QS. An-Nur [24:40]

aw kazhulumaatin fii bahrin lujjiyyin yaghsyaahu mawjun min fawqihi mawjun min fawqihi sahaabun zhulumaatun ba'dhuhaa fawqa ba'dhin idzaa akhraja yadahu lam yakad yaraahaa waman lam yaj'ali allaahu lahu nuuran famaa lahu min nuurin

Or [they are] like darknesses within an unfathomable sea which is covered by waves, upon which are waves, over which are clouds - darknesses, some of them upon others. When one puts out his hand [therein], he can hardly see it. And he to whom Allah has not granted light - for him there is no light. [40]
