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 have not taught him (Muhammad) poetry, nor is it meet for him. This is naught else than a Reminder and a Lecture making plain, 69 To warn whoever is alive and justify the word against the disbelievers. 70 Do they not see that We have created for them from what Our hands have made, grazing livestock, and [then] 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 they also have other uses in them and drinks. What, will they not give thanks! 73 But they have taken besides Allah [false] deities that perhaps they would be helped. 74 They cannot help them, though they be hosts made ready for them. 75 Therefore (O dear Prophet Mohammed – peace and blessings be upon him) do not grieve because of what they (the disbelievers) say; indeed We know what they conceal and what they disclose. 76 Beholdest not man that We have created him from a sperm? Yet lo! he is a manifest disputer? 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 thou: He shall quicken them Who brought them forth for the first time, and He is of every kind of creation the Knower! 79 He, Who produces for you fire out of the green tree, when behold! You kindle therewith. 80 Is He who created the heavens and earth not able to create others like these people? Of course He is! He is indeed the Supreme Creator, the All Knowing: 81 Verily, when He intends a thing, His Command is, "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
