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 produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may be grateful. 78 Have, then, they [who deny the truth] never considered the birds, enabled [by God] to fly in mid-air, with none but God holding them aloft? In this, behold, there are messages indeed for people who will believe! 79 And Allah has given you houses for staying, and made some houses from the hides of animals, which are easy for you on your day of travel and on the day of stopover – and from their wool, and fur, and hair, some household items and utilities for a while. 80 God has granted you shade out of what He has created, places of shelter in the mountains, garments with which to protect yourselves from the heat and coats of mail to shield you in battle. Thus He completes His favour to you, so that you may submit wholly to Him. 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
