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 to the end that it may warn everyone who is alive [of heart,] and that the word [of God] may bear witness against all who deny the truth. 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 for them therein are [other] benefits and drinks, so will they not be grateful? 73 They have set up other gods besides God, hoping to be helped by them, 74 They cannot help them, for them (the so called) army are brought (with them to Hell). 75 Therefore let not their speech grieve you; surely We know what they do in secret and what they do openly. 76 Has the human being not considered that We have created him from a drop of fluid. He is openly quarrelsome. 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 give life to them Who brought them into existence at first, and He is cognizant of all creation 79 Who gave you fire from a green tree, with which you ignite the flame." 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 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 All glory belongs to the One in whose hands is the control of all things. To Him you will all return. 83
