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 has brought you forth from your mothers' wombs when you knew nothing, and then gave you hearing, and sight and thinking hearts so that you may 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 God has made your houses places of rest for you and made tents for you out of cattle hides, which are light for you to carry, both when you are travelling and when you are staying in one place. He provides for you from the wool and fur and hair of cattle, household goods and articles for use for a time. 80 And Allah has made for you out of that which He has created shades, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat (and cold), and coats of mail to protect you from your (mutual) violence. Thus does He perfect His Grace unto you, that you may submit yourselves to His Will (in Islam). 81 But if they turn away, thy duty is only to preach the clear Message. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
