And to Allah belongs the unseen [aspects] of the heavens and the earth. And the command for the Hour is not but as a glance of the eye or even nearer. Indeed, Allah is over all things competent. 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 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 Allah hath appointed for you from your houses a repose, and He hath appointed for you from the skins of the cattle houses which ye find light, on the day of your flitting and on the day of your stopping, and from their wools and their furs and their hair a furnishing and an enjoyment for a season. 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 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (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
