa went to his hometown with permission of Prophet and invited people to Islam and they did not accept this invitation and cursed ʿUrwa. The next morning ʿUrwa read adhan of fajr and people of Ṭāʾif killed him. ʿUrwa b. Masʿūd was likened to Prophet Jesus by the Prophet Muḥammad. It is generally accept-ed that ʿUrwa b. Masʿūd el-Thaqafī is “one of the biggest from two cities” expressed in sūra Zukhruf. Only two weak narrations were reported of Urwa who could live as a Muslim for a few days and was matyred by his tribe. (shrink)

Muʻtazilite thinkers put forward the first systematic ideas for the relationship of essence and attributes, one of the most fundamental and complicated issues of Islamic theology, and comprehensive explanations to the question of God’s names. Although almost all the thinkers agreed on uṣūl al-khamsa, they differed in their approach to the principle of unity (tawḥīd). ‘Abbād b. Sulaymān, who lived in the period when these approaches emerged, is a scholar who reveals his distinctive view of God’s names and attributes in (...) which heslightly differs from his contemporaries such as Abu al-Hudhayl al-‘Allāf, Mu‘ammar b. ‘Abbād al-Sulamī and Ibrāhīm b. Sayyār al-Naẓẓām from the Basran Muʻtazila, by his extreme opinions on the Muʻtazilite principle of tawḥīd. He is one of thefour principle thinkers who presented original opinions in the early Basran Muʻtazila. Also he is the only known student of Hishâm al-Fuwaṭī and constitutes the last major circle of this tradition of knowledge that ended after him. This article aims to reveal the relationship between essence and attributes, the names and attributes of God in a holistic and systematic way in the thought of ‘Abbād b. Sulaymān. Unfortunately, his works have not survived to the present day and has not received the attention he deserves. Since his views were scattered in the classic books, our study was focused primarily on these classical sources. The modern literature was not ignored, either. The relevant records, analysis and criticism were re-contextualized. According to ‘Abbād b. Sulaymān, the view that “Allah is a thing” is the same with the view that “Allah is other (ghayr)”, he draws attention to a definite distinction between Allah and human beings. In his thought about the relationship between Allah and space, he rejects the idea that God could be related to space or anything spatial in order to refrain from an anthropomorphic conception of God. In the case of visibility (ru’ya) of Allah, he radically opposes the idea of “seeing Allah with the heart,” which was adopted by the majority of the Muʻtazila. He tries to solve the issue in his own terms by avoiding the terms essence (dhāt) and nafs in the relationship between God’s essence and His attributes. He reveals a unique classification of names and thus adopts the method of analogy. He does not accept essential attributes as the majority of the Mu’tazila did. On the other hand, he tacitly accepts that Allah’s names have their own meanings in a way that they are not merely words (aqvāl). By a true comparison or perfect analogy (fī ḥaqīqati’l-qıyās), while he rejects that God is ālim, qadīr etc., he tries to ground that human beings is ālim, qadīr etc. He does not admit that God is eternally samʻi and baṣīr. Without interpreting samʻi as His knowledge or baṣīr as His power, he accepts that each name has a distinctive functionality. He rejects the assumption that God knows conditionally. Regarding the issue of whether living beings are in the knowledge of Allah before they exist, it makes a dual distinction: “a direction that can be subject to the eternal knowledge” and “the direction in which it actually came to existence”. Because of his view of non-existent and creatures, Ibn al-Rāwandī and modern resources refer the view of the eternity of objects to him. However, when the relevant records are examined, it is seen that this claim is not valid. According to ‘Abbād, Allah is capable of creating possible things that he knows, although He does not create impossible things that he knows, even though He is capable of creating them potentially (bi-al-quwwa). Allah has not created evil, neither literally nor figuratively; so much so that He created only man, not faith and unbelief. It is not possible to talk about any good that he did not create. He defends the createdness of the Qur’an (Khalq al-Qur’ān) by saying that the Qur’ān was created of accidents. About God’s names, he states that God has the names indicating His relationship to the universe. He does not accept that in eternity He is a willing agent, creator etc. However, he also does not accept the otherwise. He emphasizes that creation is reserved only for Allah. On the other hand, according to him, Allah creates without secondary causes and thus does not create things for a specific purpose. Regarding the revealed attributes (or informative attributes, khabarī), he recites these expressions only when reading of the Quran.He states that these expressions should not be used for Allah under any circumstances. He avoids naming Allah as wakīl, kafīl, laṭīf, kā’in, fard and mutakallim as he says that the name wāḥid should be used only for praising Him. (shrink)

