And God's [alone] is the knowledge of the hidden reality of the heavens and the earth. And so, the advent of the Last Hour will but manifest itself [in a single moment,] like the twinkling of an eye, or closer still: for, behold, God has the power to will anything. 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 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 It is Allah Who made out of the things He created, some things to give you shade; of the hills He made some for your shelter; He made you garments to protect you from heat, and coats of mail to protect you from your (mutual) violence. Thus does He complete His favours on you, that ye may bow to His Will (in Islam). 81 Then if they turn away, on thee is only the preaching plain. 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
