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 brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks. 78 Have they not seen the birds, subservient in the open skies? No one holds them up except Allah; indeed in this are signs for the 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 Allah has made for you of what He has created shelters, and He has given you in the mountains places of retreat, and He has given you garments to preserve you from the heat and coats of mail to preserve you in your fighting; even thus does He complete His favor upon you, that haply you may submit. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
