۞ 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 us in order to turn us away from our Gods? Therefore bring upon us what you promise us, if you are truthful.” 22 He said, "God alone knows when it will come, and I deliver to you the message with which I am sent, but I see you are a people who are ignorant." 23 So, when they saw it in the shape of a dense cloud approaching their valleys, they exclaimed, "This is only a heavy cloud which will bring us [welcome] rain!" [But Hud said]: "By no means! It is the very thing which you sought to hasten -- a wind bearing grievous suffering 24 Destroying everything by command of its Lord. And they became so that nothing was seen [of them] except their dwellings. Thus do We recompense the criminal people. 25 And verily We had empowered them with that wherewith We have not empowered you, and had assigned them ears and eyes and hearts; but their ears and eyes and hearts availed them naught since they denied the revelations of Allah; and what they used to mock befell them. 26
