If We extend anyone's life, We reverse his development. Can they not use their reason? 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 to the end that it may warn everyone who is alive [of heart,] and that the word [of God] may bear witness against all who deny the truth. 70 Do they not see that We have created for them from what Our hands have made, grazing livestock, and [then] they are their owners? 71 We have subjected these to them, so that some may be used for riding and some for food, 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 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 So do not let their saying grieve thee; assuredly We know what they keep secret and what they publish. 76 Has the human not seen how We created him from a drop (of sperm)? Yet he is a clear opponent. 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 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 has created fire for you out of the green tree from which you can kindle other fires. 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 His command is only when He intends a thing that He says to it, "Be," and it is. 82 So glory be to Him who has control over all things. It is to Him that you will all be brought back. 83
