Al-Ghazali (1058-1111) was concerned that early Islamic philosophers were leaning too heavily and uncritically on Aristotelian and Neoplatonic ideas in developing their models of God and His relation to the world. He argued that their views were not only irreligious, but philosophically problematic, and he defended an alternative view aimed at staying closer to the Qur’an and the beliefs of the ordinary Muslim. Ibn Rushd (1126-1198) responded to al-Ghazali’s critique and developed a sophisticated Aristotelian view. The present chapter explores their (...) views in light of a problem facing any philosophical model of God in Islam or classical theism more generally, the problem of conceiving of God’s nature and relation to the world in a way that places an appropriate distance between God and humans. On the one hand, we want a notion of God that is not overly anthropomorphic, or that does not make him to be too much like us. On the other hand, we want to be able to say something positive and substantive about God. And we want to do this while preserving the harmony of reason and revelation, of philosophy and religion, as much as possible. (shrink)

Although there are fundamental differences between Ahl al-Sunnah and Shī‘a on the issue of Mahdī, one of the controversial issues among Islamic sects, Shī‘a has attached much greater importance to the issue. In this study, after the information about Mahdiship in the primary sources of Islam is conveyed, the opinions of the Ahl al-Sunnah and Shī‘a will be given and an evaluation will be made about the evidence and opinions put forward by the two sects. The Shiites, who formed the (...) principles of belief based on the theory of imamate, explained the issue of Mahdism in the axis of imamate and gave it a religious dimension, but the Shi‘ī sects disagreed on the subject of Mahdī. Shi‘ī sources tried to show that the claim of Mahdiship is an important issue, which has preoccupied Muslims, by dating the claim of Mahdiship back to Ali ibn Abi Talib's son, Muhammad ibn Hanafiyah. In a very early period, it was claimed that Muhammad ibn Hanafiyya did not die but was still living on a mountain called Razva in Madinah, and he was the anticipated (muntaẓar) Mahdī. Most of the Zaydiyya did not consider the issue of Mahdiship an important fundamental basis of belief. Ismailiyya maintain that Muhammad ibn Ismail did not die and will come and amend the world one day. Imāmiyya believe that Hasan, whom they accept as the last imam, will reappear as the Mahdī in the latest days of the world, and in line with this belief, they have made great efforts to find proof from the Qur’ānic verses and hadiths and interpreted them. In this way, they attached more importance to the understanding of Mahdiship on the axis of imamate than the other Shi‘ī sects. According to Imāmiyya, since the world cannot be left without a prophet, an open, or a secret imam, Muhammad b. Hasan will remain hidden as long as he wants and appear as the Mahdī near the Doomsday. Based on the clear statement of the Messenger of Allah (pbuh) that twelve caliphs would come after him, the Imāmiyya restricted the number of Imams from Ahl al-Bayt to twelve and claimed that the twelfth imam would come again as Mahdī. Although the Imāmiyya believe that the Mahdī will be from the Ahl al-Bayt, just like the other imams, they have not been able to provide valid evidence for the belief that the twelfth imam will be hidden and appear near Judgment Day. Although Imāmiya tried/have been trying to prove that it is possible for a person to live for centuries (more than a thousand years), which is called al-Ghaybat al-Kubrā by Imamiyya, it cannot be said that they have succeeded in doing so.

The main evidence used in a matter of proving prophethood in Kalām is miracles. For this reason, other extraordinary situations that miraculously occur have always been on the agenda of theologians. Of these the most similar to miracle is karāma events that occur extraordinary in the hands of Walī. Karāma has been discussed on certain theoretical grounds in kalām books during the beginning period of Sunnī kalām. As in other theological debates, the leading adversaries of Sunnī theologians in the issue (...) of karāma were Muʿtazilite theologians. This study discusses approaches towards karāma in early period of Sunnī kalām. Accordingly, the scholars who determined the basic approaches of Ashʿariyya and Māturīdiyya kalām schools are included in the study. İmām al-Ashʿarī, Ibn Fūrak, al-Bāqillānī, ʿAbd al-Qāhir al-Baghdādī, Abu’l-Maʿālī İmām al-ḥaramayn al-Juwaynī, Abū ʿAbdallāh al-Ḥalīmī and Abū Isḥāq al-Isfarāyīnī from Ashʿarī school; Abū Manṣūr al-Māturīdī, Ḥakīm as-Samarqandī, Abū al-Yusr al-Bazdawī and Abū al-Muīn an-Nasafī from Māturīdiyya school, in this context, are included in the study. Besides, some authors from fields other than kalām are included in the scope of the study in order to determine the first use of the concept of karāma and different approaches are discussed. In the study, after the views of the theologians on the subject are presented descriptively, these views are critically assessed. (shrink)

