۞ And mention the brother of Ad; when he warned his people in the sandy plains,-- and indeed warners came before him and after him-- saying Serve none but Allah; surely I fear for you the punishment of a grievous day. 21 They said: "Have you come to turn us away from our gods? Then bring upon us what you predict for us, if you are a man of truth." 22 He said, 'Knowledge is only with God, and I deliver to you the Message with which I was sent; but I see you are an ignorant people.' 23 Then, when they saw it as a dense cloud coming towards their valleys, they said: "This is a cloud bringing us rain!" Nay, but it is that (torment) which you were asking to be hastened! a wind wherein is a painful torment! 24 that will destroy everything by the command of its Lord.” Thereafter nothing was left to be seen except their dwellings. Thus do We requite the wrong-doers. 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
