مَثَلُهُمْ كَمَثَلِ ٱلَّذِى ٱسْتَوْقَدَ نَارًۭا فَلَمَّآ أَضَآءَتْ مَا حَوْلَهُۥ ذَهَبَ ٱللَّهُ بِنُورِهِمْ وَتَرَكَهُمْ فِى ظُلُمَٰتٍۢ لَّا يُبْصِرُونَ
Their likeness is as the likeness of one who kindleth fire, and when it sheddeth its light around him Allah taketh away their light and leaveth them in darkness, where they cannot see,
Surah Al-Baqara(2:17)
