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. 

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.
