Sura Āl-ʿImrān 3:106

يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ فَأَمَّا ٱلَّذِينَ ٱسْوَدَّتْ وُجُوهُهُمْ أَكَفَرْتُم بَعْدَ إِيمَٰنِكُمْ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ

yawma tabyaḍḍu wujūhun wa-taswaddu wujūhun fa-ammā lladhīna aswaddat wujūhuhum akafartum baʿda īmānikum fa-dhūqū l-ʿadhāba bi-mā kuntum takfurūna

On the Day when some faces will be (lit up with) white, and some faces will be (in the gloom of) black: To those whose faces will be black, (will be said): "Did ye reject Faith after accepting it? Taste then the penalty for rejecting Faith."
