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 There are advantages for you in them, so that you may satisfy your needs through them, and may be borne upon them and on ships. 80 And He shows you His signs; so which sign of Allah will you deny? 81 Have they not travelled in the earth so that they may behold what wise hath been the end of those before them. They were more numerous than these, and mightier in strength and the traces in the land. But naught availed them of that which they had been earning. 82 And when their apostles came unto them with evidences, they exulted in the knowledge which was with them, and there surrounded them that which they had been mocking. 83 And when they saw Our punishment, they said," We believe in Allah alone and disbelieve in that which 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
