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 it may warn him who would have life, and (that) the word may prove true against the unbelievers. 70 Do they not see that, among the things which Our hands have fashioned, We have created for them cattle of which they are the masters, 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 (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 Yet they take (for worship) gods other than Allah, (hoping) that they might be helped! 74 It is not in their power to help them; but they (the worshippers) are unto them a host in arms. 75 Let not their words grieve you. Surely We know all things about them, what they conceal and what they reveal. 76 Does not man see that We created him from a drop. Yet there he is, flagrantly contentious, 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, "He who brought them into being in the first instance will give them life again: He has knowledge of every type of creation: 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 these? Yea! He is the Supreme Creator, the Knower. 81 His command, when He desires a thing, is to say to it 'Be,' and it is. 82 So glory be to Him, in whose hand is the dominion of everything, and unto whom you shall be returned. 83
