سورة آل عمران

يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ ۚ فَأَمَّا الَّذِينَ اسْوَدَّتْ وُجُوهُهُمْ أَكَفَرْتُمْ بَعْدَ إِيمَانِكُمْ فَذُوقُوا الْعَذَابَ بِمَا كُنْتُمْ تَكْفُرُونَ ﴿١٠٦﴾

Surah Aali 'Imran

106. On the Day when faces whiten and faces blacken. As for those whose faces blacken: “Did you disbelieve after having believed?” So taste the punishment for having disbelieved.
