فَأَزَلَّهُمَا الشَّيْطَانُ عَنْهَا فَأَخْرَجَهُمَا مِمَّا كَانَا فِيهِ ۖ وَقُلْنَا اهْبِطُوا بَعْضُكُمْ لِبَعْضٍ عَدُوٌّ ۖ وَلَكُمْ فِي الْأَرْضِ مُسْتَقَرٌّ وَمَتَاعٌ إِلَىٰ حِينٍ (36)
(2:36) After a time Satan tempted them with that tree to disobey. Our Command and brought them out of the state they were in, and We decreed, "Now, go down all of you from here; you are enemies of one another. *50 Henceforth you shall dwell and provide for yourselves on the Earth for a specified period."
*50). This means that Satan is the enemy of man, and vice versa. That Satan is the enemy, of man is obvious enough, for he tries to drive him off the course of obedience to God and leads him to perdition, but one might wonder how man could be referred to as the enemy of Satan. The fact is that man's essential humanity makes this enmity incumbent upon him. Man, however, is often deceived by Satan and befriends him owing to the temptations that he holds out to him. This kind of friendship does not mean that the basic, irreconcilable clash of interests between man and Satan has been resolved. It only means that one of the two (Satan) has defeated and successfully trapped the other (man).
