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 God produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may be grateful. 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 God has given you homes to live in, and tents (made) from the hides of cattle convenient for days of travelling and halting; and from their wool and fur and hair you make domestic articles and goods that last a certain time. 80 And Allah has made for you of what He has created shelters, and He has given you in the mountains places of retreat, and He has given you garments to preserve you from the heat and coats of mail to preserve you in your fighting; even thus does He complete His favor upon you, that haply you may submit. 81 BUT IF they turn away [from thee, O Prophet, remember that] thy only duty is a clear delivery of the message [entrusted to thee]. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
