Hail is an atmospheric rainfall with a complex mechanism. The Greeks were among the pioneers of knowledge in ancient times and they termed “hail” as “frozen rain” (Anaximander) and “instant freezing of water and moisture” (Aristotle, n.d.). These two meanings are inconsistent with current scientific facts. The Noble Qurʼan is the most authentic text to encourage Muslim believers to think about creation and strengthen their faith in the eternal power of the Creator. For instance, the mechanism of hail falling has been expressed in the verse (Q.24:43) with specific and gradual indications. In this research, first, by library method, different explanations of this verse were obtained from valid interpretive sources and then, the scientific findings of meteorologists and climatologists on hail were extracted from reference scientific texts on atmospheric sciences. In the third stage and based on comparative method, the scientific rules were placed next to interpretations to test the novelty and degree of the allusions of this verse. We found that the stages of hail falling included:“invisible water vapor rises from the sea,” “water vapor ascends into the atmosphere,” “reaching the condensation stage,” “cloud formation,” “convergence of ascending currents,” “formation of cumulonimbus cloud,” “growth of hailstones during successive ascents and descents by adsorption and freezing of ice needles,” and finally “their fall down over ground” respectively. Meanwhile, the steps in the Noble Qurʼan are mentioned in verse (Q.24:43) in the following order:“clouds movement slowly,” “clouds convergence,” “clouds accumulation,” “the formation of mountain-like clouds,” and “hail falling from the clouds.” The results also showed that likening cumulonimbus cloud in the verse (Q.24:43) to “mountain” have four respects that were beyond the comprehension of the people at the time of the revelation of the Qurʼan. Nowadays, these features are known to stationary and satellite meteorological instruments. These four characteristics are “cloud layer temperature,” “their constituent phase,” “troughs and ridges inside the cloud” and “cloud height up to the tropopause.” Based on these four characteristics, the Noble Qurʼan considered the cloud of cumulonimbus as similar as “mountains.” Meteorologists divide any cumulonimbus cloud into three floors, including cold at the bottom, super-cold at the top and intermediate in the middle. We find these three floors in the same way in the high mountains. These floors are the current rivers (liquid phase), snow and ice reserves (solid phase) and in the middle region a combination of two liquid and solid phases, namely water and ice. Images from the cumulonimbus from above the atmosphere show dark and deep valleys and light and raised ridges. The fourth feature is to be said, none of the surface phenomena are as high as the mountains. Finally, meteorological findings show that it is the only cumulonimbus that rises from the ground to a height of 12,000 meters and more. 

.The Holy Qur'an introduces the concept of intellect as an instrument for thinking and recognizing the facts and in several verses with different expressions, insists on activating the intellect by human. in order to convey this issue precisely and deeply to the audience, The Qur'an has used many synonymous and close concept to intellect, such as tafakur (thinking), qalb (heart), lubb (heart of the matter), nuhā (understanding), ḥijr (evidence), ḥilm (reason) and fiqh (realization). The authority of the intellect in recognizing facts has been confirmed in the Qur'an and Islamic traditions. One of the most important subject matters that should be identified by the intellect is the domain of beliefs and theology, which also leads to the perception of the prophetic mission and resurrection. Another issue perceived by the intellect is the realm of recognizing moral virtues. According to several verses and traditions, human intellect can discern good and evil, regardless of religious teachings, although some Islamic sects do not believe in this. It can be said that the power of intellect in human is like an intrinsic prophet whose discernment is authoritative and in agreement with the guidance of the prophets. Thus, from the Qur'an's point of view, the realm of intellect in knowing facts is a vast scope which comprises various subjects such as theology, ontology, anthropology and ethics. 

