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 did not teach him (to wit, the Messenger) poetry and it does not behove him. This is none but an Admonition, and a Clear Book 69 To warn whosoever liveth, and that the word may be fulfilled against the disbelievers. 70 Do they not see Our handiwork: We created for them cattle which they own? 71 We have subjected these to them, so that some may be used for riding and some for food, 72 And they derive other advantages and drinks from them. Even then they do not offer thanks, 73 And they have appointed Gods other than Allah, that perhaps they may be helped! 74 Those deities can render them no help. Yet these devotees act as though they were an army in waiting for them. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 76 Beholdest not man that We have created him from a sperm? Yet lo! he is a manifest disputer? 77 And he has struck for Us a similitude and forgotten his creation; he says, 'Who shall quicken the bones when they are decayed?' 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again. He has the best knowledge of all creatures. 79 [It is] He who made for you from the green tree, fire, and then from it you ignite. 80 Has He Who created the heavens and the earth no power to create the likes of them? Yes, indeed, He is the Superb Creator. 81 Whenever He wills a thing, He just commands 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
