Allah it is Who has made cattle for you so that you ride some of them and from some of them you derive food. 79 And there are advantages for you in them, and that you may attain thereon a want which is in your breasts, and upon them and upon the ships you are borne. 80 And He shows you His signs: which then of Allah's signs will you deny? 81 Did they not journey in the land that they may behold the end of those who had gone before them? They were more numerous and greater in strength and left behind more splendid traces in the land. Yet their attainments did not avail them. 82 Then when their Messengers came to them with clear proofs, they were glad (and proud) with that which they had of the knowledge (of worldly things): And that at which they used to mock, surrounded them (i.e. the punishment). 83 Then, when they saw Our might, they said, 'We believe in God alone, and we disbelieve in that we were associating 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
