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 did not teach him (Muhammad) poetry, nor was he supposed to be a poet. It is only the word (of God) and the illustrious Quran 69 In order that it may warn him who is alive, and that the sentence may be justified on the infidels. 70 Do they not see that, among the things which Our hands have fashioned, We have created for them cattle of which they are the masters, 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 and may have [yet other] benefits from them, and [milk] to drink? Will they not, then, be grateful? 73 And take other gods apart from God that they may perhaps give them help. 74 It is not in their power to help them; but they (the worshippers) are unto them a host in arms. 75 So let not their speech grieve thee. Verily We! We know whatsoever they keep secret and whatsoever they make known. 76 Doth not man see that it is We Who created him from sperm? yet behold! he (stands forth) as an open adversary! 77 And he puts forth for Us a parable, and forgets his own creation. He says: "Who will give life to these bones when they have rotted away and became dust?" 78 Say thou: He shall quicken them Who brought them forth for the first time, and He is of every kind of creation the Knower! 79 [It is] He who made for you from the green tree, fire, and then from it you ignite. 80 Is not He who created the heavens and the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 His Being alone is such that when He wills a thing to be, He but says unto it, "Be" — and it is. 82 So glory be to Him, in whose hand is the dominion of everything, and unto whom you shall be returned. 83
