And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.

So when they neglected what they had been reminded of, We delivered those who forbade evil and We overtook those who were unjust with an evil chastisement because they transgressed.

And when We said to the angels: Make obeisance to Adam; they made obeisance but Iblis (did it not). He was of the jinn, so he transgressed the commandment of his Lord. What! would you then take him and his offspring for friends rather than Me, and they are your enemies? Evil is (this) change for the unjust.