This study seeks to investigate the treatise of Abū al-Hasan b. Abd al-Rahman b. Muhammad al-Khatīb al-Shirbīnī al- Shāfiʻī (d. after 1028/1619) entitled Fatḥ al-Raḥīm al-Raḥmān fī tafsīr Āyat "inna Allāha yaʼmuru bi al-ʻadl wa al-iḥsān" based on the manuscript of the author. Shedding light on the translation of this unknown scholar, as it is evident from the title of the treatise that it contains the interpretation of this verse, which is well known among scholars and commentators as the (...) most comprehensive verse in the Qur’ān. In this tafsīr, Shirbīnī used many exegetical methods such as exegesis of the Qur'ān with the Qur'ān, exegesis of the Qur'ān with the Sunnah, exegesis of the Qur'ān with the sayings of the Companions, and al-tafsīr bi-al-raʼy, as well as tafsīr approaches such as linguistic tafsīr, the science of munāsabāt, and causality of nuzūl to analyze the meanings of the verse in depth. Another feature that increases the importance of this treatise is that al-Shirbīnī refers to the primary source tafsīr books together with their glosses, sometimes quoting from the commentators verbatim, and sometimes making meaning-based quotations from them, which is the most obvious indication of his exegetical ability and scholarly competence. In this work, he adopted a syncretic approach while emphasizing the meanings of the verse and followed an analytical-critical method while examining the subject. For this reason, he analyzed all the words in the verse one by one, dwelt on the meanings and interpretation of the words, and criticized their views after including the views of the commentators. Therefore, he applied the analytical exegesis method very successfully in this work. Accordingly, he analyzed the narrations related to tafsīr and mentioned the Companions' names during the narration. In particular, he analyzed the narrations from Ibn 'Abbas (d. 68/687-88) about the words al-ʻAdl and al-iḥsān, and stated that there was a dispute between the narrations about the phrase al-iḥsān. He took a scientific stance on the derivation of the word "Allah,” debated between those who accepted it and those who rejected it. He stated that the derivation of the word was not satisfactory and reliable. In the tafsīr of the words al-ʻAdl and al-iḥsān, he discussed the isnāds in Muqātil b. Sulayman’s (d.150/767) tafsīr emphasizing that he received the tafsīr of al-ʻAdl from Ibn 'Abbas and the tafsīr of al-iḥsān from 'Ali b. Abī Tālib. This approach is an important example for the isnād analyses of Muqātil b. Sulayman who was criticized for neglecting isnād chains in his tafsīr. He also criticized al-Baydāwī for being influenced by some of Zamakhsharī's sectarian and theological views. He classified the issue of kinship according to usūl, furū', and hawāshī, expanded the meaning of the verse, and insisted that the message of this verse encompasses all relatives, regardless of the degree of kinship. He was influenced by Latāʾif al-Ishārāt, al-Kashshāf, Mafātīhu al-ghayb, al-Baydawī, Hāshiya al-Jurjānī ala al-Kashshāf, and his grandfather al-Khatīb al-Shirbīnī’s (d.977/1570) al-Sirāj al-munīr.

