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 to warn all who are truly alive, and to justify the word [God's verdict] against the deniers. 70 Observe they not that We have created for them, of that which Our hands have worked, cattle: so that they are their owners. 71 And have subjected the animals for them, so they ride some animals and eat some? 72 some for milk to drink and some from which other benefits may be received? Will they not be grateful? 73 They set up deities apart from Allah, hoping that they will receive help from them. 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 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 IS MAN, then, not aware that it is We who create him out of a [mere] drop of sperm - whereupon, lo! he shows himself endowed with the power to think and to argue? 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 78 Say: "He who brought them into being in the first instance will give them life [once again,] seeing that He has full knowledge of every act of creation: 79 He who produces fire for you from green trees and from this you kindle fire." 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 His Being alone is such that when He wills a thing to be, He but says unto it, "Be" — and it is. 82 So Glorified is He and Exalted above all that they associate with Him, and in Whose Hands is the dominion of all things, and to Him you shall be returned. 83
