To Allah belongeth the Mystery of the heavens and the earth. And the Decision of the Hour (of Judgment) is as the twingkling of an eye, or even quicker: for Allah hath power over all things. 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 Have they not regarded the birds, that are subjected in the air of heaven? Naught holds them but God; surely in that are signs for' a people who believe. 79 Allah has made your houses a repose, and has provided you with the skins of the cattle for your habitation which are light to handle both when you travel and when you camp; and out of their wool and their fur and their hair He has given you furnishings and goods for use over a period of time. 80 And Allah has made for you, from that which He has created, shadows and has made for you from the mountains, shelters and has made for you garments which protect you from the heat and garments which protect you from your [enemy in] battle. Thus does He complete His favor upon you that you might submit [to Him]. 81 But, if they turn away, your mission is only to give plain warning. 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
