Al-Isra' - 17:61

وَإِذْ قُلْنَا لِلْمَلآئِكَةِ اسْجُدُواْ لآدَمَ فَسَجَدُواْ إَلاَّ إِبْلِيسَ قَالَ أَأَسْجُدُ لِمَنْ خَلَقْتَ طِينًا
[17:61]
And when We said to the angels: Make obeisance to Adam; they made obeisance, but Iblis (did it not). He said: Shall I make obeisance to him whom Thou hast created of dust?
Behold! We said to the angels: "Bow down unto Adam": They bowed down except Iblis: He said, "Shall I bow down to one whom Thou didst create from clay?"
And 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?
