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 (Muhammad) poetry, nor is it meet for him. This is naught else than a Reminder and a Lecture making plain, 69 that he may warn him who is alive and establish an argument against those that deny the Truth. 70 Do they not see that We have created cattle for them, out of what Our hands have wrought, so they are their masters? 71 We have subdued these to them, and some of them they ride and some of them they eat; 72 And therein they have advantages and drinks; will they not then be grateful? 73 They have set up other gods besides God, hoping to be helped by them, 74 They will not be able to help them and will be brought (to Us) as their levied troops. 75 So let not their speech, then, grieve you (O Muhammad SAW). Verily, We know what they conceal and what they reveal. 76 Does man not see that We created him of a sperm drop, and lo! he is flagrantly contentious? 77 And he hath coined for Us a similitude, and hath forgotten the fact of his creation, saying: Who will revive these bones when they have rotted away? 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 Who giveth you out of the green tree fire, and lo! ye kindle therewith. 80 Is not He Who created the heavens and the earth able to create the like of them? Yea! and He is the Creator (of all), the Knower. 81 His affair, when He intendeth a thing, is only that He saith unto it: be, and it becometh. 82 So Glorified is He and Exalted above all that they associate with Him, and in Whose Hands is the dominion of all things, and to Him you shall be returned. 83
