Whoever reaches old age, We reverse in natural disposition. Do they not have sense (to see)? 68 And We have not taught him poetry, nor is it meet for him; it is nothing but a reminder and a plain Quran, 69 to warn all who are truly alive, and to justify the word [God's verdict] against the deniers. 70 See they not that it is We Who have created for them - among the things which Our hands have fashioned - cattle, which are under their dominion?- 71 We have subjected the cattle to them so that some of them they ride and eat the flesh of others. 72 They derive a variety of benefits and drinks from them. Will they, then, not give thanks? 73 But [nay,] they take to worshipping deities other than God, [hoping] to be succoured [by them, and not knowing that] 74 Instead, the disbelievers will be brought into the presence of God as the soldiers of the idols. 75 So be not grieved by what they say. We certainly know what they hide and disclose. 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 parable, and forgotten his own creation. He asks: 'Who will quicken the bones after they have decayed' 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again.

Why not? He is the real creator all-knowing. 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
