Has there not been over Man a long period of Time, when he was nothing - (not even) mentioned?Verily We created Man from a drop of mingled sperm, in order to try him: So We gave him (the gifts), of Hearing and Sight.We showed him the Way: whether he be grateful or ungrateful (rests on his will).For the Rejecters we have prepared chains, yokes, and a blazing Fire.[76.1-4]
