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 has provided you shade with the things He has created, and created for you refuge in the hills, and created some clothing for you to protect you from the heat, and some clothing to protect you during conflict; this is how He completes His favour upon you, so that you may obey. 81 But if they turn away, [O Muhammad] - then only upon you is [responsibility for] clear notification. 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
