۞ And make mention (O Muhammad) of the brother of A'ad when he warned his folk among the wind-curved sandhills - and verily warners came and went before and after him - saying: Serve none but Allah. Lo! I fear for you the doom of a tremendous Day. 21 They said: "Have you come to turn us away from our aliha (gods)? Then bring us that with which you threaten us, if you are one of the truthful!" 22 He said: "Only God has the knowledge. I only convey to you what I have been sent with. But I see you are a foolish people." 23 When they saw the scourge advancing towards their valleys, they said: “This is a cloud that will bring much rain to us.” “By no means; it is what you had sought to hasten -- a wind-storm bearing a grievous chastisement 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 firmly in a manner We have not established you. We had given them ears and eyes and hearts. But nothing availed them -- neither their ears, nor their eyes, nor their hearts, for they denied the Signs of Allah. Then what they had mocked at encompassed them. 26
