Which of the signs of Allah do you disbelieve 40:78-85
40:78 We sent other Messengers before you; of some, We have already told you, of others We have not told you. Yet it was not for any Messenger to bring a verse except by the permission of Allah. And when the command of Allah comes the matter will be justly decided; and the vain-doers will be lost.
40:82 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.
40:83 When their Messengers brought them clear verses they rejoiced in such knowledge as they had; but they were encompassed by that which they mocked.
40:85 But when they saw Our Might their belief did not benefit them! It is the way of Allah that has passed concerning His worshipers. There, the unbelievers shall be lost.
