Surah An-Nur (The Light), Verse 40

اَوْ كَظُلُمٰتٍ فِیْ بَحْرٍ لُّجِّیٍّ یَّغْشٰىهُ مَوْجٌ مِّنْ فَوْقِهٖ مَوْجٌ مِّنْ فَوْقِهٖ سَحَابٌ ظُلُمٰتٌ بَعْضُهَا فَوْقَ بَعْضٍ اِذَاۤ اَخْرَجَ یَدَهٗ لَمْ یَكَدْ یَرٰىهَا وَمَنْ لَّمْ یَجْعَلِ اللّٰهُ لَهٗ نُوْرًا فَمَا لَهٗ مِنْ نُّوْرٍ 

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!”

Quran 24:40 (Yusuf Ali Translation)
