Zihnî temsillerin onto-epistemolojik statüsü İbn Sînâ sonrası felsefenin en tartışmalı problemleri arasında görülebilir. Problemin kökenleri bir yandan İbn Sînâ’nın farklı varlık düzlemleri arasında yüklemsel birlik elde etme teşebbüsünde, diğer yandan Fahreddin er-Râzî’nin zihnî varlık ve zihnî misallerin tümelliği eleştirisinde bulunur. Fahreddin er-Râzî’nin eleştirileri İbn Sînâ’nın önde gelen takipçilerini, İbn Sînâ’nın mahiyetlerin farklı varlık seviyelerinde korunumu ilkesini ve onun bilgiyi doğanın gayrimaddi temsili olarak tanımlamasını yeniden düşünmeye sevk etmiştir. Fahreddin er-Râzî’nin eleştirilerine karşı Nasîrüddin et-Tûsî mahiyetlerin ontolojik kapsamını daraltmış ve tümel yüklemlemeyi (...) yeniden tanımlamıştır. Kutbüddin er-Râzî’nin tartışmaya dâhil olması daraltma çabalarını daha ileri bir seviyeye taşımıştır. Tûsî’nin mahiyetlere sadece epistemolojik bir rol vererek onların ontolojik kapsamında yaptığı daraltmaya ilaveten Kutbüddin er- Râzî mahiyetlerin epistemolojik kapsamında da daraltmaya gitmiş ve İbn Sînâ’nın aklî suretlerini, hiçbir şekilde tümel olması mümkün olmayan, tikel bir zihindeki tikel suretler olarak değerlendirmiştir. Ayrıca Tûsî’yle birlikte, kendinde mahiyetlerin hariçteki fertler arasında müşterek varlığını reddeden Kutbüddin er-Râzî, bu iki adımdan yola çıkarak mutabakat ve tümellik tasavvurlarını yeniden tanımlamış, İbn Sînâ’nın hilomorfik cevher teorisi için mereolojik olmayan bir yorum geliştirmiştir. Bu makale İbn Sînâcı felsefede on üçüncü yüzyıldan itibaren ortaya çıkan bu adımları, İbn Sînâ’ya özgü gerçekçiliğin dönüşümü olarak okumakta ve bu dönüşüme giderek artan zihinselci bir eğilimin eşlik ettiğini öne sürmektedir.

Background The COVID-19 pandemic has placed an unprecedented burden on nurses who have been at the forefront of patient care. The continuous exposure to suffering, death, and overwhelming demands has the potential to lead to compassion fatigue, a state of emotional, physical, and cognitive exhaustion. Research aim The study aimed to explore and understand the phenomenon of compassion fatigue in nurses as the effect of the COVID-19 pandemic. Research design A constructivist grounded theory design was used. Participants and research context (...) The research data were collected from 20 nurses who had been employed in pandemic clinics in Turkey for a minimum of 6 months. Data were collected using a two-step approach: purposeful sample selection followed by theoretical sample selection. Individual interviews were conducted via an online platform with participants who consented to participate in the study from January 16th to April 28th, 2022. The collected data underwent initial, focused, and theoretical coding for analysis. The research findings were reported following the Consolidated Criteria for Reporting Qualitative Research guidelines. Ethical considerations Ethical approval for the study was received from Non-Interventional Clinical Research Ethics Committee. The study was conducted following the Declaration of Helsinki. Findings The study identified a core category, namely the desire to provide the best care, which was accompanied by five main categories: causes, symptoms, consequences, coping methods, and the benefits of coping methods. Conclusion During the pandemic process, nurses have experienced compassion fatigue due to various factors and have seen its symptoms. Nurses have developed various coping mechanisms individually. However, they have not indicated any institutional-level support. It has become necessary to plan nurse-centered comprehensive interventions that will reduce compassion fatigue. (shrink)

