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 by which he may warn those who are living and may let the words of God come true against the unbelievers. 70 Do they not see that We have created for them from what Our hands have made, grazing livestock, and [then] they are their owners? 71 We have subjected the cattle to them so that some of them they ride and eat the flesh of others. 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 And yet they have taken gods, other than Allah, so that they might be helped! 74 they are unable to succour their devotees, even though to them they may [appear to] be hosts drawn up [for succour]. 75 Therefore let not their speech grieve you; surely We know what they do in secret and what they do openly. 76 And did not man see that We have created him from a drop of semen? Yet he is an open quarreller! 77 producing arguments against Us, and forgetting his own creation. He asks, "Who can give life back to bones after they have rotted away?" 78 Say: 'He shall quicken them, who originated them the first time; He knows all creation, 79 who has made for you out of the green tree fire and lo, from it you kindle.' 80 Is He who created the heavens and the earth unable to create their like? Yes, indeed, He is the Creator, the Knower. 81 His command is only when He intends a thing that He says to it, "Be," and it is. 82 Wherefore hallowed be He in whose hand is the governance of everything, and unto whom ye shall be returned. 83
