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 (Muhammad SAW) poetry, nor is it meet for him. This is only a Reminder and a plain Quran. 69 That it may warn him who would have life, and (that) the word may prove true against the unbelievers. 70 Have they not seen how We have created for them the cattle they master with Our Hands? 71 We have subdued these to them, and some of them they ride and some of them they eat; 72 and may have [yet other] benefits from them, and [milk] to drink? Will they not, then, be grateful? 73 Yet they have taken, apart from God, gods; haply they might be helped. 74 (But) they shall not be able to assist them, and they shall be a host brought up before them. 75 Muhammad, let not their words annoy you. We certainly know whatever they conceal or reveal. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 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 will give life to them Who brought them into existence at first, and He is cognizant of all creation 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 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 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
