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 God produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may be grateful. 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 From the things He created, Allah has given you a covering shade, and He has made for you refuges in the mountains. He has given you garments to protect you from the heat, and garments to protect you from your own violence. As such it is that He perfects His favors upon you, in order that you submit. 81 But if they turn away, [O Muhammad] - then only upon you is [responsibility for] clear notification. 82 They recognize the favor of Allah; then they deny it. And most of them are disbelievers. 83
