Amatul Rahmân Omer:
Or (the deeds of the disbelievers are) like thick utter darkness of the fathomless deep sea, waves on top of which there are higher waves covering its surface which is overcast by clouds. These are (layers of) darkness (piled) one upon the other (as opposed to light upon light for the believers) so that a person, however much he may try, can hardly see his hand when he holds it out. Indeed, there is no light at all for the person whom Allâh gives no light.
