It is God who appointed for you the cattle, some of them to ride and of some you eat; 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 shows you His signs; so which sign of Allah will you deny? 81 Have they not travelled through the earth and seen what was the end of those before them? They were more numerous than them and mightier in strength, and in the traces (they have left behind them) in the land, yet all that they used to earn availed them not. 82 And when their messengers brought them clear proofs (of Allah's Sovereignty) they exulted in the knowledge they (themselves) possessed. And that which they were wont to mock befell them. 83 Then, when they saw Our doom, they said: We believe in Allah only and reject (all) that we used to associate (with Him). 84 But their belief when they saw Our might did not profit them -- the wont of God, as in the past, touching His servants; then the unbelievers shall be lost. 85
