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 (Muhammad) to versify, nor is it worthy of him. This is nothing but a reminder and illuminating discourse, 69 In order that it may warn him who is alive, and that the sentence may be justified on the infidels. 70 Are they, then, not aware that it is for them that We have created, among all the things which Our hands have wrought, the domestic animals of which they are [now] masters? 71 Whom We made subservient to them so that some of them they ride and some they eat? 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 74 (But) they shall not be able to assist them, and they shall be a host brought up before them. 75 So let not their speech grieve you. Indeed, We know what they conceal and what they declare. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 77 And he presents for Us an example and forgets his [own] creation. He says, "Who will give life to bones while they are disintegrated?" 78 Say, "He will give them life who produced them the first time; and He is, of all creation, Knowing." 79 He, Who produces for you fire out of the green tree, when behold! You 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 Verily, His Command, when He intends a thing, is only that He says to it, "Be!" and it is! 82 So glory to Him in Whose hands is the dominion of all things: and to Him will ye be all brought back. 83
