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 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 you not considered the free movements of the birds high in the sky above? What keeps them aloft except God? In this there is evidence (of the truth) for the believing people. 79 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 80 And among the many objects of His creation, God has appointed for you [various] means of protection: thus, He has given you in the mountains places of shelter, and has endowed you with [the ability to make] garments to protect you from heat [and cold,] as well as such garments as might protect you from your [mutual] violence. In this way does He bestow the full measure of His blessings on you, so that you might surrender yourselves unto Him. 81 But if they turn away, [O Muhammad] - then only upon you is [responsibility for] clear notification. 82 They recognise the Grace of Allah, yet they deny it (by worshipping others besides Allah) and most of them are disbelievers (deny the Prophethood of Muhammad SAW). 83
