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 And We did not give Prophet Muhammad, knowledge of poetry, nor is it befitting for him. It is not but a message and a clear Qur'an 69 to warn all who are truly alive, and to justify the word [God's verdict] against the deniers. 70 Have they not seen how We have created for them the cattle they master with Our Hands? 71 We have subjected the cattle to them so that some of them they ride and eat the flesh of others. 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 And they have taken (other) gods beside Allah, in order that they may be helped. 74 They (the appointed Gods) cannot help them; and they and their armies will come (to Us), as captives. 75 So let not their speech grieve you. Indeed, We know what they conceal and what they declare. 76 And did not man see that We have created him from a drop of semen? Yet he is an open quarreller! 77 And he presents for Us an example and forgets his [own] creation. He says, "Who will give life to bones while they are disintegrated?" 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 [It is] He who made for you from the green tree, fire, and then from it you ignite. 80 Is not He, who created the heavens and earth, able to create the like of them? Yes indeed; He is the All-creator, the All-knowing. 81 when He decrees a thing, He need only say, "Be!" and it is. 82 Therefor Glory be to Him in Whose hand is the dominion over all things! Unto Him ye will be brought back. 83