Muslims accept the existence of prophets and the occurrence of miracles as a basis of faith. The issue whether miracles will emerge from the righteous or saints is debatable. All Islamic scholars have accepted the existence of spiritual miracles, such as the grace of Allah to his saintly servants in the form of glad tidings, peace of heart and perseverance in faith. However, the existence of sensible (ḥissī) miracles or extraordinary situations that a person would never be able to do (...) under normal circumstances such as resurrecting the dead, changing the nature of objects, talking with inanimate beings and animals, knowing the events of the unseen, reaching long distances in a short time, walking on water or in the air, etc. has been the subject of serious debate. Most notably Mutazilites as well as some Sunni scholars also rejected saintly miracles and they argued that such events could only occur for prophets -with Allah’s permission and creation- and that they were called miracles. They are also concerned that if the extraordinary acts of saints are accepted, the institution of prophecy and therefore the proof of the miracle may be harmed. One of those who accepted this view is the famous Ẓāhirī scholar Ibn Ḥazm (d. 456/1064), who grew up in Andalusia. He claimed that marvelous events would occur only on the hands of the prophets, and he argued that it cannot be possible for a rightful person, saints or wizard to do extraordinary acts. However, he considered the marvelous events attributed to some people -who were not known to be prophets in the Qur’an and hadiths- as the miracles of the prophet who lived in the period in question. Ibn Ḥazm, who accepted that extraordinary events occurred from some of the ṣaḥāba (Prophet’s companions) during the Prophet’s lifetime, claimed that it ended with the death of the Prophet. According to him, those who claim that such events took place after the Prophet Muhammad, are liars, dishonest and deceitful people. In this article, the nature and limits of miracles according to Ibn Ḥazm are discussed, and the role he assigned to miracles despite being a scholar of the ahl al-ḥadīth is evaluated. (shrink)

The Successive Addition Argument (SAA) is one of the key arguments espoused by William Lane Craig for the thesis that the universe began to exist. Recently, Malpass, Mind, 131(523), 786–804 (2021) has developed a challenge to the SAA by way of constructing a counterexample that originates in the work of Fred Dretske. In this paper, I show that the Malpass-Dretske counterexample is in fact no counterexample to the argument. Utilizing a distinction between properties of members and properties of collections, I (...) argue that Malpass’ counterexample has no bearing on the soundness of the SAA. I also develop a novel parity argument against Malpass’ argument that I demonstrate can only be resolved by way of the aforementioned analysis. (shrink)

Abu Muhammad Ali b. Ahmed b. Hazm al-Andalusi (d. 456/1064), the greatest exponent of the Ẓahiriyya school, was a scholar producing important works with his identity as a jurist, hadith scholar, historian, literary man, and poet. He also persistently defended the understanding of Ahl as-Sunna against the sects that emerged within Islamic thought as he defended the superiority of Islam against other religions. In his works, he covered almost every topic of the kalam science; in this context, he was especially (...) interested in topics related to the possibility of prophethood, the prophethood of Muhammad and his being the last representative of the prophethood chain. Therefore, this study, based mainly on his works such as al-Fasl, al-Usul wa'l-Furu, ad-Durr fi ma Yecibu i'tikaduhu and Ilm al-Kalam ala Mazhab Ahl al-Sunnah wa'l-Jama'a, deals with the topics of the possibility of prophecy, the prophethood of Prophet Muhammad, and the role and importance of miracles in proving it in the view of Ibn Hazm. Almost all Islamic scholars have based their systems for recognizing prophets on the evidence of miracles. According to them, a person who claims to be a prophet must bring extraordinary evidence to confirm his claim, and it is necessary for him to do so in order to make his opponents religiously responsible. For an event to be considered evidence that confirms the prophet's claim and to be called a miracle, it must have some characteristics, such as: it must be a divine act; it must appear in an extraordinary manner; it must occur together with the claim of prophecy and challenge; and it must occur immediately after the claim of the prophet. Therefore, it is believed that evidence that possesses these characteristics can prove the correctness of the claimant without needing any other evidence. The kalam scholars only call those events as miracles, which have the characteristic of challenging the dozens of evidences that prove the prophet's truthfulness. Therefore, it is without a doubt that the concept of miracle is a special concept invented by kalam scholars. When looking at Ibn Hazm’s views on the subject, which form the backbone of the study, it is necessary to state the following: Firstly, Ibn Hazm explains that prophecy is possible, that God chooses and sends messengers among the people, and that there is no difference among the prophets in terms of belief principles. Ibn Hazm emphasizes the role of miracles in identifying prophets and bases his system on this principle. However, he does not show much care in using the term "miracles" in the way that Kalam scholars accept it and does not aim to explain or list the characteristics or attributes of miracles as seen in Kalam books. He uses the term "miracles," which have been conceptualized over a long period of time, for every extraordinary event that belongs to the prophets, without considering these sensitivities. The most striking aspect of Ibn Hazm's understanding of miracles is that he does not consider the attribute of challenge, which is defined as a condition of a miracle, as necessary. He criticizes those who accept the attribute of a challenge as an essential part of miracles and argues that such an understanding would limit the miracles of the Prophet Muhammad. If the attribute of the challenge is accepted as a condition, then extraordinary events such as the blessing of food and drink, the moaning of wood in the mosque, and some animals coming and expressing their complaints would be excluded from the scope of miracles. This would mean limiting the evidence of Prophet Muhammad's prophecy. According to him, the creator of extraordinary events is God, and He creates them only to confirm His messengers. The events that occur in the hands of a person who claims to be a prophet should be considered a miracle. Therefore, he has named every event that occurred through the prophets as a miracle, regardless of its context and nature. In conclusion, according to Ibn Hazm, there are two types of events that occur in nature: Normal events and miraculous events. He refers to the latter as miracles and limits them to only occurring in the hands of prophets. He believes that events that occur in the hands of prophets, whether they possess the characteristic of tahaddî or not, should be referred to as miracles. Events that occur in the hands of people other than prophets do not possess the characteristics of miraculous events. If such events are claimed to be miraculous, the evidence of the prophets will be damaged. Therefore, Allah creates these events only for His messengers. Therefore, in the view of Ibn Hazm, concepts such as miracles of saints (karamat), magic, and divine help (maunat) do not have a counterpart. In fact, his attitude coincides with the Mu'tazilite tradition. He tries to prevent criticism that can be directed at miracles by assigning miraculous events only to prophets. (shrink)