The present semantic research has been performed in order to provide a cognitive and cultural explanation of conceptual metaphors in parts 20 to 30 of the Holy Qur’an. Extraction of ‘types of conceptual metaphors,’ determination of ‘high frequency metaphors,’ ‘source domains’ and ‘target domains’ is the process of conducting research using the conceptual metaphor theory. The variety of concepts of ‘target’ and the functional frequency of ‘source’ concepts indicate what concepts are intended in the holy Qur’an through metaphorical conceptualization. This study provides a basis for further understanding of the worldview presented in the Holy Qur’an and the possibility of determining the behavioral patterns of religion by identifying metaphors. The results of the present study represent a septenary classification of metaphors in the ‘empirical source domain,’ containing: ‘social life,’ ‘needs of the body and its activity,’ ‘image schemas (schema-based),’ ‘elements of nature,’ ‘person,’ ‘body parts,’ and ‘similarity-based metaphors (simile)’; Among which, the highest percentage of metaphorical conceptualization in the source domain is in ‘social life’ and the lowest one is in the domain of ‘person.’ Considering the fact that most of the human knowledge is about the elements and subdomains of ‘social life,’ Qur’anic sources in this domain have played the major role in abstracting the cultural and doctrinal concepts of religion and organizing Islamic religious experiences using the sources of this field and have been used as customary (conventional) and practical models. Accordingly, Qur’anic metaphors lead to the formation of cultural and cognitive patterns, and the ‘monotheistic belief system’ (Qur’anic) directs human bodily experiences in metaphorical conceptualization, and this ‘Qur’anic worldview’ can be seen as an Islamic cultural and cognitive model in the Qur’anic metaphorical schema. 

Some religious modernists believe that correct and scientific comprehension of the Qur’an is merely provided through historical and cultural study of the context of revelation time. Others, on the other hand, advocate that knowing interior and connected evidence suffices for Qur’an comprehension. Further, they say that exterior and unconnected evidence such as cultural and historical studies can have little effect on Qur’an comprehension. These various attitudes made us research them and represent a model to assess the dependency of Qur’an comprehension on cultural and historical conditions of revelation time. The present study examined works of scholars in this field such as Nasr Hamid Abu Zayd, Khorramshahi, and Tabatabaei through a descriptive and analytical method. Then, a model was recommended to evaluate the dependence of understanding of the Qur’an on the cultural and historical conditions of revelation time. The model includes four components: cause of revelation; vocabulary; subject matter; expressions which encompass twelve rules based on the features of verses in each component. Input of the model is one verse and its output is a dependent, independent, or semi-dependent mode.

Examining the orthography of the Qurʼan shows that the letter alif was omitted in some words, while it was not omitted in similar words. Scholars have offered various reasons for eliminating alif since the early centuries. Some of them regarded the way of writing the Qurʼan as sacred or proposed ideological explanations for it. However studying these justifications shows that they are not subject to scientific linguistic rules and are mostly personal opinions. Because based on the ancient manuscripts of the Qurʼan, we can find many contradictions for the proposed reasons, which shows that they are not general and true in many cases. Using the reasons presented in the books of Qurʼanic sciences and some interpretations of the Qurʼan and comparing them with the orthography in the manuscripts, this study shows that the orthography of the Qurʼan, especially in the case of writing alif, is a linguistic and scribal phenomenon subjected by some factors that developed the Arabic script in its early stages.

In this paper, we try to show, based on scientific evidence, that assigning consciousness to humans and calling the "world without humans" meaningless does not seem like a comprehensive approach. The intellectual foundation of this attitude is based on a kind of "spectral approach" in examining the phenomena of the world. To explain this attitude, we refer to evidence of scientific findings to show that our lack of understanding of the consciousness of other beings does not mean the lack of intelligence in them. We also show that many phenomena in this world are spectral. Then, based on the verses of the Qur'an and the concept of the dignity of beings from the perspective of Islamic philosophy, we conclude that other creatures also have a hierarchy of intelligence that we describe here as "the spectrum of consciousness".

The study of surahs' structure has attracted researchers' attention in recent years. One of the theories herein is the theory of Topic Sameness which acknowledges that each surah of Quran has formed on a single topic. The theory of Introduction and Explanation as one of the most important branches of Topic Sameness, proposes that the Almighty states the topic of each surah at the first section, elaborates it at different parts of the surah in the forms such as stories, signals of nature, and future predictions, and concludes from the stated contents at the final part. In this paper, we accordingly intend to study the two theories using NLP techniques for the first time. In this regard, based on the three methods of tf-idf, word2vec and roots' accompaniment in verses, the similarity of Quranic roots is computed. Then, the amount of similarity of the concepts within surahs to each other is calculated and compared with the random mode. The results show that the studied surahs hold the inner coherence between the concepts so that they have been formed on a single topic or a few topics related to each other. In addition, the study on the similarity between the first and the body sections of each surah shows that the structure of Introduction and Explanation seems to be true for many surahs by the designed methodology. At the end, by comparing the similarity of surahs to each other versus their order distance in Quran and their revelation time distance, we realized that the whole Quran is also relatively organized in terms of surah' ordering.
