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 Did they not see that We have created animals for them from Our handiwork, so they are their owners? 71 And have subjected the animals for them, so they ride some animals and eat some? 72 And for them therein are [other] benefits and drinks, so will they not be grateful? 73 Yet they have taken, apart from God, gods; haply they might be helped. 74 they are unable to succour their devotees, even though to them they may [appear to] be hosts drawn up [for succour]. 75 Let not their words grieve you. Surely We know all things about them, what they conceal and what they reveal. 76 Hath not man seen that We have created him from a drop of seed? Yet lo! he is an open opponent. 77 And applies comparisons to Us, having forgotten his origin, and says: "Who can put life into decayed bones?" 78 Say, "He will give them life Who created them for the first time! for He is Well-versed in every kind of creation!- 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is not He Who created the heavens and the earth Able to create the like of them? Aye, that He is! for He is the All-Wise Creator, 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 Therefore Purity is to Him in Whose Hand* is the control over all things and it is towards Him that you will be returned. (Used as a metaphor to mean Power). 83
