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 have not taught him (Prophet Mohammed- peace and blessings be upon him) to recite poetry, nor does it befit him; it is nothing but an advice and the bright Qur’an. 69 To warn the living*, and to prove the Word against disbelievers. (Only the believers are deemed alive in Allah’s sight.) 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 And We have subdued them unto them so that some of them they have for riding and some they eat. 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 But they have taken besides Allah [false] deities that perhaps they would be helped. 74 It is not in their power to help them; but they (the worshippers) are unto them a host in arms. 75 Let not their words grieve you. We have knowledge of all that they conceal and all that they reveal. 76 Has the human not seen how We created him from a drop (of sperm)? Yet he is a clear opponent. 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 thou: He shall quicken them Who brought them forth for the first time, and He is of every kind of creation the Knower! 79 He has created fire for you out of the green tree from which you can kindle other fires. 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 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
