God alone has knowledge of the hidden reality of the heavens and the earth; and the coming of the Hour [of Judgement] is like the twinkling of an eye, or even quicker. Surely God has full power over everything. 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 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 God has provided shade for you out of what He has created and places of retreat out of mountains. He has given you garments to protect you from the heat and cover your private parts. This is how He perfects His bounties to you so that perhaps you would submit to His will. 81 But, if they turn away, your mission is only to give plain warning. 82 They recognize the favor of Allah, yet they deny it, and most of them are ungrateful. 83
