أَوْ كَظُلُمَٰتٍۢ فِى بَحْرٍۢ لُّجِّىٍّۢ يَغْشَىٰهُ مَوْجٌۭ مِّن فَوْقِهِۦ مَوْجٌۭ مِّن فَوْقِهِۦ سَحَابٌۭ ۚ ظُلُمَٰتٌۢ بَعْضُهَا فَوْقَ بَعْضٍ إِذَآ أَخْرَجَ يَدَهُۥ لَمْ يَكَدْ يَرَىٰهَا ۗ وَمَن لَّمْ يَجْعَلِ ٱللَّهُ لَهُۥ نُورًۭا فَمَا لَهُۥ مِن نُّورٍ
Or as darkness on a vast, abysmal sea. There covereth him a wave, above which is a wave, above which is a cloud. Layer upon layer of darkness. When he holdeth out his hand he scarce can see it. And he for whom Allah hath not appointed light, for him there is no light.
Surah An-Noor(24:40)
