To Allah belongeth the Mystery of the heavens and the earth. And the Decision of the Hour (of Judgment) is as the twingkling of an eye, or even quicker: for Allah hath power over all things. 77 And Allah has brought you forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts that you may give thanks. 78 Do they not see the birds held poised in the vault of heaven? Nothing holds them up except God. Truly, there are signs in this for those who believe. 79 And Allah hath given you in your houses an abode, and hath given you (also), of the hides of cattle, houses which ye find light (to carry) on the day of migration and on the day of pitching camp; and of their wool and their fur and their hair, caparison and comfort for a while. 80 And Allah hath given you, of that which He hath created, shelter from the sun; and hath given you places of refuge in the mountains, and hath given you coats to ward off the heat from you, and coats (of armour) to save you from your own foolhardiness. Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him). 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They [who turn away from it] are fully aware of God's blessings, but none the less they refuse to acknowledge them [as such,] since most of them are given to denying the truth. 83
