Whoever reaches old age, We reverse in natural disposition. Do they not have sense (to see)? 68 We have not instructed the (Prophet) in Poetry, nor is it meet for him: this is no less than a Message and a Qur'an making things clear: 69 That he or it (Muhammad SAW or the Quran) may give warning to him who is living (a healthy minded the believer), and that Word (charge) may be justified against the disbelievers (dead, as they reject the warnings). 70 Do they not see that We have created for them of what Our Hands have created, the cattle, so that they are their owners. 71 We have subdued these to them, and some of them they ride and some of them they eat; 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then 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 Therefore (O dear Prophet Mohammed – peace and blessings be upon him) do not grieve because of what they (the disbelievers) say; indeed We know what they conceal and what they disclose. 76 Has the human not seen how We created him from a drop (of sperm)? Yet he is a clear opponent. 77 And he has struck for Us a similitude and forgotten his creation; he says, 'Who shall quicken the bones when they are decayed?' 78 Say: "He who created you the first time. He has knowledge of every creation, 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 the earth able to create the like of them? Yea! and He is the Creator (of all), the Knower. 81 When He wills a thing, His command is to say to it 'Be', and it is! 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
