To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 When God brought you out of your mothers wombs, you knew nothing. He gave you ears, eyes, and hearts so that perhaps you would give Him 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 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 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They are aware of the favours of Allah, and yet refuse to acknowledge them. Most of them are determined not to accept the Truth. 83
