Surah Al-Imran, verse 106

يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ ۚ فَأَمَّا ٱلَّذِينَ ٱسْوَدَّتْ وُجُوهُهُمْ أَكَفَرْتُم بَعْدَ إِيمَـٰنِكُمْ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ ﴿١٠٦﴾

3:106 On the Day when some faces will turn bright while other faces will turn dark. As for those whose faces turn dark, [they will be told], “Did you disbelieve after having believed? Taste the punishment for your disbelief.”
