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 We have not taught him (Prophet Muhammad) poetry, nor does it become him. This is only a Remembrance and a Clear Holy Reading (Koran) 69 That it may warn him who would have life, and (that) the word may prove true against the unbelievers. 70 Do they not see Our handiwork: We created for them cattle which they own? 71 And We have subdued them unto them so that some of them they have for riding and some they eat. 72 And they have therefrom other benefits and drinks. Will they not then give thanks? 73 And they have taken gods besides Allah that they may be helped. 74 They (the appointed Gods) cannot help them; and they and their armies will come (to Us), as captives. 75 So do not let their sayings grieve you. Surely, We have knowledge of what they hide and all that they reveal. 76 Does not man see We created him from a drop of semen? Even then he becomes an open contender, 77 producing arguments against Us, and forgetting his own creation. He asks, "Who can give life back to bones after they have rotted away?" 78 Say: “He Who first brought them into being will quicken them; He knows well about every kind of creation; 79 He has created fire for you out of the green tree from which you can kindle other fires. 80 Is not He who created the heavens and the earth able to create the like of these? Yea! He is the Supreme Creator, the Knower. 81 His command is only when He intends a thing that He says to it, "Be," and it is. 82 Wherefore hallowed be He in whose hand is the governance of everything, and unto whom ye shall be returned. 83
