And to Allah belongs the unseen [aspects] of the heavens and the earth. And the command for the Hour is not but as a glance of the eye or even nearer. Indeed, Allah is over all things competent. 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 God has provided shade for you out of what He has created and places of retreat out of mountains. He has given you garments to protect you from the heat and cover your private parts. This is how He perfects His bounties to you so that perhaps you would submit to His will. 81 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They [who turn away from it] are fully aware of God's blessings, but none the less they refuse to acknowledge them [as such,] since most of them are given to denying the truth. 83
