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 it may give admonition to any (who are) alive, and that the charge may be proved against those who reject (Truth). 70 Have they not seen how We have created for them of Our handiwork the cattle, so that they are their owners, 71 We have subjected these to them, so that some may be used for riding and some for food, 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 They have set up other gods besides God, hoping to be helped by them, 74 Those deities can render them no help. Yet these devotees act as though they were an army in waiting for them. 75 Let not their speech, then, grieve thee. Verily We know what they hide as well as what they disclose. 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 He questions Our Resurrection of him, but has forgotten his own creation. He has said, "Who will give life to the bones which have become ashes?" 78 Say: He will revive them Who produced them at the first, for He is Knower of every creation, 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is He who created the heavens and earth not able to create others like these people? Of course He is! He is indeed the Supreme Creator, the All Knowing: 81 His command, when He desires a thing, 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
