Surah Al-Anbya 21:29

۞ وَمَن يَقُلْ مِنْهُمْ إِنِّىٓ إِلَـٰهٌ مِّن دُونِهِۦ فَذَٰلِكَ نَجْزِيهِ جَهَنَّمَ ۚ كَذَٰلِكَ نَجْزِى ٱلظَّـٰلِمِينَ

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.

Translation: Saheeh International

Tafsir

And should any of them say ‘I am a god besides Him’ that is besides God in other words a god other than Him — and this is Iblīs who summoned others to worship his soul and commanded that it be obeyed — such a one We will requite with Hell. Thus in the same way that We requite him We requite wrong-doers idolaters.
