The story of Adam is one of my favorite stories in the quran. Why? Because, Allah gives us a little history of what happened in heaven before man was created, and up until he was sent down to earth as a vicegerent. A vicegerent is a person exercising delegated power on behalf of a sovereign or ruler. We were created specifically for earth and we were not sent to earth until we were ready to make our own decisions. Adam approached the forbidden tree based on his own decision, no one forced him. Adam even gets words of inspiration from Allah and is forgiven before he is sent to earth, as was planned before his creation. Allah knows best, but below are his words from the Quran found in Suratul Al Baqarah. Take the time to Read and process these very heavy words.
2:30 Behold, thy Lord said to the angels: "I will create a vicegerent on earth." They said: "Wilt Thou place therein one who will make mischief therein and shed blood?- whilst we do celebrate Thy praises and glorify Thy holy (name)?" He said: "I know what ye know not."
2:31 And He taught Adam the nature of all things; then He placed them before the angels, and said: "Tell me the nature of these if ye are right."
2:32 They said: "Glory to Thee, of knowledge We have none, save what Thou Hast taught us: In truth it is Thou Who art perfect in knowledge and wisdom."
2:33 He said: "O Adam! Tell them their natures." When he had told them, Allah said: "Did I not tell you that I know the secrets of heaven and earth, and I know what ye reveal and what ye conceal?"
2:34 And behold, We said to the angels: "Bow down to Adam" and they bowed down. Not so Iblis: he refused and was haughty: He was of those who reject Faith.
Iblis is further described of his nature in Surah Alkhalf chapter 18.
We said to the angels, "Bow down to Adam": They bowed down except
Iblis. He was one of the Jinns, and he broke the Command of his Lord.
Will ye then take him and his progeny as protectors rather than Me? And
they are enemies to you! Evil would be the exchange for the wrong-doers!
2:35 We said: "O Adam! dwell thou and thy wife in the Garden; and eat of the bountiful things therein as (where and when) ye will; but approach not this tree, or ye run into harm and transgression."
2:36 Then did Satan make them slip from the (garden), and get them out of the state (of felicity) in which they had been. We said: "Get ye down, all (ye people), with enmity between yourselves. On earth will be your dwelling-place and your means of livelihood - for a time."
2:37 Then learnt Adam from his Lord words of inspiration, and his Lord Turned towards him; for He is Oft-Returning, Most Merciful.
2:38 We said: "Get ye down all from here; and if, as is sure, there comes to you Guidance from me, whosoever follows My guidance, on them shall be no fear, nor shall they grieve.
2:39 "But those who reject Faith and belie Our Signs, they shall be companions of the Fire; they shall abide therein."
