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 they never noticed the birds how they are held under control in the middle of the sky, where none holds them (from falling) except Allah? Surely there are signs in this for those who believe. 79 And Allah has made for you from your homes a place of rest and made for you from the hides of the animals tents which you find light on your day of travel and your day of encampment; and from their wool, fur and hair is furnishing and enjoyment for a time. 80 And Allah has made for you of what He has created shelters, and He has given you in the mountains places of retreat, and He has given you garments to preserve you from the heat and coats of mail to preserve you in your fighting; even thus does He complete His favor upon you, that haply you may submit. 81 Then if they turn away, on thee is only the preaching plain. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
