۞ 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, 'What, hast thou come to pervert us from our gods? Then bring us that thou promisest us, if indeed thou speakest truly.' 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 Then, when they saw the (Penalty in the shape of) a cloud traversing the sky, coming to meet their valleys, they said, "This cloud will give us rain!" "Nay, it is the (Calamity) ye were asking to be hastened!- A wind wherein is a Grievous Penalty! 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 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
