Whoever reaches old age, We reverse in natural disposition. Do they not have sense (to see)? 68 And We did not give Prophet Muhammad, knowledge of poetry, nor is it befitting for him. It is not but a message and a clear Qur'an 69 So that he may warn him who is alive and feels, and justify the word against those who do not believe. 70 Do they not see Our handiwork: We created for them cattle which they own? 71 And We have subdued them unto them so that some of them they have for riding and some they eat. 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 But they have taken besides Allah [false] deities that perhaps they would be helped. 74 (But) they shall not be able to assist them, and they shall be a host brought up before them. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 76 Has the human being not considered that We have created him from a drop of fluid. He is openly quarrelsome. 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 78 Say thou: He shall quicken them Who brought them forth for the first time, and He is of every kind of creation the Knower! 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is He who created the heavens and earth not able to create others like these people? Of course He is! He is indeed the Supreme Creator, the All Knowing: 81 His Being alone is such that when He wills a thing to be, He but says unto 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
