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 And God has brought you forth from your mothers' wombs knowing nothing - but He has endowed you with hearing, and sight, and minds, so that you might have cause to be grateful. 78 Have, then, they [who deny the truth] never considered the birds, enabled [by God] to fly in mid-air, with none but God holding them aloft? In this, behold, there are messages indeed for people who will believe! 79 And it is Allah who has given you houses in which to rest, and from the hides of cattle homes so they are light for you on the day you travel and on the day of settling; while from their wool, fur, and hair (He has given you) furnishing and enjoyment 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, you are responsible only for conveying the message clearly. 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