It is well-known that Ibn al-Salāh al-Shahrazūrī (d. 643/1245) has an important place in the field of hadith methodology. In this context, it is possible to see Ibn-al Salah’s influence in a large proportion of the hadith terminology. The fact that the term ḥasan was not substantially included in the hadith method studies before Ibn-al Salah and that this concept became widely known in the field after him led to study the contributions of al Salah on the subject of ḥasan (...) hadith and in this regard, his effect on the term ḥasan. As result it was found that authorities such as Shāfiʿī (d. 204/820), ʿAlī b. al-Madīnī (d. 234/848-49), Ahmad b. Hanbal (d. 241/855) used the concept of ḥasan in various meanings before al-Tirmidhī (d. 279/892) who, according to general acceptance, made the term ḥasan famous for its terminological use. However, it is possible to say that ʿAlī b. al-Madīnī was the first to use the terminological meaning of the concept ḥasan. Actually, the fact that Shafii’ used the term ḥasan isnād for an authentic hadith that al-Bukhārī (d. 256/870) and Muslim b. Ḥajjāj (d. 261/875) would later unanimously narrate, and Ahmad b. Hanbal used ḥasan as gharib, is evidence for the unsystematic use of the term in the early periods. Even though, thanks to al-Tirmidhī, an important place was opened for the concept in riwāya literature, there was no serious mention of the term in later hadith methodology. Therefore, it has been seen that hadith scholars considered the term ḥasan within the scope of ṣaḥīḥ or ḍaʻīf hadith, since they accepted the term as an intermediate concept, and for this reason they did not include the term ḥasan among the subjects of hadith methodology until Ibn al-Salāh. An examination of the argument, that one can act upon a ḍaʻīf hadith, would show that ḥasan hadith might have been interpreted within the scope of ḍaʻīf hadith. On the other hand, the fact that some scholars such as Mughulṭāy b. Qilīj (d. 762/1361) state that a hadith would be called ṣaḥīḥ if it is maqbūl with any presumption, and that there is no point in calling such a hadith ḥasan shows that the ḥasan hadith is considered within the scope of ṣaḥīḥ hadith. The fact that hadith methodology scholars did not mention ḥasan hadith before Ibn al-Salāh stems from the ambiguity of the subject. Contrary to his predecessors, Ibn al-Salāh tried to save the term ḥasan from its ambiguity by combining the different specifications put forward by al-Tirmidhī, al-Khaṭṭābī (d. 388/998), and Ibn al-Jawzī (d. 597/1201). The specifications and interpretations of the term presented by Ibn al-Salāh via his meticulous efforts, have also been adopted by his successors. The term ḥasan hadith has gained an important place in the literature of hadith methodology thanks to the views and definitions built on the descriptions and interpretations of Ibn al-Salāh. In this context, while there are those who agree with Ibn al-Salāh’s descriptions and evaluations of the term, there are also those who criticize his remarks on the subject. However, it has been seen that those who criticize Ibn al-Salāh, along with those who follow him, criticized him by following the path drawn by Ibn al-Salāh. Based on this and similar situations, it was concluded that not only the descriptions and comments that Ibn al-Salāh made, but also his style and methods of handling the subject gave direction to the studies on hadith methodology. In addition, it has been observed that the most compact description of the term ḥasan is put forward by Ibn Hajar and today’s studies are predicated on his description. Within this framework, after emphasizing that there are four degrees of maqbūl hadiths, Ibn Hajar defined the two fields, which were covered by two different descriptions of Ibn al-Salāh, as ḥasan li-zatih and lighairih by Ibn al-Ḥajar. (d. 852/1449) By doing so Ibn al-Ḥajar gave the final shape to the ḥasan hadith terms. He also captured the fundamental point where ḥasan hadith differs from the ṣaḥīḥ hadith because the basic point in question, which was not directly stated before, is a slight flaw in the narrator’s grip. At the end of the study, it was concluded that -as al-Dhahabi (d. 748/1348) also stated- it does not seem possible to determine a comprehensive rule that gathers ḥasan hadiths under a single description. Considering the historical context of the term ḥasan, it has been observed that the most effective description of the ḥasan hadith are the terms ḥasan li-zatih and ḥasan lighairih, which were put forward by Ibn Hajar by transforming the dual division mentioned by Ibn al-Salāh into a more understandable form.

It was widely believed among post-classical thinkers that the classical Mutakallimūn held that the cause of dependence of an effect on a cause was its origination, or a combination of origination and contingency, or its contingency on condition of its origination. Some post-classical thinkers, led by al-Sayyid al-Sharif al-Jurjānī, went further by interpreting Abu’l-Hasan al-Ashʿarī’s denial of the persistence of accidents was a consequence of his view that origination was the cause of dependence. This is because the origination view (...) entailed that the world was no longer in need of the Creator after its origination, and thus, him and his followers sought to deflect this consequence by holding that accidents do not persist, and since the persistence of substances was dependent on those accidents, and accidents do not persist more than one moment, those substances remained in need of the Creator for those accidents after their origination. This article seeks to investigate this analysis of the Shaykh al-Ashʿarī’s view, alongside the leading scholars of his school. After examining the original sources of classical Ashʿarī thinkers, along with the Baṣran Mu’tazila, and the texts of Ibn Sina, it becomes clear that the Ashꜥarīs did not hold that accidents did not persist in order to deflect that purported consequence. Indeed, it becomes clear that they did not hold that origination was the cause of dependence, but rather, that it was contingency. As for the Mu’tazila, they are explicit that the cause of dependence is origination, and that is based on their view on the reality of the nonexistent. Since essences are real in their state of nonexistence, they are not in need of a cause; and everything that obtains for those essences after they come into exist are entailments of that essence; thus, they only stand in need of a cause in their origination, that is, going from nonexistence into existence. Indeed, they are also explicit that effects do not need the Creator after their origination, and they clarified this through a comparison with a builder and a building. Indeed, the classical Ashꜥarīs criticized them for this, just as Ibn Sina did in the Ishārāt wa’l-tanbīhāt, al-Najāt, and al-Shifā. Thus, those post-classical scholars generalized the statement that origination is the cause of dependence to all classical mutakallimūn, and then they interpreted Ashʿarī’s motivation behind the denial of the persistence of accidents in accordance with that. The truth, however, is that his view on accidents is based on contingency, and that is because a substance is possible of persistence and possible of non-persistence, and therefore, it stands in need of cause to determine its state in the subsequent moment. That determination must entail something additional to the substance itself, otherwise, the effect is redundant. That additional property must be an accident, and since it is impossible for an accident to subsist in an accident, it is not possible for an accident to persist, because it is not receptive to the property which entails persistence; meanwhile, it is possible for substances, because they can sustain accidents.

