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 Allah brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 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 And Allah hath given you in your houses an abode, and hath given you (also), of the hides of cattle, houses which ye find light (to carry) on the day of migration and on the day of pitching camp; and of their wool and their fur and their hair, caparison and comfort for a while. 80 And among the many objects of His creation, God has appointed for you [various] means of protection: thus, He has given you in the mountains places of shelter, and has endowed you with [the ability to make] garments to protect you from heat [and cold,] as well as such garments as might protect you from your [mutual] violence. In this way does He bestow the full measure of His blessings on you, so that you might surrender yourselves unto Him. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
