There appears to be a pattern in the Quran where it gives the name Iblees ( إِبْلِيسَ) to Satan before he defied God’s commandment to fall prostrate before Adam, and after his exposure, he is referred to as Satan ( l-Shaitan / ٱلشَّيْطَـٰن). The name Iblees occurs 11 times in the Quran and shares the same root as “ba-lam-siin” ( ب ل س), which has the derivative meaning of “despair.”
2:33 He said, “O Adam, tell them their names.” When he told them their names, He said, “Did I not tell you that I know the secrets of the heavens and the earth? I know what you declare, and what you conceal.” 2:34 When we said to the angels, “Fall prostrate before Adam,” they fell prostrate, except Iblees ( إِبْلِيسَ); he refused, was too arrogant, and a disbeliever. 2:35 We said, “O Adam, live with your wife in Paradise, and eat therefrom generously, as you please, but do not approach this tree, lest you sin.” 2:36 But the de vil ( l-shayṭānu / ٱلشَّيْطَـٰنُ) duped them, and caused their eviction therefrom. We said, “Go down as enemies of one another. On Earth shall be your habitation and provision for awhile.”
7:11 We created you, then we shaped you, then we said to the angels, “Fall prostrate before Adam.” They fell prostrate, except Iblees ( إِبْلِيسَ); he was not with the prostrators. 7:12 He said, “What prevented you from prostrating when I ordered you?” He said, “I am better than he; You created me from fire, and created him from mud.” He said, “Therefore, you must go down, for you are not to be arrogant here. Get out; you are debased.” He said, “Grant me a respite, until the Day of Resurrection.” He said, “You are granted a respite.” He said, “Since You have willed that I go astray, I will skulk for them on Your straight path. “I will come to them from before them, and from behind them, and from their right, and from their left, and You will find that most of them are unappreciative.” He said, “Get out therefrom, despised and defeated. Those among them who follow you, I will fill Hell with you all. “As for you, Adam, dwell with your wife in Paradise, and eat therefrom as you please, but do not approach this one tree, lest you fall in sin.” The devil ( l-shayṭānu / ٱلشَّيْطَـٰنُ) whispered to them, in order to reveal their bodies, which were invisible to them. He said, “Your Lord did not forbid you from this tree, except to prevent you from becoming angels, and from attaining eternal existence.” He swore to them, “I am giving you good advice.” He thus duped them with lies. As soon as they tasted the tree, their bodies became visible to them, and they tried to cover themselves with the leaves of Paradise. Their Lord called upon them: “Did I not enjoin you from that tree, and warn you that the devil ( l-shayṭāna / ٱلشَّيْطَـٰنَ) is your most ardent enemy?” They said, “Our Lord, we have wronged our souls, and unless You forgive us and have mercy on us, we will be losers.” He said, “Go down as enemies of one another. On earth shall be your habitation and provision for awhile.” He said, “On it you will live, on it you will die, and from it you will be brought out.” O children of Adam, we have provided you with garments to cover your bodies, as well as for luxury. But the best garment is the garment of righteousness. These are some of GOD’s signs, that they may take heed. O children of Adam, do not let the devil ( l-shayṭānu / ٱلشَّيْطَـٰنُ) dupe you as he did when he caused the eviction of your parents from Paradise, and the removal of their garments to expose their bodies. He and his tribe see you, while you do not see them. We appoint the devils as companions of those who do not believe.
