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 have not taught him poetry, nor is it meet for him; it is nothing but a reminder and a plain Quran, 69 to warn all who are truly alive, and to justify the word [God's verdict] against the deniers. 70 Have they not seen how We have created for them the cattle they master with Our Hands? 71 We have subjected these to them, so that some may be used for riding and some for food, 72 And they have therefrom other benefits and drinks. Will they not then give thanks? 73 They have set up other gods besides God, hoping to be helped by them, 74 They are not able to help them, and they [themselves] are for them soldiers in attendance. 75 So do not let their sayings grieve you. Surely, We have knowledge of what they hide and all that they reveal. 76 Does man not see that We created him of a sperm drop, and lo! he is flagrantly contentious? 77 And he has struck for Us a similitude and forgotten his creation; he says, 'Who shall quicken the bones when they are decayed?' 78 Say, "He who brought them into being in the first instance will give them life again: He has knowledge of every type of creation: 79 Who gave you fire from a green tree, with which you ignite the flame." 80 And is it not possible for the One Who created the heavens and the earth to create the likes of them? It is surely possible, why not? And He is the Great Creator, the All Knowing of everything. 81 His affair, when He intendeth a thing, is only that He saith unto it: be, and it becometh. 82 So glory to Him in Whose hands is the dominion of all things: and to Him will ye be all brought back. 83
