Refusing to bow to Adam

Except Iblees, he refused to be among those who bowed.

15:31Save Iblis. He refused to be among the prostrate.

17:61And when We said unto the angels: Fall down prostrate before Adam and they fell prostrate all save Iblis, he said: Shall I fall prostrate before that which Thou hast created of clay?

18:50And (remember) when We said unto the angels: Fall prostrate before Adam, and they fell prostrate, all save Iblis. He was of the jinn, so he rebelled against his Lord's command. Will ye choose him and his seed for your protecting friends instead of Me, when they are an enemy unto you? Calamitous is the exchange for evil-doers.
