To Allah belongs the unseen of the heavens and the earth. The matter of the Final Hour shall be like the twinkling of an eye, or even less. Allah has power over all things. 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 they not regarded the birds, that are subjected in the air of heaven? Naught holds them but God; surely in that are signs for' a people who believe. 79 And Allah has made for you in your homes an abode, and made for you out of the hides of the cattle (tents for) dwelling, which you find so light (and handy) when you travel and when you stay (in your travels), and of their wool, fur, and hair (sheep wool, camel fur, and goat hair), a furnishing and articles of convenience (e.g. carpets, blankets, etc.), a comfort for a while. 80 And Allah hath given you, of that which He hath created, shelter from the sun; and hath given you places of refuge in the mountains, and hath given you coats to ward off the heat from you, and coats (of armour) to save you from your own foolhardiness. Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him). 81 If they still turn away, your duty is to warn them in clear terms. 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
