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 have not taught (Muhammad) to versify, nor is it worthy of him. This is nothing but a reminder and illuminating discourse, 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 subjected them to them, so some of them they have to ride upon, and some of them they eat. 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 taken gods besides Allah that they may be helped. 74 It is not in their power to help them; but they (the worshippers) are unto them a host in arms. 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 man not see that We created him of a sperm drop, and lo! he is flagrantly contentious? 77 And he has struck for Us a parable, and forgotten his own creation. He asks: 'Who will quicken the bones after they have decayed' 78 Say: "He who brought them into being in the first instance will give them life [once again,] seeing that He has full knowledge of every act of creation: 79 He has created fire for you out of the green tree from which you can kindle other fires. 80 And is it not possible for the One Who created the heavens and the earth to create the likes of them? It is surely possible, why not? And He is the Great Creator, the All Knowing of everything. 81 Whenever He wills a thing, He just commands it “Be” and it is. 82 Holy is He Who has full control over everything, and to Him you shall all be recalled. 83
