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 have not taught him (Prophet Mohammed- peace and blessings be upon him) to recite poetry, nor does it befit him; it is nothing but an advice and the bright 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 Have they not seen how We have created for them the cattle they master with Our Hands? 71 And We have subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 Benefits and (divers) drinks have they from them. Will they not then give thanks? 73 And they have taken (other) gods beside Allah, in order that they may be helped. 74 Those deities can render them no help. Yet these devotees act as though they were an army in waiting for them. 75 So let not their speech grieve thee (O Muhammad). Lo! We know what they conceal and what proclaim. 76 Beholdest not man that We have created him from a sperm? Yet lo! he is a manifest disputer? 77 And he presents for Us an example and forgets his [own] creation. He says, "Who will give life to bones while they are disintegrated?" 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 "The same Who produces for you fire out of the green tree, when behold! ye kindle therewith (your own fires)! 80 How can He who created the heavens and the earth not be able to create others like them? Why not? He is the real creator 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 So glory be to Him who has control over all things. It is to Him that you will all be brought back. 83
