God created a man from dust and breathed life into him. Then he created a woman from man’s rib. This was the foundation of humanity. All humans ever since are children of Adam and Eve, as God says to readers of Quran ‘ Ya Bani Adam’ ;O children of Adam(Q 7:27). The story of Adam and Eve is narrated in both Bible and Quran. The two narratives that are believed to be revealed with time difference of 571 years are strikingly similar except in a few respects. Biblical narrative is more elaborative on early descendants of Adam and Eve. Quran focuses more on the reason why God created man and the beginning of Satan’s role in the man’s life. But the underlying objective of the narratives is similar, that the man and woman were lured by an enemy to eat from a tree forbidden by God. The subject of this account in Bible is a serpent, one of the wild animals God had created for man; and Iblis in Quran. Iblis is one of Jinn , another creation of God created from fire. The differences in details of the account leave some bewilderment in mind of the reader. One is forced to think that naturally this difference should not have been there if the books are from same source. Is some text changed or missed? Historical incidents suggest yes. There have been several versions of Bible in history. But historians agree that Quran was transferred down the believers very carefully and systematically. There must have been a reason why God chose to narrate the account again in his last book. Hence taking into account several significant differences in the subject of first sin of the man, one must admit that although the two narratives are from same source, the latter (Quranic) version has come with some crucial corrections to the details in the former (Biblical) narrative that had not remained in original form with passage of time. The first most striking evidence confirming the singularity of the source is similarity in details of creation Adam and Eve. Both texts are similar when they speak of creation of Adam and Eve. God created Adam from dust and breathed life into him (Genesis 2:6). Then the creation of Eve is also depicted similarly, that how God took her out of the man’s rib (Genesis 2:22). Also that God blessed them and let them live in Eden, where they could eat and drink whatever they wanted except fruit from one tree (Genesis2:7). This is also present in both texts that God created animals and plants for the use of man. In animals God made helper suitable for him (Genesis 2:18). Quran says that among animals there are some for burden and some for food (Q 6:142). So both texts are similar in revealing that the creatures on earth are for use of man. First contradiction arises here. If serpent is believed to be one of the beasts, how could that be a helper since it lured man to disobey God and God cursed it to creep on ground forever? Whether it was not serpent or a figure symbolized as a serpent. But what reason and what motive it had behind deceiving man. Biblical narrative is silent to this answer but Quran answers this very well. In fact Quranic depiction begins with the incident when Iblis refused to prostrate before man when God ordered all angles to do so. He said that he was made of fire and man from dust, so he was superior to man (Q 7:11-12). He vowed
