Dear brother Hamzeh, thank you for your patience in this discussion, and dear brother Samson, welcome in forum, and thanks for participating in discussion with me
I've been going through articles of brother Joseph in this topic, and in Quranic story of this event, and here are my conclusions, (which I can't guarantee are 100% correct, only God knows best, but I tried my best to understand as best as I could).
1)Universe (including earth) was created in stages. Seems that Earth was also meant to be a Paradise in stages - first, a small portion of it was Paradise, a garden in which were to be placed the two first creatures, and as they would multiply, the garden would expand, until the whole earth would turn into a Paradise.
2)God creates a creature from clay, to be placed in earth as a vicegerent. This creature, Adam, is created in the best of stature, and is given a free will. As a vicegerent of God, he would inherit the earth that would be a paradise - an eternal abode of felicity, where he wouldn't have to worry or grieve: no hunger, no thirst, no shame of nakedness, no illnesses, no death. God would provide for him all the best, eternally...as long as he proves to be exercising justly his free will. As long as he was proving to be worthy of being honored as a vicegerent on earth. And it was not a difficult task: one fruit was not to be consumed. He had everything good and delicious he wished for, he wouldn't feel the neediness of a fruit.
3)Our God informs us in the Quran that he is fully aware of his creatures: what they whisper inside their hearts, what they feel, what they wish for, what they dream for. So, He is aware that one of His creatures is developing jealousy and hatred towards Adam, and towards his exalted status. This creature, Iblees, the jinn created from smokeless fire, considers himself to be better than Adam, and therefore, more worthy of Adam's status. But God never punishes his creatures for a mere thought or feeling. Furthermore, if He would punish Iblees without him exposing himself, his perfect justice would be put in doubt in front of other creatures that would arguably be surprised and ask why (let us remember when angels were surprised ad asked God why was he creating a creature which would shed blood on earth).
4)God creates a situation where Iblees would expose himself. He gathers all of the creatures, and a command is given through angels:"Prostrate before Adam!". Iblees's pride couldn't bare it - his jealousy can't be hidden anymore, and he doesn't prostrate. God demands an explanation, and he answers "I'm better than him. You created me from fire, and him you created from clay!"Never would I prostrate to a human whom You created out of clay from an altered black mud."(7:12, 15:33). God's punishment is inevitable now, and Iblees is banished from Paradise. His hatred towards Adam and his progeny is even greater now, he doesn't have to be hidden enemy anymore, now he's an open enemy and swears vengeance. He asks God to reprieve him his punishment, for he will prove to God those very people that God punished him for, are the same that will disobey him like he(Iblees) did.
5)The place where Iblees was banished from was Paradise. Being in Paradise together with angels and other jinns, all of them would arguably have heard and known the command given to Adam not to go near the tree, because he would become a wrongdoer. And a wrongdoer loses the eternal abode in Paradise. His sufferings and death is inevitable, and one day his answerability about the way he used free will is also inevitable. Arrogance and narcissism always raise self-confidence - He is so confident he will make them wrongdoers that he asks God to reprieve him until the day they are raised from dead to answer to God for their choices. God reprieves him, and warns Adam and his spouse to beware of him, because he wants to expel them from Paradise.
6)Iblees starts immediately to work towards his goal. He knows that the forbidden fruit is the only chance he has, the only thing that could serve his purpose. So, he has to make them eat from it. How?
"Your Lord did not forbid you this tree except that you become angels or become of the immortal."(7:20). When we examine this verse, we can see something interesting in Iblees's words. As we know, angels are also creatures of the same God as us, but they have no physical body, they are very powerful (example: the way two of them destroyed the people of Lot), and they don't need to eat or drink like us humans. As to humans, they are of lesser power than angels, and they need food and drink, which was provided from God (ever since humanity exists), what made them somehow more dependent on God. By telling them that if they ate the fruit they would become 'like angels, or become of the immortals'', he was insinuating that they would become a type of immortals similar to angels: more powerful, and in no need of God's provisions of food and drink, which means more independence from God . He was instilling in them the greed for more than they were given - the same feelings he had in himself. He succeeded, and they ate the fruit. The consequences?:
"And We said, "Go down, [all of you], as enemies to one another, and you will have upon the earth a place of settlement and provision for a time."(2:36).This is where Adam and Eve's life appears for the first time as limited/finite. They had lost immortality and felicity - outside the Paradise they were going to face suffering, and finally death. But Allah accepted their repentance the moment they pleaded for forgiveness, so there was hope that they would regain the Paradise they lost - that depended from their obedience from then until their death. Allah promised to take care also for the progeny of Adam and Eve, that would be born in earth during this time, and that was not responsible for being outside the Paradise (they were affected by the choice of their parents, but they were not guilty of it, nauzubilah). So, since they were to be born in a life full of hardships, and since they would be even more vulnerable to Devil's traps then Adam and Eve, God would personally take care of them and give them a chance to get the Paradise that was originally meant for them too:
"We said, "Go down from it, all of you. And when guidance comes to you from Me, whoever follows My guidance - there will be no fear concerning them, nor will they grieve."(2:38).
"Descend from Paradise - all, [your descendants] being enemies to one another. And if there should come to you guidance from Me - then whoever follows My guidance will neither go astray nor suffer."(20:123).
It is up to our choice to follow our Lord's guidance (Quran), and to regain eternall life and happiness, and the Paradise that Devil swore we will lose.
As I said, these are solely the conclusions from my research on this topic, and an answer from brother Joseph would be extremely helpful, but anyways, in the end, God knows best.
