Surah Al-Anbya — Ayah 29 (21:29)
۞ وَمَن يَقُلۡ مِنۡهُمۡ إِنِّيٓ إِلَٰهٞ مِّن دُونِهِۦ فَذَٰلِكَ نَجۡزِيهِ جَهَنَّمَۚ كَذَٰلِكَ نَجۡزِي ٱلظَّٰلِمِينَ ٢٩
English translation (Saheeh International)
And whoever of them should say, "Indeed, I am a god besides Him" - that one We would recompense with Hell. Thus do We recompense the wrongdoers.
Brief commentary
And for argument’s sake, whoever amongst the angels were to say: “I am a god besides Allah”, I will punish him for what he says with Hellfire on the Day of Judgment, staying therein forever. And with this kind of punishment I punish those who are unjust by disbelieving and associating partners with Allah.
