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 him (Prophet Muhammad) poetry, nor does it become him. This is only a Remembrance and a Clear Holy Reading (Koran) 69 that he may warn him who is alive and establish an argument against those that deny the Truth. 70 Do they not see that We have created cattle for them, out of what Our hands have wrought, so they are their masters? 71 We have subjected these to them, so that some may be used for riding and some for food, 72 From cattle they get milk and other benefits. Will they not then give thanks? 73 And take other gods apart from God that they may perhaps give them help. 74 They cannot help them, though they be hosts made ready for them. 75 So do not let their sayings grieve you. Surely, We have knowledge of what they hide and all that they reveal. 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 hath coined for Us a similitude, and hath forgotten the fact of his creation, saying: Who will revive these bones when they have rotted away? 78 Say: 'He will quicken them who originated them the first time; He has knowledge of every creation; 79 Who gave you fire from a green tree, with which you ignite the flame." 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 command, when He intends anything, is only to say to it: Be, so it is. 82 Exaltations to Him in whose Hand is the Kingdom of all things, and to Him you will be returned. 83
