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 So that he may warn him who is alive and feels, and justify the word against those who do not believe. 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 that We have subjected them to their (use)? of them some do carry them and some they eat: 72 And therein they have advantages and drinks; will they not then be grateful? 73 And they have taken (other) gods beside Allah, in order that they may be helped. 74 but they are not able to help them: rather they will be brought before God as their allied host. 75 So do not let their saying grieve thee; assuredly We know what they keep secret and what they publish. 76 Does man not consider that We created him from a [mere] sperm-drop - then at once he is a clear adversary? 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again. He has the best knowledge of all creatures. 79 Who giveth you out of the green tree fire, and lo! ye kindle therewith. 80 "Is not He Who created the heavens and the earth able to create the like thereof?" - Yea, indeed! for He is the Creator Supreme, of skill and knowledge (infinite)! 81 When He wills a thing, His command is to say to it 'Be', and it is! 82 So all glory to Him who holds all power over everything, to whom you will go back in the end. 83
