To Allah belongeth the Mystery of the heavens and the earth. And the Decision of the Hour (of Judgment) is as the twingkling of an eye, or even quicker: for Allah hath power over all things. 77 Allah has brought you forth from your mothers' wombs when you knew nothing, and then gave you hearing, and sight and thinking hearts so that you may give thanks. 78 Have you not considered the free movements of the birds high in the sky above? What keeps them aloft except God? In this there is evidence (of the truth) for the believing people. 79 Allah has made your houses a repose, and has provided you with the skins of the cattle for your habitation which are light to handle both when you travel and when you camp; and out of their wool and their fur and their hair He has given you furnishings and goods for use over a period of time. 80 And it is God who has appointed for you coverings of the things He created, and He has appointed for you of the mountains refuges, and He has appointed for you shirts to protect you from the heat, and shirts to protect you from your own violence. Even so He perfects His blessing upon you, that haply you will surrender. 81 But if they turn away, thy duty is only to preach the clear Message. 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
