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 that he may warn him who is alive and establish an argument against those that deny the Truth. 70 Observe they not that We have created for them, of that which Our hands have worked, cattle: so that they are their owners. 71 We have subdued them to them, and some of them they ride, and some they eat; 72 From cattle they get milk and other benefits. Will they not then give thanks? 73 They chose idols besides God in the hope of receiving help from them, but they will not be able to help them. 74 They will not be able to help them and will be brought (to Us) as their levied troops. 75 Let not their words grieve you. Surely We know all things about them, what they conceal and what they reveal. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 77 And he has struck for Us a similitude and forgotten his creation; he says, 'Who shall quicken the bones when they are decayed?' 78 Say: (O Muhammad SAW) "He will give life to them Who created them for the first time! And He is the All-Knower of every creation!" 79 He Who created from a green tree a fire for you, a fire to light your stoves with.” 80 Is not He who created the heavens and the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 And His only task when He intends a thing is to command it, “Be” – and it thereupon happens! 82 Exaltations to Him in whose Hand is the Kingdom of all things, and to Him you will be returned. 83
