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 And Allah hath brought you forth from the bellies of your mothers while ye know not aught, and He hath appointed for you hearing and sight and hearts that haply ye might give thanks. 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 has given you a place to abide in your houses, and He has given you tents of the skins of cattle which you find light to carry on the day of your march and on the day of your halting, and of their wool and their fur and their hair (He has given you) household stuff and a provision for a time. 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 only duty is to clearly deliver the message of the truth. 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
