Overall meaning :
The Almighty says, pointing out Satan’s bitter enmity towards Adam and warning his descendants against taking him and his progeny for friends and supporters: Tell people, Muhammad, of the time when We commanded the angels to prostrate themselves before Adam as an act of honour and respect for him. They all fell prostrate, except for Iblees. He was of the jinn, and, prompted by pride and envy, he refused to prostrate when ordered to do so, thereby disobeying Allah’s command. Would you then, descendants of Adam, take him and his progeny as your guardians and supporters, by obeying them and disobeying Me, when they are your enemies that strive to lead you astray?! Evil indeed is the alternative the wrongdoers have chosen instead of the All-Compassionate God!
Then, mentioning one aspect of His perfect knowledge and power, He says: I did not call Satan and his descendants to witness the creation of the heavens and the earth, so that I would seek their help, nor to witness the creation of one another—for I have created all that by Myself without any helper whatsoever; nor would I ever need to take as assistants in any of My affairs those who lead people astray—and anyone else, for that matter.
