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 instructed the (Prophet) in Poetry, nor is it meet for him: this is no less than a Message and a Qur'an making things clear: 69 to warn all who are truly alive, and to justify the word [God's verdict] against the deniers. 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 And We have subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 they also have other uses in them and drinks. What, will they not give thanks! 73 And yet they have taken gods, other than Allah, so that they might be helped! 74 They (the appointed Gods) cannot help them; and they and their armies will come (to Us), as captives. 75 So let not their speech grieve thee. Verily We! We know whatsoever they keep secret and whatsoever they make known. 76 Does not man see that We have created him from the small seed? Then lo! he is an open disputant. 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 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 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 them? Yea! and He is the Creator (of all), the Knower. 81 When He wills a thing He has only to say: "Be," and it is. 82 Therefore Purity is to Him in Whose Hand* is the control over all things and it is towards Him that you will be returned. (Used as a metaphor to mean Power). 83
