۞ And remember the brother of Ad, when he warned his people beside the sand-dunes -- and already warners had passed away alike before him and behind him -- saying, 'Serve none but God! Truly I fear for you the chastisement of a dreadful day. 21 They said, "Have you come to delude us away from our gods? Then bring us what you promise us, if you should be of the truthful." 22 He replied: “Allah alone knows about this. I only convey to you the Message that I have been sent with. But I see that you are an ignorant people.” 23 So when they saw it as a cloud advancing towards their valleys, they said: "This is just a passing cloud that will bring us rain." "No. It is what you were trying to hasten: The wind which carries the grievous punishment! 24 Destroying all things by commandment of its Lord. And morning found them so that naught could be seen save their dwellings. Thus do We reward the guilty folk. 25 We had established them more firmly in the land than you are. We had given them ears, eyes, and hearts but none of their ears, eyes, and hearts proved to be of any benefit to them; they rejected the revelations of God and the torment which they mocked brought upon them utter destruction. 26
