But [let them always remember that] if We lengthen a human being's days, We also cause him to decline in his powers [when he grows old]: will they not, then, use their reason? 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 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 the cattle among things We have fashioned by Our power, which they own, 71 We have subdued them to them, and some of them they ride, and some they eat; 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 are not able to help them, and they [themselves] are for them soldiers in attendance. 75 So let not their speech grieve thee (O Muhammad). Lo! We know what they conceal and what proclaim. 76 Does not man see We created him from a drop of semen? Even then he becomes an open contender, 77 And he puts forth for Us a parable, and forgets his own creation. He says: "Who will give life to these bones when they have rotted away and became dust?" 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 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 the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 And His only task when He intends a thing is to command it, “Be” – and it thereupon happens! 82 Limitless, then, in His glory is He in whose hand rests the mighty dominion over all things; and unto Him you all will be brought back! 83
