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 did not teach him (Muhammad) poetry, nor was he supposed to be a poet. It is only the word (of God) and the illustrious Quran 69 that he may warn whosoever is living, and that the Word may be realized against the unbelievers. 70 Have they not seen how We have created for them of Our handiwork the cattle, so that 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 derive other advantages and drinks from them. Even then they do not offer thanks, 73 And they have appointed Gods other than Allah, that perhaps they may be helped! 74 they are unable to succour their devotees, even though to them they may [appear to] be hosts drawn up [for succour]. 75 Therefore let not their speech grieve you; surely We know what they do in secret and what they do openly. 76 Does not man see that We have created him from Nutfah (mixed male and female discharge semen drops). Yet behold! He (stands forth) as an open opponent. 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 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 giveth you out of the green tree fire, and lo! ye kindle therewith. 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 His Being alone is such that when He wills a thing to be, He but says unto it, "Be" — and it is. 82 So glory to Him in Whose hands is the dominion of all things: and to Him will ye be all brought back. 83