Standard language, which follows rules of dictionary and grammar, undergoes various changes when it is the subject of literature, especially poetry. These changes, called linguistic deviation, are due to the poet’s expression of his feelings and thoughts by forcing the possibilities of language. In this direction, language deviations can be defined as the dispositions where the author goes out of the standard language, as in the examples of changes in the pronunciation (ṣavt), form (ṣarf) or spelling (kitābet) of the words, (...) the derivation of new words that are not used in the language (irticāl) and the deterioration of the syntax (naḥv). According to many literary critics such as Ibn Hishām al-Ansārī (d. 761/1360) and ʿAbd al-Qādir al-Baghdādī (d. 1093/1682), this language used by Arab poets who were not influenced by foreign languages, namely the Cāhilī, Muḥaḍram and Islāmī poets (ḳudemâ), was acceptable and it is considered as ḍarūrātuş-şiʿriyye (poetry necessities). In this context, deviations that do not comply with the standard language are tried to be explained with dialect differences, different variants of the couplet or various interpretations. However, some scholars such as Ibn Fāris (d. 395/1004) and Abū al-Ḥasan al-Jurjānī (d. 392/1001-1002) argue that these usages are laḥn (linguistic mistakes). According to these names, it is not correct to explain the poets’ use, which are contrary to the standard language rules, with excessive interpretations (takalluf). Assuming that linguistic deviations are laḥn, they cannot represent a superiority in terms of literary value, but when considered as a necessity, they represent a superiority within the framework of certain criteria. But any specific criteria have been determined before about which linguistic deviations represent the superiority. Therefore, in our study, the theories put forward about the accuracy of linguistic deviations that exceed the standard language rules will be examined and the necessary criteria for them to represent a superiority will be determined. In this direction, the difference in meaning and form that this deviation adds to the expression becomes important. If the language deviation, which is contrary to the standard sentence structure, does not comply with the language rules in any aspect and does not add any superiority to the poem in terms of meaning and form, it does not seem possible for such uses to represent a more fluent and persuasive language (al-Balāgha). However, the language deviation reveals a new meaning or form that is not found in the standard expression, and if this usage complies with the standard language rules, it represents a more eloquently language. The degree of violation of the purity and perfection of language (faṣāḥa) of a statement is related to the violation of qiyās (analogy?) and grammatical incongruity mentioned in the rhetoric books. The contravention of common language rules of these uses, which are not considered faṣīḥ, varies. As a matter of fact, some of these were seen as minor mistakes that could be ignored, while others were considered as major mistakes. For this purpose, a conceptual framework about linguistic deviations is drawn at the introduction of the article, and the literary theories on the subject are examined in the first chapter. In the second part, it is argued that linguistic deviations represent a superiority depending on certain criteria by giving examples from the poems of the period of Jāhilīyah. (shrink)