One of William Lane Craig's key arguments for the finitude of the past is the Successive Addition Argument (SAA). Malpass (2021) has recently developed a novel challenge to the SAA, utilising a thought experiment from the work of Fred Dretske, which is meant to show that it is possible to count to infinity, to argue that there is a counterexample to the SAA's second premise. In this paper, I contend that the Malpass‐Dretske counterexample should not worry advocates of the SAA. (...) First, I argue that one objection Malpass considers—the Potential Infinite Objection—reveals an interesting fact: the SAA's second premise is unnecessarily strong and can be weakened whilst still yielding the same conclusion. Second, I show how another one of the objections considered by Malpass—the Accumulation Objection—is successful, provided some clarification to the SAA's premises. The upshot of both analyses is that we generate two ‘new’ Successive Addition arguments that not only move the dialectic forward, but shed light on deeper assumptions and motivating intuitions concerning the Kalām.

In this paper an Artificial Neural Network (ANN) model, for predicting the category of a tumor was developed and tested. Taking patients’ tests, a number of information gained that influence the classification of the tumor. Such information as age, sex, histologic-type, degree-of-diffe, status of bone, bone-marrow, lung, pleura, peritoneum, liver, brain, skin, neck, supraclavicular, axillar, mediastinum, and abdominal. They were used as input variables for the ANN model. A model based on the Multilayer Perceptron Topology was established and trained using (...) data set which its title is “primary tumor” and was obtained from the University Medical Centre, Institute of Oncology, Ljubljana, Yugoslavia Test data evaluation shows that the ANN model is able to correctly predict the tumor category with 76.67 % accuracy.

Owner/client is a significant contributing party within the management of a project in construction. In addition to the payment of the bills related to the project, owner/client has duties and responsibilities such as selecting the professionals, making his requirements understood clearly by other parties, making decisions to recommendations and placing orders. Owner/client has to perform these duties and responsibilities at the right times and in correct ways to have the required quality and value for his/her investment. In performing his/her duties (...) and responsibilities owner could introduce positive and negative contributions to the value of the constructed facility. Value-based project management concerns with owner's/client's value system and helps owner/client in performing his/her duties and responsibilities for the optimum positive contributions to the value of the constructed facility in construction. This paper highlights the principles of value-based project management in construction and investigates the impact of owner contributions to the value of a constructed facility in practice. (shrink)

Technology plays a very important role in virtually all areas, and has become an inseparable part of the industry. Currently, industry and technology are at a high point of development and research, but there is an ever increasing gap between the market needs and the skills that universities deliver to students. There is an increasing need for consolidation between university curricula and the industry needs in terms of qualifications. In this paper we will present a description of the current state (...) of the labor market in the field of technology, including the needs that arise in improving the existing curricula of the Universities. We review the different technologies that can be used, in order to automatically gather information about the market needs in terms of job offers, and how they can be compared against University curricula. We will also present the latest achievements on these methods, and the suggestions that the researchers provide. (shrink)

