Surah Al-Hashr, Verse 19

وَلَا تَكُونُواْ كَٱلَّذِينَ نَسُواْ ٱللَّهَ فَأَنسَىٰهُمۡ أَنفُسَهُمۡۚ أُوْلَٰٓئِكَ هُمُ ٱلۡفَٰسِقُونَ١٩

walā takūnū ka-alladhīna nasū l-laha fa-ansāhum anfusahum ulāika humu l-fāsiqūna

And be not like those who forgot Allāh, so He made them forget themselves. Those are the defiantly disobedient.
