يَّوْمَ تَبْيَضُّ وُجُوْهٌ وَّتَسْوَدُّ وُجُوْهٌ ۚ فَاَمَّا الَّذِيْنَ اسْوَدَّتْ وُجُوْهُهُمْۗ اَ كَفَرْتُمْ بَعْدَ اِيْمَانِكُمْ فَذُوْقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُوْنَ ( آل عمران: ١٠٦ )
Yawma tabyaddu wujoohunw wa taswaddu wujooh; faammal lazeenas waddat wujoohum akafartum ba'da eemaanikum fazooqul 'azaaba bimaa kuntum takfuroon (ʾĀl ʿImrān 3:106)
Sahih International:
On the Day [some] faces will turn white and [some] faces will turn black. As for those whose faces turn black, [to them it will be said], "Did you disbelieve [i.e., reject faith] after your belief? Then taste the punishment for what you used to reject." (Ali 'Imran [3] : 106)
1 Mufti Taqi Usmani
on a day when some faces shall turn bright, and some faces shall turn dark. As for those whose faces turn dark, (they shall be questioned): “Did you disbelieve after you had accepted the Faith? Now taste the punishment, because you used to disbelieve.”