It is a common intuition in scientific practice that positive instances confirm. This confirmation, at least based purely on syntactic considerations, is what Nelson Goodman’s ‘Grue Problem’, and more generally the ‘New Riddle’ of Induction, attempt to defeat. One treatment of the Grue Problem has been made along Bayesian lines, wherein the riddle reduces to a question of probability assignments. In this paper, I consider this so-called Bayesian Grue Problem and evaluate how one might proffer a solution to this problem (...) utilizing what I call a phenomenological approach. I argue that this approach to the problem can be successful on the Bayesian framework. (shrink)

Causal finitism, the view that the causal history of any event must be finite, has garnered much philosophical interest recently—especially because of its applicability to the Kalām cosmological argument. The most prominent argument for causal finitism is the Grim Reaper argument, which attempts to show that, if infinite causal histories are possible, then other paradoxical states of affairs must also be possible. However, this style of argument has been criticized on the grounds of (i) relying on controversial modal principles, and (...) (ii) providing a false diagnosis of the paradoxes involved. In this paper, I develop a new kind of Grim Reaper argument immune to these criticisms. I show that, by using insights from the literature on time travel, causal finitists should instead argue that infinite causal histories are problematically inexplicable, as they entail the possibility of unexplained foiling mechanisms. The fruits of this paper are that (i) a novel supporting argument for the Kalām is developed, and (ii) along the way of building this argument, it is shown that the literatures on time travel and causal finitism are deeply and intimately connected.

This paper is an evaluation and expansion of William Hasker’s transcendental argument against determinism. Hasker’s argument attempts to show that determinism is logically incompatible with rationality and justified belief. Hasker claims this argument to be conclusive given two independent qualifications: first that the argument only applies to a specific form of determinism, and second that the argument rests on a specific conception of rationality. My aim in this paper will be to modify and expand Hasker’s argument such that it (1) (...) applies to the more general deterministic thesis (as defined below), and (2), rests on a modified epistemic conception of rationally unaffirmable beliefs. I will attempt to do (2) by modeling Hasker’s argument after one of Alvin Plantinga’s epistemological arguments against naturalism, and hope to show that such an argumentative model is superior for the conclusion Hasker wishes to bring out. I will begin by explicating Hasker’s argument, and then I will move to the modification and expansion of the argument. (shrink)

Often, semantic accounts of ethical statements wherein those statements have their truth-conditions linked in some capacity to the mental state of an agent face the difficulty of explaining how it is that moral agents and communities genuinely disagree. However, there are––I shall argue––such semantic theories of ethical statements we can construct that avoid this explanatory deficit, insofar as they are both absolute and dispositional theories. In this paper, I will (i) explore and analyze one such semantic theory, Roderick Firth (1952)’s (...) ‘ideal observer theory’, and its relation to the problem of genuine moral disagreement, and (ii) argue that the theory successfully accounts for genuine moral disagreement in virtue of its being absolute and dispositional.

