Surah Al-A'raf — Ayah 12 (7:12)
قَالَ مَا مَنَعَكَ أَلَّا تَسۡجُدَ إِذۡ أَمَرۡتُكَۖ قَالَ أَنَا۠ خَيۡرٞ مِّنۡهُ خَلَقۡتَنِي مِن نَّارٖ وَخَلَقۡتَهُۥ مِن طِينٖ ١٢
English translation (Saheeh International)
[Allāh] said, "What prevented you from prostrating when I commanded you?" [Satan] said, "I am better than him. You created me from fire and created him from clay [i.e., earth]."
Brief commentary
Allah asked Satan rebuking him: 'What stopped you from following My command to bow down to Adam?' Satan said: 'What prevented me is that I am better than Adam: You created me from fire and Adam from mud, and fire is greater then mud.'
