To Allah belongs the unseen of the heavens and the earth. The matter of the Final Hour shall be like the twinkling of an eye, or even less. Allah has 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 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 has made for you out of that which He has created shades, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat (and cold), and coats of mail to protect you from your (mutual) violence. Thus does He perfect His Grace unto you, that you may submit yourselves to His Will (in Islam). 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
