If We extend anyone's life, We reverse his development. Can they not 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 That it may warn him who would have life, and (that) the word may prove true against the unbelievers. 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 We have subjected them to them, so some of them they have to ride upon, and some of them they eat. 72 other uses also they have in them, and beverages. What, will they not be thankful? 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 74 They will not be able to help them and will be brought (to Us) as their levied troops. 75 So do not let their saying grieve thee; assuredly We know what they keep secret and what they publish. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 77 And he makes comparisons for Us, and forgets his own (origin and) Creation: He says, "Who can give life to (dry) bones and decomposed ones (at that)?" 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 He who produces for you fire out of the green tree, so that, lo! you kindle [your fires] therewith." 80 Is not He who created the heavens and the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 All glory belongs to the One in whose hands is the control of all things. To Him you will all return. 83
