And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has power over all things. 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 Have they not regarded the birds, that are subjected in the air of heaven? Naught holds them but God; surely in that are signs for' a people 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 appointed for you, of that which He hath created shades, and He hath appointed for you from the mountains places of retreat, and He hath appointed for you coats protecting you from the heat and coats protecting you from the violence. Thus He perfecteth His favour on you that haply ye may submit. 81 Then, if they turn away, your duty (O Muhammad SAW) is only to convey (the Message) in a clear way. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
