Surat Aal-i-Imraan (The Family of Imraan) - آل عمران

وَلَا تَكُونُوا۟ كَٱلَّذِينَ تَفَرَّقُوا۟ وَٱخْتَلَفُوا۟ مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْبَيِّنَٰتُ وَأُو۟لَٰٓئِكَ لَهُمْ عَذَابٌ عَظِيمٌ ﴿١٠٥﴾ يَوْمَ تَبْيَضُّ وُجُوهٌ وَتَسْوَدُّ وُجُوهٌ فَأَمَّا ٱلَّذِينَ ٱسْوَدَّتْ وُجُوهُهُمْ أَكَفَرْتُم بَعْدَ إِيمَٰنِكُمْ فَذُوقُوا۟ ٱلْعَذَابَ بِمَا كُنتُمْ تَكْفُرُونَ﴿١٠٦﴾ وَأَمَّا ٱلَّذِينَ ٱبْيَضَّتْ وُجُوهُهُمْ فَفِى رَحْمَةِ ٱللَّهِ هُمْ فِيهَا خَٰلِدُونَ﴿١٠٧﴾

And be not like those who became divided and disagreed after clear arguments had come to them, and these it is that shall have a grievous chastisement. On the day when (some) faces shall turn white and (some) faces shall turn black; then as to those whose faces turn black: Did you disbelieve after your believing? Taste therefore the chastisement because you disbelieved. And as to those whose faces turn white, they shall be in Allah's mercy; in it they shall-abide.
