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 poetry; it is not seemly for him. It is only a Remembrance and a Clear Koran, 69 to the end that it may warn everyone who is alive [of heart,] and that the word [of God] may bear witness against all who deny the truth. 70 Observe they not that We have created for them, of that which Our hands have worked, cattle: so that they are their owners. 71 And have subjected the animals for them, so they ride some animals and eat some? 72 some for milk to drink and some from which other benefits may be received? Will they not be grateful? 73 And they have taken beside Allah gods, hoping that haply they may be succoured. 74 They cannot help them, but they will be brought forward as a troop against those who worshipped them (at the time of Reckoning). 75 Let not their words grieve you. Surely We know all things about them, what they conceal and what they reveal. 76 Has the human not seen how We created him from a drop (of sperm)? Yet he is a clear opponent. 77 And he invents an example for Us, while forgetting his own creation, saying, “Who is such that can revive the bones when they have completely 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 [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 earth, able to create the like of them? Yes indeed; He is the All-creator, the All-knowing. 81 His command is only when He intends a thing that He says to 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
