The story of the descent to Earth

 The story of the descent to Earth is a continuation of the story of creation of Adam. After Allah created Adam, He created His wife Eve (Hawwa) from one of his ribs, so all humans originate from a single soul, which is Adam, from whom Eve was created and from Adam and Eve, all humans were created as Allah says in Aya (1) of Surat Alnisa' {O people! Fear your Lord, the One who created you from one soul and created from it its spouse, and dispersed from both of them many men and women, and Fear Allah through whom you ask one another and the wombs, indeed, Allah is Observer over you}, and Allah's Messenger (PBUH) said in narration of Abu Hurayrah: "Woman has been created from a rib, and will in no way be straightened for you, so if you wish to benefit by her, benefit by her while crookedness remains in her, and if you attempt to straighten her, you will break her, and breaking her is divorcing her" (Sahih Muslim 1467 b). 
   

 Allah honored Adam by commanding the Angels to prostrate before him, so they all prostrated except for Iblis, then Allah honored Adam again by placing him and his wife Eve in Paradise as mentioned in Ayat (35-39) of Surat Albaqarah {And We said O Adam! Dwell you and your wife in Paradise, and Eat you both therefrom in abundance wherever you both wish, and Do not approach this tree lest you both will be of the wrongdoers, but Satan caused both of them to slip from it and drove out both of them from what they were in, and We said Go down, being enemies to one another, and for you on the earth there is a place of residence and an enjoyment for a time, then Adam received from His Lord words, and He turned to Him, indeed, He is Ever accepting of repentance, the Most Merciful, We said Go down from it, all of you, and if there should come to you a guidance from Me, then whoever follows My guidance, there will be no fear for them, nor will they grieve, and those who disbelieve and deny Our signs, those are the companions of the Fire, they will abide therein forever}.

 So Allah commanded Adam and his wife Eve to dwell in Paradise, and allowed both of them to eat from its fruits in abundance from wherever they wished, and forbade both of them from approaching the fruit of a certain tree lest both of them will be among the wrongdoers who wrong themselves by disobeying the command of their Lord. But Satan caused Adam and Eve to slip from it as Satan deceived Adam saying O Adam shall I direct you to the tree of eternity and a kingdom that will not deteriorate as Allah has stated in Aya (120) Surat Ta Ha, so Adam and Eve ate from the forbidden tree and disobeyed the command of Allah, and when they tasted it, their private parts became apparent to both of them, then they both began to cover their private parts by the leaves of Paradise, then Allah called Adam and Eve saying Did I not forbid you both from that tree and say to both of you that Satan is a clear enemy to both of you? as mentioned in Aya (22) of Surat Ala'raf. Thereupon, Allah ordered Adam, Eve, and Satan to descend from Paradise to the Earth, all of them, they are enemies to one another, Adam and His offspring and Satan and His offspring, and Allah assured them that for them on the earth is a place of residence on the surface of the earth during their lives, and in its soil after their death, and an enjoyment in the worldly life, so Allah will let them enjoy the worldly life and its pleasures of eating, drinking, clothing, talking, companionship and other things for an appointed time that only Allah knows.

 When Adam disobeyed the command of Allah and ate from the forbidden tree, he had no determination to disobey Allah and follow Satan as Allah has stated in Aya (115) of Surat Ta Ha, so Allah taught Adam words of repentance, and Adam received them from His Lord and repented to Allah, then Allah accepted His repentance and turned to Him in mercy and forgiveness by accepting and saying these words, and these words were mentioned in Aya (23) of Surat Ala'raf {Both of them said Our Lord, we have wronged ourselves, and if You do not forgive us and have mercy upon us, we will surely be among the losers}. Then Allah assured that He is Ever accepting of repentance, Most Merciful for those who repent and give up the sins. Allah then ordered Adam, Eve, and Satan to descend from Paradise to the earth, all of them, and Allah assures them that if there should come to them a guidance from Him through the Messengers, the Prophets, and the Scriptures, then whoever follows Allah's guidance by following His Messengers and adhering to His Scriptures , there will be no fear for him for what he will face later and he will not grieve for what he missed before. 

  But as for those who disbelieve in Allah, His Messengers, and His Scriptures, and denied Allah's signs with which He sent His Messengers in order to indicate the truthfulness of what they brought from their Lord, then those are the companions of Hellfire, abiding therein forever; Because disbelief and denial are of the unforgivable sins, and Allah's Messenger (PBUH) said in narration of Abu Sa'id: "The inhabitants of the Fire who are doomed to it, they would neither die nor live in it, but the people whom the Fire would afflict on account of their sins, or He said on account of their misdeeds, He would cause them to die till they would be turned into charcoal, then they would be granted intercession and would be brought into groups and would be spread on the rivers of Paradise, then it would be said O inhabitants of Paradise, Pour water over them, then they would sprout forth like the sprouting of seeds in the silt carried by flood" (Sahih Muslim 185 a).
