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 And We have not taught him poetry, nor is it meet for him; it is nothing but a reminder and a plain Quran, 69 To warn whosoever liveth, and that the word may be fulfilled against the disbelievers. 70 Have they not seen how We have created for them the cattle they master with Our Hands? 71 and that We have subjected them to men's will, so that some of them they may use for riding and of some they may eat, 72 And therein they have advantages and drinks; will they not then be grateful? 73 And yet they have taken gods, other than Allah, so that they might be helped! 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 So let not their speech, then, grieve you (O Muhammad SAW). Verily, We know what they conceal and what they reveal. 76 Doth not man see that it is We Who created him from sperm? yet behold! he (stands forth) as an open 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 who created you the first time. He has knowledge of every creation, 79 He who produces for you fire out of the green tree, so that, lo! you kindle [your fires] therewith." 80 Is, then, He who has created the heavens and the earth not able to create [anew] the like of those [who have died]? Yea, indeed - for He alone is the all-knowing Creator: 81 His command is only when He intends a thing that He says to it, "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
