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 Allah brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 78 Behold they not the birds subjected in the firmament of the heaven? Naught supporteth them save Allah; verily therein are signs for people 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 It is Allah Who made out of the things He created, some things to give you shade; of the hills He made some for your shelter; He made you garments to protect you from heat, and coats of mail to protect you from your (mutual) violence. Thus does He complete His favours on you, that ye may bow to His Will (in Islam). 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
