۞ 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 but they said, "Have you come to us to turn us away from our deities? Then bring down upon us what you threaten us with, if you are 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 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 which will destroy everything at its Lord's behest!" And in the morning there was nothing left to be seen save their [empty] dwellings: thus We repay the evil-doers. 25 And We had established them in that wherein We have not established you, and We appointed for them hearing, and sight, and hearts; and yet their hearing, their sight and their hearts availed them nothing, since they denied the signs of God, and they were encompassed by that they mocked at. 26
