۞ 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, "Have you come to turn us away from our gods? Show us that with which you threaten us if you are truthful". 22 He said: The knowledge is with Allah only. I convey unto you that wherewith I have been sent, but I see you are a folk that know not. 23 So when they saw it as a cloud advancing towards their valleys, they said: "This is just a passing cloud that will bring us rain." "No. It is what you were trying to hasten: The wind which carries the grievous punishment! 24 It will destroy everything by the will of its Lord" (Not very long after) nothing could be seen of them except their dwellings. Thus do We recompense the sinful people. 25 And We had established them in that which We have not established you, and We made for them hearing, sight, and hearts, but their hearing, sight, and hearts did not help them a thing, because they disbelieved the signs of Allah. And what they mocked encompassed them. 26
