An-Nur 24:40 او كظلمات في بحر لجي يغشاه موج من فوقه موج من فوقه سحاب ظلمات بعضها فوق بعض اذا اخرج يده لم يكد يراها ومن لم يجعل الله له نورا فما له من نور ٤٠

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!
