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 We have not taught (Muhammad) to versify, nor is it worthy of him. This is nothing but a reminder and illuminating discourse, 69 That he or it (Muhammad SAW or the Quran) may give warning to him who is living (a healthy minded the believer), and that Word (charge) may be justified against the disbelievers (dead, as they reject the warnings). 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 subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 And they derive other advantages and drinks from them. Even then they do not offer thanks, 73 They set up deities apart from Allah, hoping that they will receive help from them. 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 Hath not man seen that We have created him from a drop of seed? Yet lo! he is an open opponent. 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 will quicken them who originated them the first time; He has knowledge of every creation; 79 who has made for you out of the green tree fire and lo, from it you kindle.' 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 His affair, when He intendeth a thing, is only that He saith unto it: be, and it becometh. 82 So glory to Him in Whose hands is the dominion of all things: and to Him will ye be all brought back. 83
