But [let them always remember that] if We lengthen a human being's days, We also cause him to decline in his powers [when he grows old]: will they not, then, use their reason? 68 And We did not give Prophet Muhammad, knowledge of poetry, nor is it befitting for him. It is not but a message and a clear Qur'an 69 that he may warn the living, and so that Judgement may be passed against the unbelievers. 70 Have they not seen how We have created for them of Our handiwork the cattle, so that they are their owners, 71 And We have subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 Benefits and (divers) drinks have they from them. Will they not then give thanks? 73 And they have appointed Gods other than Allah, that perhaps they may be helped! 74 They have not the power to help them: but they will be brought up (before Our Judgment-seat) as a troop (to be condemned). 75 So let not their speech grieve you. Indeed, We know what they conceal and what they declare. 76 Does man not see that We created him of a sperm drop, and lo! he is flagrantly contentious? 77 He questions Our Resurrection of him, but has forgotten his own creation. He has said, "Who will give life to the bones which have become ashes?" 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again. He has the best knowledge of all creatures. 79 "The same Who produces for you fire out of the green tree, when behold! ye kindle therewith (your own fires)! 80 Is not He Who created the heavens and the earth Able to create the like of them? Aye, that He is! for He is the All-Wise Creator, 81 when He decrees a thing, He need only say, "Be!" and it is. 82 Therefor Glory be to Him in Whose hand is the dominion over all things! Unto Him ye will be brought back. 83
