To God belongs all the secrets of the heavens and the earth. It only takes God a twinkling of an eye or even less to make it the Day of Judgment. God has power over all things. 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 Do they not look at the birds, held poised in the midst of (the air and) the sky? Nothing holds them up but (the power of) Allah. Verily in this are signs for those 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 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 Then if they turn away, O dear Prophet, (Mohammed – peace and blessings be upon him) upon you is nothing but to clearly convey (the message). 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
