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 by which he may warn those who are living and may let the words of God come true against the unbelievers. 70 Do they not see that We have created for them from what Our hands have made, grazing livestock, and [then] they are their owners? 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 also have other uses in them and drinks. What, will they not give thanks! 73 And they have taken (other) gods beside Allah, in order that they may be helped. 74 They are not able to give them succour; whereas they shall be against them host brought forward. 75 However, be not grieved by the sayings of those [who deny the truth]: verily, We know all that they keep secret as well as all that they bring into the open. 76 Does not man see We created him from a drop of semen? Even then he becomes an open contender, 77 And he strikes out a likeness for Us and forgets his own creation. Says he: Who will give life to the bones when they are rotten? 78 Say: “He Who first brought them into being will quicken them; He knows well about every kind of creation; 79 Who giveth you out of the green tree fire, and lo! ye 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 command is only when He intends a thing that He says 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