This study seeks to investigate the perceptions of elementary school 4th grade students related to the lesson and teachers of religious culture and moral knowledge via metaphors. In this study, the phenomenological design, one of the qualitative research designs, was used. Data was analysed through content analysis, and the study group was comprised of 234 elementary school 4th grade students. The sampling of the study was determined through criterion sampling, which is one of the purposeful samplings. The data of the (...) study were collected via a semi-structured form composed of two questions asked as “Religious culture and moral knowledge lesson is like … because …” and “Religious culture and moral knowledge teacher is like … because …”. The analysis of metaphors was conducted considering the stages including data encoding and extraction, the compilation of sample metaphor image, the development of themes/categories, the configuration of data based on codes and themes, the reliability and validity analyses of data, carrying out quantitative data entries and analyses and interpreting findings of the study. Considering the results of the study as a whole, it was determined that the metaphors developed by elementary school 4th grade students were largely positive related to the lesson and teachers of religious culture and moral knowledge. Summary: Metaphors are tools that try to clarify how people see life, the environment in which they live, phenomena, events and objects with different metaphors. Metaphor can also be described as meaning or experiencing something according to something else. It can be said that metaphors are mental images that help individuals to perceive their environment and to illuminate complex structures. Metaphors are tools that describe abstract events, facts, principles and rules using concrete expressions, examples and similes. Some of the basic functions of metaphors can be counted in the fact that a large number of data, revealing, interpreting, transferring information, discerning new knowledge and eliminating uncertainties. Metaphors have the characteristics of being simulation tools that make complex structures understandable, diversify perceptions about education, describe the roles of teachers and reveal the views of teachers and students about education.The aim of the current study is to examine the perception and reactions of 4th grade Elementary School students about the lesson and teachers of Religious Culture and Moral Knowledge through metaphors based on their experiences. The metaphors produced for the teacher and the lesson have the potential to give important ideas about the students' perceptions about educational activities. From this point of view, the aim of this study is to analyse the students’ perspectives about education and teaching practices by questioning the meaning that the students develop in their emotions and thoughts about the lesson and the teacher of Religious Culture and Moral Knowledge.There is no scientific study relating students’ perceptions of Religious Culture and Moral Knowledge lessons and teachers. This makes the current study unique. Considering that the perceptions of the students are formed especially during the elementary and secondary school periods, it can be said that the perceptions of the students about the lessons and teachers at early ages are necessary and important. It is thought that this study will contribute to the literature in terms of students' perceptions about a lesson and the teacher of the lesson by means of metaphors. It is thought that the fact that metaphors produced by the students in the scope of this research are answers to the questions of “what kind of teacher” and “what kind of lesson.”The current study used the phenomenological pattern among qualitative research designs. The study group consists of 234 elementary school 4th grade students. The study group was determined by criterion sampling method. Data was collected through a structured form consisting of two questions (“Religious culture and moral knowledge lesson is like … because …” and “Religious culture and moral knowledge teacher is like … because …”.) and the data obtained in the research was analysed by content analysis. Analysis of participants’ metaphors was done by taking into account the steps of coding and sorting the data, compiling the sample metaphor image, developing the themes/categories, arranging the data according to the codes and themes, conducting validity and reliability analysis of the data, quantitative data entry and analysis, and interpreting the findings.In the research, it was found out that the students produced 46 metaphors related to the lesson of Religious Culture and Moral Knowledge and the most frequently repeated metaphor related to the lesson was “the love of Allah” metaphor. It was determined that the metaphors produced in the category of the lesson of Religious Culture and Moral Knowledge were gathered in 6 categories and the category with the highest frequency was the category of “Peaceful lesson”. Regarding the teachers of Religious Culture and Moral Knowledge, it was found out that the participants produced 52 metaphors and the most frequently repeated metaphor related to the teacher was the metaphor of “Hoca” (teacher). The metaphors produced for the teacher of Religious Culture and Moral Knowledge were gathered in 7 categories and the category with the highest frequency in these categories was “the Peaceful Teacher” category.Metaphors produced in relation to the lesson of Religious Culture and Moral Knowledge can be considered as snapshots of the aims, content, learning-teaching processes and measurement-evaluation activities of the lesson. The metaphors produced about the lesson can determine the direction of the attention of preparers and decision makers in these subjects by pointing to the importance of the lesson, the importance that the student attach to the lesson, their emotions towards the lesson, the students' interests and expectations of the lesson. Metaphors produced by students in this study can be evaluated as answers given to the question of “what kind of lesson?” Metaphors produced about the teacher of Religious Culture and Moral Knowledge are important tools that reveal who the teachers are, where they stand, how they teach and how they are defined. The metaphors produced by the students can be considered as definitions from another point of view, which will enable the teacher to recognize himself/herself in many ways and to recognize him/herself more impartially. In this study, metaphors produced by the students can be evaluated as answers to the question “what kind of teacher?” When the results of the research are evaluated as a whole, it is seen that the 4th grade students' metaphors about the lesson and teacher of Religion Culture and Moral Knowledge are generally positive. In this context, it can be said that the students have positive perceptions and thoughts about the lesson and the teacher. The less negative metaphors and explanations show that the students also have negative feelings and thoughts about the lesson and the teacher. Considering the fact that students' positive feelings and thoughts about the lesson and the teacher have a significant effect on the success of the students, precautions should be taken to eliminate negative perceptions of the students by evaluating the negative metaphors about the lesson and the teacher of Religious Culture and Moral Knowledge in detail.

