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 (Muhammad) to versify, nor is it worthy of him. This is nothing but a reminder and illuminating discourse, 69 that he may warn the living, and so that Judgement may be passed against the unbelievers. 70 Did they not see that We have created animals for them from Our handiwork, so they are their owners? 71 And We have subjected them to them, so some of them they have to ride upon, and some of them they eat. 72 And they have therefrom other benefits and drinks. Will they not then give thanks? 73 Yet they have taken, apart from God, gods; haply they might be helped. 74 Instead, the disbelievers will be brought into the presence of God as the soldiers of the idols. 75 So let not their speech grieve thee (O Muhammad). Lo! We know what they conceal and what proclaim. 76 And did not man see that We have created him from a drop of semen? Yet he is an open quarreller! 77 And he propoundeth for us a similitude, and forgetteth his creation; he saith: who shall quicken the bones when they are decayed? 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 the earth unable to create their like? Yes, indeed, He is the Creator, the Knower. 81 His affair, when He intendeth a thing, is only that He saith unto it: be, and it becometh. 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
