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 that he may warn whosoever is living, and that the Word may be realized against the unbelievers. 70 Have they not seen how We have created for them the cattle they master with Our Hands? 71 And We have subjected them to them, so some of them they have to ride upon, and some of them they eat. 72 And they have (other) profits from them (besides), and they get (milk) to drink. Will they not then be grateful? 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 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 that We created him from a drop. Yet there he is, flagrantly contentious, 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 revive them Who produced them at the first, for He is Knower of every 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 the earth Able to create the like of them? Aye, that He is! for He is the All-Wise Creator, 81 His command, when He intends anything, is only to say to it: Be, so it is. 82 So exalted is He in whose hand is the realm of all things, and to Him you will be returned. 83
