To God belongs the Unseen in the heavens and in the earth. And the matter of the Hour is as a twinkling of the eye, or nearer. Surely God is powerful over everything. 77 Allah has brought you forth from your mothers' wombs when you knew nothing, and then gave you hearing, and sight and thinking hearts so that you may give thanks. 78 Have they not seen the birds that are subjected in the air of the heaven? Nothing holds them except Allah. Surely, in this are signs for those 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 If they still turn away, your duty is to warn them in clear terms. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
