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 any poetry nor would it be fitting for him. This is merely a Reminder and a clear Quran 69 by which he may warn those who are living and may let the words of God come true against the unbelievers. 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 And We have tamed them for them, so some of them they ride, and some of them they eat. 72 And for them therein are [other] benefits and drinks, so will they not 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 have not the power to help them: but they will be brought up (before Our Judgment-seat) as a troop (to be condemned). 75 So let not their speech grieve thee (O Muhammad). Lo! We know what they conceal and what proclaim. 76 Doth not man see that it is We Who created him from sperm? yet behold! he (stands forth) as an open adversary! 77 And he strikes out a likeness for Us and forgets his own creation. Says he: Who will give life to the bones when they are rotten? 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again. He has the best knowledge of all creatures. 79 He Who created from a green tree a fire for you, a fire to light your stoves with.” 80 Is He who created the heavens and the earth unable to create their like? Yes, indeed, He is the Creator, the Knower. 81 His command is only when He intends a thing that He says to it, "Be," and it is. 82 Therefore Purity is to Him in Whose Hand* is the control over all things and it is towards Him that you will be returned. (Used as a metaphor to mean Power). 83
