To Allah belongs the unseen of the heavens and the earth. The matter of the Final Hour shall be like the twinkling of an eye, or even less. Allah has power over all things. 77 Allah brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 78 Do they not see the birds, constrained in the middle of the sky? None withholds them but Allah; most surely there are signs in this for a people who believe. 79 And Allah has given you a place to abide in your houses, and He has given you tents of the skins of cattle which you find light to carry on the day of your march and on the day of your halting, and of their wool and their fur and their hair (He has given you) household stuff and a provision for a 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, [O Muhammad] - then only upon you is [responsibility for] clear notification. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
