Will you then not understand? 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 that he may warn him who is alive and establish an argument against those that deny the Truth. 70 Have they not seen what We have created from the labor of Our own hands? We have given them cattle. 71 We have subjected the cattle to them so that some of them they ride and eat the flesh of others. 72 And they derive other advantages and drinks from them. Even then they do not offer thanks, 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 74 They (the appointed Gods) cannot help them; and they and their armies will come (to Us), as captives. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 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 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 who brought them into being in the first instance will give them life again: He has knowledge of every type of creation: 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is not He Who created the heavens and the earth Able to create the like of them? Aye, that He is! for He is the All-Wise 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
