Al 'Imran, 106 Ayah
3:106
يَوۡمَ تَبۡيَضُّ وُجُوهٞ وَتَسۡوَدُّ وُجُوهٞۚ فَأَمَّا ٱلَّذِينَ ٱسۡوَدَّتۡ وُجُوهُهُمۡ أَكَفَرۡتُم بَعۡدَ إِيمَٰنِكُمۡ فَذُوقُواْ ٱلۡعَذَابَ بِمَا كُنتُمۡ تَكۡفُرُونَ ١٠٦
Yawma Tabyađđu Wujūhun Wa Taswaddu Wujūhun ۚ Fa'ammā Al-Ladhīna Aswaddat Wujūhuhum 'Akafartum Ba`da 'Īmānikum Fadhūqū Al-`Adhāba Bimā Kuntum Takfurūna
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 after your belief? Then taste the punishment for what you used to reject."
