Falling down in the Quran is one of the serious issues, and even though it is in other divine religions, but each of them has interpretations on it that are worthy of reflection. What is dominant in all religions, including Islamic interpretations, is that this decline is a form of degradation and humiliation of man, and this was due to a wrong action that Adam did and was influenced by Satan and disobeyed, or in a milder term, it was desertion of the first. He did it and if he didn't do that, maybe the fate of man would have been different or he would have stayed forever in heaven. It seeks to answer the question, what is the opinion of Mulla Sadra and Allameh Tabatabai about descent in the Qur'an? The principles of descent are stated in several verses of the Holy Quran, and the expulsion of Adam from heaven and his settlement on earth are interpreted as descent. Also, among the commentators, the issue of declining status has been raised, and among the philosophers, each of them has expressed ideas and possibilities in this field. The findings of the research indicate that Mulla Sadra considers Adam's sin to be the fourth position of the arc of human descent before the beginning of life on earth. In his opinion, Adam's disobedience was not an external event and the Qur'an's statement regarding the nature of man is one of the characteristics of human nature It is noted. However, several verses of the Qur'an, referring to Adam and Eve being deceived by Satan and revealing their private parts after disobedience, have called this interpretation into question and have explicitly mentioned this as an external event, to the point where they say that these two tried to Let the heavenly trees cover their ugliness. The importance of this issue is because so far no one has criticized Mulla Sadra's interpretation of Adam's paradise and his disobedience from the perspective of religion. Allameh Tabatabai interprets the flow of descent as an anthropological structure. They believe that these few verses about the creation of Adam in Surah Baqarah, Araaf and Taha have an anthropological structure. He believes that the extract of what is seen in all the holy books is contained in these verses.