ABSTRACT An ethical analysis of Jordan's Clinical Research Law, which became effective in 2001, was performed. Accordingly, this paper discusses the major components, key strengths and weaknesses of this law. As an initial effort, the Law addresses important aspects of research ethics and, hence, should serve as an example for other Arab Countries in the Middle East. Unique aspects of the Law include the requirement that those conducting any study have insurance that can compensate for research injuries and a system (...) of fines and punishments for noncompliance with the Law. There are, however, some key items missing in the Jordanian Law. For example, the Law does not mention the requirement of a favourable assessment of risks and benefits, the fair selection of subjects, or articles regarding the protection of the rights and welfare of children and other vulnerable subjects participating in research. The paper concludes with the suggestion that new amendments should be considered for future revisions of the Clinical Research Law in Jordan. (shrink)

We examine the role of religiosity on the financing activities in both Islamic and conventional banks in Indonesian provinces by using five different measures of religiosity: number of Islamic schools, hajj application, number of Islamic seminary schools, number of Mosques, and number of certified halal products. Based on regression analysis, the results show that both Islamic and conventional banks provide more financing in religious provinces. Religiosity also helps in reducing the volume of non-performing financing. Our the results are still qualitatively (...) valid after taking into account endogeneity issue that emanates from omitted variables (i.e., unobservable beliefs, ideas, and attitudes), and possible reverse causality between religiosity and the total amount of financing at the province level.

We examined the direct and indirect (via relational social capital) relationship between ethical leadership and knowledge hiding. We also tested the moderating role of instrumental thinking in the relationship between ethical leadership and knowledge hiding and the relationship between ethical leadership and relational social capital. Data were collected from 245 employees in different firms spanning different manufacturing and service sectors. The results showed that ethical leadership was negatively related to knowledge hiding, both directly and via relational social capital. The results (...) revealed that instrumental thinking moderated the positive relationship between ethical leadership and relational social capital, such that the relationship was weak when instrumental thinking was high. The results also showed that instrumental thinking moderated both direct and indirect relationships between ethical leadership and knowledge hiding, such that the relationships were weak when instrumental thinking was high. The study carries important practical implications for managers concerned about the destructive consequences of knowledge hiding. (shrink)

The purpose of this paper is to determine whether there is a relationship between a person's degree of religiousness and corporate social responsibility orientation. A total of 411 managers and 506 students from seven universities were surveyed. The statistical analysis showed that religiousness does influence students' orientation toward the economic, ethical, and philanthropic responsibilities of business. It does not, however, have a significant impact upon the managers' attitudes. When the "low religiousness" students and managers were compared, differences were found with (...) respect to the economic, ethical, and philanthropic components of corporate social responsibility. Similar results were obtained when the "high religiousness" students and managers were compared. The implications of these findings are discussed. (shrink)

In this paper, a nonlinear dynamical system is proposed and qualitatively analyzed to study the dynamics and effects of HIV-malaria co-infection in the workplace. Basic reproduction numbers of sub-models are derived and are shown to have LAS disease-free equilibria when their respective basic reproduction numbers are less than unity. Conditions for existence of endemic equilibria of sub-models are also derived. Unlike the HIV-only model, the malaria-only model is shown to exhibit a backward bifurcation under certain conditions. Conditions for optimal control (...) of the co-infection are derived using the Pontryagin’s maximum principle. Numerical experimentation on the resulting optimality system is performed. Using the incremental cost-effectiveness ratio, it is observed that combining preventative measures for both diseases is the best strategy for optimal control of HIV-malaria co-infection at the workplace.

In Islam, there is a belief that Allah has a ‘throne’ [al-ʿArsh, the highest level of the heavens] in the sky and that Allah sent the Qurʾān directly from that throne or through an angel. According to this belief, the Qurʾān descended from the seventh level of the heavens to the first level and then completed its descent to the earth in pieces over 23 years. Accordingly, the Qurʾān descended from a certain place with determined borders, namely from the throne (...) [al-ʿArsh] of Allah. However, theological books [the literature and sources of ʿılm al-Kalām] contend that Allah is free from space and time and that a specific space cannot be attributed to Allah. The verses of the Qurʾān even suggest that Allah is not only above in the heavens but everywhere. Therefore, the main question of our article is why Allah wanted to send the Qurʾān specifically from the heavens if Allah is free from space. We show that the descent of the Qurʾān from the heavens to the earth is not realistic but is a symbolic and metaphorical narrative. (shrink)
