To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks. 78 Do they not see the birds held poised in the vault of heaven? Nothing holds them up except God. Truly, there are signs in this 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 has provided you shade with the things He has created, and created for you refuge in the hills, and created some clothing for you to protect you from the heat, and some clothing to protect you during conflict; this is how He completes His favour upon you, so that you may obey. 81 BUT IF they turn away [from thee, O Prophet, remember that] thy only duty is a clear delivery of the message [entrusted to thee]. 82 They [who turn away from it] are fully aware of God's blessings, but none the less they refuse to acknowledge them [as such,] since most of them are given to denying the truth. 83
