Surah Al-Hashr, ayah 19

وَلَا تَكُونُواْ كَٱلَّذِينَ نَسُواْ ٱللَّهَ فَأَنسَىٰهُمۡ أَنفُسَهُمۡۚ أُوْلَٰٓئِكَ هُمُ ٱلۡفَٰسِقُونَ ١٩

Walā takūnū kalladhīna nasullāha fa ansāhum anfusahum ulā'ika humul-fāsiqūn

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