It is God who provides livestock for you, some for riding and some for your food: 79 and find [yet other] benefits in them; and that through them you may attain to the fulfillment of [many] a heartfelt need: for on them, as on ships, you are borne [through life]. 80 And He shows you (always) His Signs: then which of the Signs of Allah will ye deny? 81 Have they never journeyed through the land and seen what was the end of those who have gone before them? They were stronger than themselves in might and left firmer traces upon the earth; yet, whatsoever they earned did not help them. 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 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 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
