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 did not give Prophet Muhammad, knowledge of poetry, nor is it befitting for him. It is not but a message and a clear Qur'an 69 by which he may warn those who are living and may let the words of God come true against the unbelievers. 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 And We have tamed them for them, so some of them they ride, and some of them they eat. 72 And they have therefrom other benefits and drinks. Will they not then give thanks? 73 And they have taken besides Allah aliha (gods), hoping that they might be helped (by those so called gods). 74 They cannot help them, though they be hosts made ready for them. 75 However, be not grieved by the sayings of those [who deny the truth]: verily, We know all that they keep secret as well as all that they bring into the open. 76 Does not man see that We have created him from the small seed? Then lo! he is an open disputant. 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 Say: He will revive them Who produced them at the first, for He is Knower of every creation, 79 He Who created from a green tree a fire for you, a fire to light your stoves with.” 80 How can He who created the heavens and the earth not be able to create others like them? Why not? He is the real creator all-knowing. 81 When He wills a thing He has only to say: "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
