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 him (Prophet Muhammad) poetry, nor does it become him. This is only a Remembrance and a Clear Holy Reading (Koran) 69 that he may warn the living, and so that Judgement may be passed against the unbelievers. 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 Whom We made subservient to them so that some of them they ride and some they eat? 72 And therein they have advantages and drinks; will they not then be grateful? 73 And they have appointed Gods other than Allah, that perhaps they may be helped! 74 Those deities can render them no help. Yet these devotees act as though they were an army in waiting for them. 75 So let not their speech grieve thee. Verily We! We know whatsoever they keep secret and whatsoever they make known. 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 And he hath coined for Us a similitude, and hath forgotten the fact of his creation, saying: Who will revive these bones when they have rotted away? 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 Who has made for you the fire (to burn) from the green tree, so that with it you kindle (fire). 80 Is the One who has created the heavens and the earth not able to create another creature like the human being? He certainly has the power to do so. He is the Supreme Creator and is All-knowing. 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 Holy is He Who has full control over everything, and to Him you shall all be recalled. 83
