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 to the end that it may warn everyone who is alive [of heart,] and that the word [of God] may bear witness against all who deny the truth. 70 Do they not see the cattle among things We have fashioned by Our power, which they own, 71 We have made the cattle subservient to them so they ride and consume them. 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 And they have appointed Gods other than Allah, that perhaps they may be helped! 74 They are not able to help them, and they [themselves] are for them soldiers in attendance. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 76 Doth not man see that it is We Who created him from sperm? yet behold! he (stands forth) as an open adversary! 77 And he makes comparisons for Us, and forgets his own (origin and) Creation: He says, "Who can give life to (dry) bones and decomposed ones (at that)?" 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 He Who has made for you the fire (to burn) from the green tree, so that with it you kindle (fire). 80 Has He Who created the heavens and the earth no power to create the likes of them? Yes, indeed, He is the Superb Creator. 81 when He decrees a thing, He need only say, "Be!" and it is. 82 Wherefore hallowed be He in whose hand is the governance of everything, and unto whom ye shall be returned. 83
