It is God who provides livestock for you, some for riding and some for your food: 79 you have other benefits in them too. You can reach any destination you wish on them: they carry you by land, as ships carry you on the sea. 80 And He showeth you His tokens. Which, then, of the tokens of Allah do ye deny? 81 What, have they not journeyed in the land and beheld how was the end of those before them? They were stronger than themselves in might and left firmer traces in the earth; yet that they earned did not avail them. 82 When their Messengers brought them clear verses they rejoiced in such knowledge as they had; but they were encompassed by that which they mocked. 83 Then when they behold Our prowess, they said: we believe in Allah alone, and we disbelieve in that which with Him we have been associating. 84 But their faith could not avail them when they saw Our doom. This is Allah's law which hath ever taken course for His bondmen. And then the disbelievers will be ruined. 85
