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 poetry; it is not seemly for him. It is only a Remembrance and a Clear Koran, 69 that he may warn him who is alive and establish an argument against those that deny the Truth. 70 See they not that it is We Who have created for them - among the things which Our hands have fashioned - cattle, which are under their dominion?- 71 We have subdued these to them, and some of them they ride and some of them they eat; 72 And therein they have advantages and drinks; will they not then be grateful? 73 And they have taken beside Allah gods, hoping that haply they may be succoured. 74 They are not able to help them, and they [themselves] are for them soldiers in attendance. 75 Muhammad, let not their words annoy you. We certainly know whatever they conceal or reveal. 76 Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary? 77 And he has struck for Us a parable, and forgotten his own creation. He asks: 'Who will quicken the bones after they have decayed' 78 Say, "He will give them life who produced them the first time; and He is, of all creation, Knowing." 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 like of them? Yea! and He is the Creator (of all), the Knower. 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 Therefor Glory be to Him in Whose hand is the dominion over all things! Unto Him ye will be brought back. 83
