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 It is He Who brought you forth from the wombs of your mothers when ye knew nothing; and He gave you hearing and sight and intelligence and affections: that ye may give thanks (to Allah). 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 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 From the things He created, Allah has given you a covering shade, and He has made for you refuges in the mountains. He has given you garments to protect you from the heat, and garments to protect you from your own violence. As such it is that He perfects His favors upon you, in order that you submit. 81 But, if they turn away, your mission is only to give plain warning. 82 They know the favour of Allah and then deny it. Most of them are ingrates. 83
