Adam and Eve were admitted to Paradise and there they lived the dream of all human beings. Allah permitted them to approach and enjoy everything except one tree, that might have been the Tree of Pain or the Tree of Knowledge. Allah forbade them before they were given abode in Paradise: "0 Adam! Dwell you and your wife in the Paradise and eat both of you freely with pleasure and delight of things therein as wherever you will, but come not near this tree or you both will be of the Zalimeen (wrong-doers). " Surah 2: 35
Adam and Eve understood that they were forbidden to eat the fruit of that tree. Adam was, however, a human being, and man tends to forget. His heart changes and his will weakens. Iblis summoned all the envy within him and took advantage of Adam's humanity to exploit him. He started to whisper to him day after day, coaxing him: "Shall I guide you to the Tree of Immortality and the Eternal Kingdom?" And he said to them: "Your Lord did not forbid you this tree save you should become angels or become of the immortals." And he (Satan) swore by Allah to them both (saying): "Verily, I am one of the sincere well-wishers for you both." Surah 7: 20-21
Adam asked himself: "What will happen if I eat from this tree? It might truly be the Tree of Immortality." His dream was to live forever in the pure innocence of Paradise.
Years went by, and Adam and Eve were preoccupied with thoughts of that tree. Then, one day, they decided to eat of its fruit. They forgot that Allah had warned them not to approach it and that Iblis was their sworn enemy. Adam stretched out his hand, picked one of the fruits, and offered it to Eve. They both ate of the forbidden tree.
Allah Almighty told us: "So he Satan misled them with deception. "2 Surah 7: 22 Allah also said: Thus did Adam disobey his Lord, so he went astray. Surah 20: 121
According to the Old Testament, Eve was tempted by the serpent to eat of the forbidden tree. She ate because of the words of the serpent and fed Adam some of it. At that moment, their eyes were opened to the fact that they were naked, and they took the leaves of the fig tree to cover themselves. Wahb Ibn Munabah said that their clothing (before their sin) was made of light on the private parts of both of them.
This story in the Old Testament is a falsification and deception. Allah the Almighty revealed: "0 Children of Adam! Let not Satan deceive you, as he got your parents (Adam and Eve) out of Paradise, stripping them of their raiments; to show them their private parts. Verily he and Qabiluhu (his soldiers from the jinn or his tribe) see you from where you cannot see them. Verily, We made the devils protectors and helpers) for those who believe not. " Surah 7: 27
Adam had hardly finished eating when he felt his heart contract, and he was filled with pain, sadness, and shame. The surrounding atmosphere had changed and the internal music had stopped. He discovered that he and his wife were naked, so they both started cutting tree leaves with which to cover themselves.
Allah the Almighty addressed him: "Did I not forbid you that tree and tell you: Verily, Satan is an open enemy unto you?" They said: "Our Lord! We have wronged ourselves. If You forgive us not, and bestow not upon us Your Mercy, we shall certainly be of the losers." (Allah) said: "Get down, one of you an enemy to the other (i.e., Adam, Eve, and Satan, etc.). On earth will be a dwelling place for you and an enjoyment, - for a time." He said: "Therein you shall live, and therein you shall die, and from it you shall be brought out (i.e. resurrected)." Surah 7: 22-25
Again there are old stories about these events. Al-Hafez Ibn 'Asaker narrated that Allah commanded two angels to remove Adam from His holy proximity. So Gabriel stripped him of the crown on his head, and Michael took the diadem from his forehead. Adam thought that his punishment had been hastened and bowed down crying: "Forgiveness! Forgiveness!" So Allah asked: "Are you running away from Me?" Adam replied: "No, my Lord, but I am shy of You."
Abdul Rahman Ibn Amru Al-Awzaiy said that Adam spent one hundred years in Paradise. In another narration it was said that he spent sixty years. Ibn Asaker reported that Adam wept for sixty years for his loss of Paradise and seventy years for his mistake, and he wept for another seventy years when his son was killed.
