And We have certainly created you, [O Mankind], and given you [human] form. Then We said to the angels, “Prostrate to Adam”; so they prostrated, except for Iblees. He was not of those who prostrated.

 And [mention] when We said to the angels, “Prostrate to Adam,” and they prostrated, except for Iblees. He was of the jinn and departed from the command of his Lord. Then will you take him and his descendants as allies other than Me while they are enemies to you? Wretched it is for the wrongdoers as an exchange.

(20:116)

وَلَقَدْ صَدَّقَ عَلَيْهِمْ إِبْلِيسُ ظَنَّهُ فَاتَّبَعُوهُ إِلَّا فَرِيقًا مِنَ الْمُؤْمِنِينَ

 [God] said, “O Iblees, what prevented you from prostrating to that which I created with My hands? Were you arrogant [then], or were you [already] among the haughty?