One of the important domestic developments during the Umayyad period is the rebellions carried out by members of the Ahl al-bayt. After the rebellion of Zayd b. ʿAlī in Kufa, his father, Yaḥyā was intensely prosecuted by the governor of Iraq Yūsuf b. ʿUmar, so he moved to Khurāsān, where he would feel more secure and his supporters were located. In fact, ʿAbbāsids, Kaysānī and Zayd b. ʿAlī’s supporters were active in Khurāsān. Under these circumtances, Yaḥyā left Iraq and followed (...) the road Nineveh, Madāʾin, Ray, Nīshāpūr towards the east and came to Sarakhs and resided here about six months. Here, a group from the Khārijites came and made a revolt proposal, but this proposal was rejected by those with Yahya. After this, Yaḥyā continued on his way to the east and came to Balkh and he stayed until the death of the caliph Hishām b. ʿAbd al-Malik. The general purpose of Yaḥyā’s journey from Iraq to Balkh is probably to get rid of the prosecution of Iraqi governor Yūsuf, and to establish the appropriate political atmosphere for the rebellion by contacting the Ahl al-bayt supporters in Khurāsān. The governor of Iraq Yūsuf b. ʿUmar determined the location of Yaḥyā in Balhk, and he ordered the governor of Khurāsān Naṣr b. Sayyār that he ensured Yaḥyā was imprisoned in Marw. However, as his imprisonment was reported to the caliph al-Walīd b. Yazīd, he ordered him to be released. Governor Naṣr advised Yaḥyā to go directly to the caliph and avoid situations that could cause sedition. In this case, Yaḥyā first came to Sarakhs, and then reached Nīshāpūr via Ṭūs. Meanwhile, the Khurāsān governor Naṣr wrote a letter to the governors on the route and ordered them to follow the movements of Yaḥyā and to not allow him to stay in the cities for a long time. Yaḥyā did not advance further west from the city of Bayhaq because he was afraid he might be killed by the Iraqi governor. Therefore, he returned from Bayhaq and came to Nīshāpūr. Here, they confiscated the mounts of a caravan they encountered on the way along with seventy other people, but they also paid their fees. Due to this incident, the governor of Nīshāpūr sent soldiers to Yaḥyā and his entourage, but in the clash that broke out, the supporters of Yaḥyā were successful against the soldiers, who were more than them. Yaḥyā and his followers continued their movements towards Balkh in the east after that. Even though the sources do not fully state the reason for Yaḥyā 's movement to Balkh, the geographical distance and the possible Shīʿī potential in the region may have guided him. However, this time Yaḥyā aimed to reach Balkh via Herat and Jūzjān by traveling in the southeast direction, not via Marw. Upon the news that Yaḥyā reached Jūzjān, the governor Naṣr sent an army of eight thousand men on him. Yaḥyā had to fight against the Umayyad army with his small number of supporters, consisting of seventy or one hundred and twenty people. As a result, he and his supporters were killed. Yaḥyā's head was cut off from his body and sent to the caliph, and his body was hung over the entrance gate of the city of Jūzjān. There are some reasons why the revolt of Yaḥyā failed. First of all, Yaḥyā did not prepare a road map to follow in advance for the rebellion movement, and he could not communicate with a large mass of people and did not set his goal. Secondly, Yaḥyā did not have enough support to resist the Umayyad armies in the rebellion. As a result, we can conclude that Yaḥyā was hidden during the three-year period he spent in Khurāsān because he was under prosecution and therefore could not operate openly. In addition, he could not get enough support from the Shīʿī communities in the region. Although Yaḥyā's rebellion was unsuccessful, it had some effects on the peoples of the region in the following process. Especially the murder of Yaḥyā in Khurāsān helped to create a suitable ground for the ʿAbbāsid revolution. In addition, it ensured that all Shīʿī groups were gathered under the invitation of the ʿAbbāsid "Āl-i Muḥammad”. (shrink)

Khalīfa b. Khayyāt(d. 240/854-855) was an historian- muḥaddith in the ʿAbbāsid’s period. There are references in sources to his competence in history and lineage rather than Ḥadīth. Two works of him have survived. The first one is al-Ṭabaḳāt which is about study of men and the second one is al-Taʾrīkhwhich chronologically narratesthe events in the history of Islam until 232 AH. The latter is the most significant work to be applied for the historiography of ibnKhayyāt. In this article, Khalīfa b. (...) Khayyāt’s methodology in historiography is examined. In this study, the early period of Islamic histography is handled and the subject is discussed comparatively. The main characteristics of his historiography are his adoption of a chronological style that facilitates the follow-up of the book, his knowledge for the lineage of those who died in wars and the details about the wars. Also, among the charactersitics are his application of isnād to his history book as a muḥaddith, his knowledge for the previous resources via his teachers who belong to the schools of al-Madīna and ʿIrāḳ and when required, his usage of ayah, ḥadīth and poems. These issues are dealed in the artcile