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 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 never noticed the birds how they are held under control in the middle of the sky, where none holds them (from falling) except Allah? Surely 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 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 If they still turn away, your duty is to warn them in clear terms. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
