To God belongs all the secrets of the heavens and the earth. It only takes God a twinkling of an eye or even less to make it the Day of Judgment. God has power over all things. 77 And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks. 78 Behold they not the birds subjected in the firmament of the heaven? Naught supporteth them save Allah; verily therein are signs for people who believe. 79 And Allah has given you houses for staying, and made some houses from the hides of animals, which are easy for you on your day of travel and on the day of stopover – and from their wool, and fur, and hair, some household items and utilities for a while. 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 favors of Allah, then they disbelieve them; most of them are unbelievers. 83
