۞ And remember the fellowman of the tribe of A’ad; when he warned his nation in the Ahqaf* – and indeed Heralds of warning passed away before and after him – that, “Do not worship anyone except Allah; indeed I fear the punishment of a Great Day upon you. (* A country among sand dunes.) 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, '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 So, when they saw it in the shape of a dense cloud approaching their valleys, they exclaimed, "This is only a heavy cloud which will bring us [welcome] rain!" [But Hud said]: "By no means! It is the very thing which you sought to hasten -- a wind bearing grievous suffering 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 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
