And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has power over all things. 77 Allah brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 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 God has made your houses places of rest for you and made tents for you out of cattle hides, which are light for you to carry, both when you are travelling and when you are staying in one place. He provides for you from the wool and fur and hair of cattle, household goods and articles for use for a time. 80 God has provided shade for you out of what He has created and places of retreat out of mountains. He has given you garments to protect you from the heat and cover your private parts. This is how He perfects His bounties to you so that perhaps you would submit to His will. 81 But, if they turn away, your mission is only to give plain warning. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
