Al-A'raf - 7:12

قَالَ مَا مَنَعَكَ أَلاَّ تَسْجُدَ إِذْ أَمَرْتُكَ قَالَ أَنَاْ خَيْرٌ مِّنْهُ خَلَقْتَنِي مِن نَّارٍ وَخَلَقْتَهُ مِن طِينٍ
[7:12]
He said: What hindered you so that you did not prostrate when I commanded you? He said: I am better than he: Thou hast created me of fire, while him Thou didst create of dust.
(Allah) said: "What prevented thee from prostrating when I commanded thee?" He said: "I am better than he: Thou didst create me from fire, and him from clay."
He said: What hindered thee that thou didst not fall prostrate when I bade thee? (Iblis) said: I am better than him. Thou createdst me of fire while him Thou didst create of mud.