with examples. Besides, a study in the West about Khalīfa b. Khayyātasserts that he was a follower of Umayyad dynasty and so this affected his historiography. In this article, this assertion is tackled by analyzing the whole book and it concludes that it is not valid because of some narrations against this assertion.SummaryKhalīfa b. Khayyāt (d. 240 / 854-55), who grew up in Basra, one of the most important centers of scholarship of the time and the meeting point of scholars, and he continued his scholarly works in this city. Since his grandfather and father are engaged in the field of Ḥadīth, Khalīfa b. Khayyāt started his scholarly adventure at an early age and he took his first education in the field of Ḥadīth.Scholars, in the early periods, continued their studies in the fields of sciences related to each other. Khalīfa b. Khayyāt’s studies are also in this kind. Although there are references in sources to his accumulation of Ḥadīth, Khalīfa b. Khayyāt ’s main area of ​​expertise is history and nasab/genealogy. The fact that his works and references to him in later sources are largely related to historical events, knowledge of the nasab/genealogy, and wafayāt (death dates of Ḥadīth scholars and narrators) reveals his considerable knowledge on these issues. Khalīfa b. Khayyāt lived in the period of ʿAbbāsid caliphs al-Maʾmūn (813-833) and al-Muʿtaṣim (833-842). This period is important because of the fact that the al-Mihna incident took place and the pressure on the Ḥadīth scholars increased. Although Khalīfa b. Khayyāt is not one of the direct opponents of Muʿtazila, his participation in a debate against them provides clues about the place where he stands. The scholarly atmosphere of Basra, enabled Khalīfa b. Khayyāt to benefit from a wide range of teacher-student network. In addition to his professors from whom he benefitted in the field of Ḥadīth, he had the opportunity to obtain the knowledge and understanding of the history of that time through his teachers who are important historians of the period in his field. Two works related to Khalīfa b. Khayyāt whose reliability is confirmed by djarh wa l tadil scholars reached to our time. One of the oldest Ṭabaḳāt works in the history of Islam is al-Ṭabaḳāt; the other one is the book, al-Taʾrīkh, which provides a new method for Islamic historiography.This study deals with the principles of the method of historiography, which can be put forward through Khalīfa b. Khayyāt 's al-Taʾrīkh. al-Taʾrīkhis important in terms of being the first example of chronological writing type in Islamic historiography and has not been subject to any independent study to date. There are two ongoing M.A. thesis about Khalīfa b. Khayyāt, however, no study has been identified that directly deals with its methodology of history. On the other hand, based on some riwāyats/narrations in al-Taʾrīkh, there is a work that claims that Khalīfa b. Khayyāt had sympathy towards Umayyads. The study named “Khalīfa b. Khayyāt’s History on the Umayyad Dynasty (660-750), prepared by Carl Wurtzel as his PhD. Dissertation, examined the life of Khalīfa, partly the historiography and the religious-political narrations in the work. On the case of Muʿāwiya’s (d. 60/680) request of the allegiance to Yazīd (d. 64/683), Wurtzel compared an event that took place between the envoy of Ibn al-Zubayr (d. 73/692) and Muʿāwiya with al-Balādhurī’s (d. 279/892-93) narrative and concluded that Khalīfa was an Umayyad sympathizer. However, Khalīfa b. Khayyāt’s exclusion of an event such as al-Mihna which was against the ʿAbbāsid and changed the course of history in his book, shouldn’t be considered as a symptom of sympathy; It would be more appropriate to accept it as a feature of history writing.At the top of Khalīfa b. Khayyāt's principles of historiography, adopting chronological method comes first. Accordingly, Khalīfa b. Khayyāt, gives a brief history about the siyar of the Prophet Muhammad at the introduction of the book. Then, by beginning from the first hijri year, he gives the important events, wars and deaths by the years. Sometimes, he refers to the people assigned by the caliphs of the period by referring to the Amîrs (Administrators) of the Hajj. He gives lists of those who died on both sides of the wars. The importance of mentioning the tribes of the deceased shows his competence in the knowledge of nasab. One of the highlights of his historiography is that he sometimes does not touch upon some of the events and situations that are considered to be turning points in Islamic history; and sometimes he does not go down into detail but just gives relevant narratives. For example, he