Allah has full knowledge of the truths beyond the reach of perception both in the heavens and the earth; and the coming of the Hour will take no more than the twinkling of an eye; it may take even less. Indeed Allah has power over everything. 77 God produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may 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 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 God has given you of things created, shade, and places of shelter in the mountains, and clothes for protection against the heat, and coats (of mail) for defence during war. He thus bestows His favours on you so that you may be grateful to Him. 81 But if they turn away, thy duty is only to preach the clear Message. 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
