And God's [alone] is the knowledge of the hidden reality of the heavens and the earth. And so, the advent of the Last Hour will but manifest itself [in a single moment,] like the twinkling of an eye, or closer still: for, behold, God has the power to will anything. 77 God brought you forth from the wombs of your mothers while you knew nothing, and gave you hearing and sight and hearts, so that you might be grateful. 78 Do you not see the birds held high between the heavens and the earth? Nothing holds them (aloft) but God. There are verily signs in this for those 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 it is God who has appointed for you coverings of the things He created, and He has appointed for you of the mountains refuges, and He has appointed for you shirts to protect you from the heat, and shirts to protect you from your own violence. Even so He perfects His blessing upon you, that haply you will surrender. 81 But, if they turn away, your mission is only to give plain warning. 82 They are aware of the favours of Allah, and yet refuse to acknowledge them. Most of them are determined not to accept the Truth. 83