doesn’t mention any narrations about the selection of the Caliph which perhaps the most fundamental point of separation between Ahl al-Sunnah and Shīʿa in the history of Islam.Although he gave detailed information about The Battle of The Camel (36/656) and Ṣiffīn cases (37/657), it is not possible to determine his views on this subject. In addition, he never mentioned the al-Mihna incident, which deeply influenced society and the scholarly environment during the ʿAbbāsid period. Isnād is also holds an important place in the methodology of history of Khalīfa who was a muḥaddith at the same time. In many of the narrations he used the words haddathanā and ahbaranā.In our study, the siyar section of al-Taʾrīkhwas examined in order to determine the sources of the Khalīfa’s historiography and has been seen that the works of Ibn Isḥāḳ (d. 151/768) and Ibn Hishām (d. 218/833) were the main sources of this chapter. Considering Khalīfa b. Khayyāt’s emphasize to isnād and his reach to Ibn Isḥāḳ 's work through the mediation of Bekr b. Suleiman, it can be said that he was dominant in historiography on the sources before him. Khalīfa b. Khayyāt rarely refers to Qur’anic verses and hadiths when describing events. He referred to the verses in only two places and hadiths in only five places. One of them, and perhaps the most remarkable one in the book is the Ḥadīth of the Prophet Muḥammad: “I am the guardian of whom; ‘Alī is his guardian” This narration is used in the letter of Caliph Mahdī (d. 169/785) of the ʿAbbāsid to khārijī (outer) Abd al-Salām b. Hishām who rebelled. The study is based on the principles outlined above. At the end of the study it is also considered that Khalīfa b. Khayyāt ’s works should be the subject of graduate studies which should be prepared with deep readings. (shrink)

Professor Guillaume's translation of the Sira of Ibn Ishaq is now reissued. The translator used Ibn Hisham's abridgement and also included many additions and variants found in the writings of early authors. The book thus presents in English practically all that is known of the life of the Prophet.In the introduction, the translator discusses the character of the Sira in the light of the opinion of early Arabian scholars, noting especially the difficulties of the poetry. As the earliest monument (...) of Arabian prose literature, the Sira remains a work of the first importance. (shrink)

Although Sibawayh dealt with it in a scattered manner under different headings there have been different views on na't (adjective), which is gene-rally included in the tawabi group in Arabic syntax, and there have been debates around these views. Na't, which is categorized as a proper adjective and qualifies the meaning of man'ut (mawsuf), has different characteristics from the sentence elements that indicate the subject. Nahiv scholars have mostly divided na't into two parts: real and causal na't, and they have (...) formulated certain rules for these two parts in accordance with the structure of the Arabic language. Since na't and man'ut are accepted as nouns, the i'rab of na't is subject to men'ut. However, some examples in the Qur'an and some expressions used by the Arabs caused objections to the i'rab of na't being the same as men'ut. It is observed that these objected examples are the cases where men'ut is known and the exceptional cases of madih, zam and jarri jivar. It is also obligatory for the na't to conform to the man'ut in terms of ma'rifiyyah, nekiriyyah, custom and gender. While Sibawayh (d. 180/796) considered it qabh (ugly) for non-propositional words to be na't, scholars such as Ibn Hisham (d. 218/833), Ibn al-Ḥajib (d. 646/1249), and Abd ar-Rahman Jami (d. 898/1492) accepted that na't could be either propositional or non-propositional and cited many examples of na't in the case of non-propositional words. Scholars such as Ibn Jinni (d. 392/1002) and Ibn al-Hajib gave an explanation of the causative na't without naming it, scholars such as Ebu’l-Bekā al-Ukbari (d. 616/1219) analyzed the subject under the title of causative adjective or causative na't, and Halid b. Abdullah al-Azhari discussed it under the title of al-wasf al-majazi. The subject of our study is to examine the handling of na't, which is one of the sentence elements in the Arabic language, in the works written on the field, its parts, the dimension that affects the meaning and the controversial aspects. The aim of the research is to examine the rules that Sibawayh deals with in his al-Kitâb on na'ta and the objections of later Arab linguists to these rules, and to contribute to the field by revealing different views on the subject.
