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 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, 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 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 Then, if they turn away, your duty (O Muhammad SAW) is only to convey (the Message) in a clear way. 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
