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 not regarded the birds, that are subjected in the air of heaven? Naught holds them but God; surely in that are signs for' a people who believe. 79 And God has given you [the ability to build] your houses as places of rest, and has endowed you with [the skill to make] dwellings out of the skins of animals - easy for you to handle when you travel and when you camp - and [to make] furnishings and goods for temporary use of their [rough] wool and their soft furry wool and their hair. 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, your mission is only to give plain warning. 82 They recognize the blessing of God, then they deny it, and the most of them are the unthankful. 83
