۞ Tell of the brother of 'Ad; when he warned his people in the sand dunes -- and indeed warners came and went before him and after him -- saying, "Worship none but God; surely I fear for you the punishment of an awful Day," 21 They said: Hast come to turn us away from our gods? Then bring upon us that wherewith thou threatenest us, if thou art of the truthful. 22 He said, “Its knowledge is only with Allah; and I convey to you the messages of my Lord, but I perceive that you are an ignorant nation.” 23 Then, when they beheld it as a dense cloud coming toward their valleys, they said: Here is a cloud bringing us rain. Nay, but it is that which ye did seek to hasten, a wind wherein is painful torment, 24 It will destroy everything by the command of its Lord' And when morning came there was nothing to be seen except their dwellings. As such We recompense sinful people. 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