Construction cost estimation is one of the essential processes in construction management. Project cost is a complex engineering problem due to various factors affecting the construction industry. Accurate cost estimation is important in construction management and significantly impacts project performance. Artificial intelligence models have been effectively implemented in construction management studies in recent years owing to their capability to deal with complex problems. In this research, extreme gradient boosting is developed as an advanced input selector algorithm and coupled with three (...) AI models, including random forest, artificial neural network, and support vector machine for cost estimation. Datasets were gathered based on a survey conducted on 90 building projects in Iraq. Statistical indicators and graphical methods were used to evaluate the developed models. Several input predictors were used, and XGBoost highlighted inflation as the most crucial parameter. The results indicated that the best prediction was attained by XGBoost-RF using six input parameters, with r-squared and the mean absolute percentage error equal to 0.87 and 0.25, respectively. The comparison results revealed that all AI models showed good prediction performance when applied to datasets affected by more than two parameters. The outcomes of this research revealed an optimistic strategy that can help decision makers select the influencing parameters in the early phases of project management. Also, developing a prediction model with high precision results can assist the project’s estimators in decreasing the errors in the cost estimation process. (shrink)

Composed by Najm al-Din al-Katibi, a scholar of the Shafi'i school of law, al-Risalah al-Shamsiyyah is the most widely read introduction to logic in the Arabic-speaking world. It has probably enjoyed a longer shelf-life than any other logic textbook ever written, having been in use by madrasa students from the early fourteenth century up until the present day. Building on (...) the theories of Avicenna, al-Razi, and other pioneers of logic, al-Katibi discusses the many pitfalls of building arguments and setting out unambiguous claims in natural language. The enduring nature of the text is a testament to al-Katibi and his impact on concepts of formal discourse and argument. (shrink)

Logic was revered in the thirteenth century, perhaps more highly than it has been revered before or since. In the Muslim East, logic was an integral part of the syllabus of schools and found to be especially helpful for legal studies. It was at this time that The Canons of Logic was composed by Najm al-Din al-Katibi, a scholar of the Shafi'i school of law. The Rules of Logic is the most widely read introduction to logic in the Arabic-speaking world. (...) It has probably enjoyed a longer shelf-life than any other logic textbook ever written, having been in use by madrasa students from the early fourteenth century up until the present day. Building on the theories of Avicenna, al-Razi, and other pioneers of logic, al-Katibi discusses the many pitfalls of building arguments and setting out unambiguous claims in natural language. The enduring nature of the text is a testament to al-Katibi and his impact on concepts of formal discourse and argument. This new translation of The Canons of Logic provides new life to an influential text that has shaped the work of scholars of logic for centuries. (shrink)

The Persian philosopher Ibn Sina (d. 1037), known in Europe as Avicenna, was arguably the greatest master of Aristotelian thought in the Muslim world. The symbolical 'Poem on the Soul' (Qasidat al-nafs), which portrays all earthly human souls as in temporary exile from heaven, is traditionally attributed to Avicenna, and was received with enthusiasm by its commentators. A highly significant commentary on the Qasida was written by?Ali b. Muhammad b. al-Walid (d. 1215 CE), a major early representative of the Tayyibi (...) Ismaili tradition, which emerged and flourished in medieval Yemen. In his view, the poem encapsulated Tayyibi beliefs, whose doctrines bear striking parallels with late antique Gnosticism. Avicenna's Allegory on the Soul presents the first edition of the Arabic text of Ibn al-Walid's commentary, 'The Useful Epistle' (al-Risala al-mufida), alongside an English translation and extended introduction. It offers invaluable insight into the intricacies of Muslim thought and a deeper understanding of Avicenna's substantial intellectual legacy. (shrink)
