God alone has knowledge of the hidden reality of the heavens and the earth; and the coming of the Hour [of Judgement] is like the twinkling of an eye, or even quicker. Surely God has full 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 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 God has given you [the ability to build] your houses as places of rest, and has endowed you with [the skill to make] dwellings out of the skins of animals - easy for you to handle when you travel and when you camp - and [to make] furnishings and goods for temporary use of their [rough] wool and their soft furry wool and their hair. 80 And Allah hath appointed for you, of that which He hath created shades, and He hath appointed for you from the mountains places of retreat, and He hath appointed for you coats protecting you from the heat and coats protecting you from the violence. Thus He perfecteth His favour on you that haply ye may submit. 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 are aware of the favours of Allah, and yet refuse to acknowledge them. Most of them are determined not to accept the Truth. 83
