Whoever reaches old age, We reverse in natural disposition. Do they not have sense (to see)? 68 We did not teach him (Muhammad) poetry, nor was he supposed to be a poet. It is only the word (of God) and the illustrious Quran 69 That it may warn him who would have life, and (that) the word may prove true against the unbelievers. 70 Do they not see that, among the things which Our hands have fashioned, We have created for them cattle of which they are the masters, 71 We have subjected these to them, so that some may be used for riding and some for food, 72 Benefits and (divers) drinks have they from them. Will they not then give thanks? 73 But they have taken besides Allah [false] deities that perhaps they would be helped. 74 They will not be able to help them and will be brought (to Us) as their levied troops. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 76 Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary? 77 And he invents an example for Us, while forgetting his own creation, saying, “Who is such that can revive the bones when they have completely rotted away?” 78 Say, "He will give them life who produced them the first time; and He is, of all creation, Knowing." 79 Who hath appointed for you fire from the green tree, and behold! ye kindle from it. 80 Is not He, who created the heavens and earth, able to create the like of them? Yes indeed; He is the All-creator, the All-knowing. 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 So glory be to Him who has control over all things. It is to Him that you will all be brought back. 83
