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 To warn whosoever liveth, and that the word may be fulfilled against the disbelievers. 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 subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 Yet they take (for worship) gods other than Allah, (hoping) that they might be helped! 74 They are not able to give them succour; whereas they shall be against them host brought forward. 75 Muhammad, let not their words annoy you. We certainly know whatever they conceal or reveal. 76 Has the human not seen how We created him from a drop (of sperm)? Yet he is a clear opponent. 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, "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 has made fire for you from the green tree with which you kindle' 80 Is not He who created the heavens and the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 When He wills a thing, His command is to say to it 'Be', and it is! 82 So glory be to Him who has control over all things. It is to Him that you will all be brought back. 83
