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 So that he may warn him who is alive and feels, and justify the word against those who do not believe. 70 Have they not seen how We have created for them of Our handiwork the cattle, so that they are their owners, 71 And We have subdued them unto them so that some of them they have for riding and some they eat. 72 And therein they have advantages and drinks; will they not then be grateful? 73 Yet they take (for worship) gods other than Allah, (hoping) that they might be helped! 74 Instead, the disbelievers will be brought into the presence of God as the soldiers of the idols. 75 However, be not grieved by the sayings of those [who deny the truth]: verily, We know all that they keep secret as well as all that they bring into the open. 76 Beholdest not man that We have created him from a sperm? Yet lo! he is a manifest disputer? 77 And [now] he [argues about Us, and] thinks of Us in terms of comparison, and is oblivious of how he himself was created! [And so] he says, "Who could give life to bones that have crumbled to dust?" 78 Say, "He who brought them into being in the first instance will give them life again: He has knowledge of every type of creation: 79 Who hath appointed for you fire from the green tree, and behold! ye kindle from it. 80 Is not He who created the heavens and the earth able to create the like of these? Yea! He is the Supreme Creator, the Knower. 81 When He wills a thing He has only to say: "Be," and it is. 82 Therefor Glory be to Him in Whose hand is the dominion over all things! Unto Him ye will be brought back. 83
