And to Allah belongs the unseen of the heavens and the earth. And the matter of the Hour is not but as a twinkling of the eye, or even nearer. Truly! Allah is Able to do all things. 77 And it is God who brought you forth from your mothers' wombs, and He appointed for you hearing, and sight, and hearts, that haply so you will be thankful. 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 out of that which He has created shades, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat (and cold), and coats of mail to protect you from your (mutual) violence. Thus does He perfect His Grace unto you, that you may submit yourselves to His Will (in Islam). 81 But if they turn away, you are responsible only for conveying the message clearly. 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
