أَوۡ كَظُلُمَٰتٖ فِي بَحۡرٖ لُّجِّيّٖ يَغۡشَىٰهُ مَوۡجٞ مِّن فَوۡقِهِۦ مَوۡجٞ مِّن فَوۡقِهِۦ سَحَابٞۚ ظُلُمَٰتُۢ بَعۡضُهَا فَوۡقَ بَعۡضٍ إِذَآ أَخۡرَجَ يَدَهُۥ لَمۡ يَكَدۡ يَرَىٰهَاۗ وَمَن لَّمۡ يَجۡعَلِ ٱللَّهُ لَهُۥ نُورٗا فَمَا لَهُۥ مِن نُّورٍ

Aw kazulumaatin fee bahril lujjiyyiny yaghshaahu mawjun min fawqihee mawjun min fawqihee sahaab; zulumatun ba'duhaa fawqa ba'din izaaa akhraja yadahoo lam yakad yaraahaa wa man lam yaj'alil laahu lahoo nooran famaa lahoo min noor

Or (the Unbelievers' state) is like the depths of darkness in a vast deep ocean, overwhelmed with billow topped by billow, topped by (dark) clouds: depths of darkness, one above another: if a man stretches out his hands, he can hardly see it! for any to whom Allah giveth not light, there is no light!

— An-Nur (ٱلنُّور), 24:40
