۞ Remember Aad's brother who warned his nation in (the valley of) Al Ahqaf. Warners had already preceded and succeeded him saying: 'Worship none except Allah! (he said) 'Indeed, I fear for you the punishment of a Dreadful Day' 21 They answered: "Hast thou come to seduce us away from our gods? Bring, then, upon us that [doom] with which thou threaten us, if thou art a man of truth!" 22 He said: The knowledge is only with Allah, and I deliver to you the message with which I am sent, but I see you are a people who are ignorant. 23 Then, when they saw it as a dense cloud coming towards their valleys, they said: "This is a cloud bringing us rain!" Nay, but it is that (torment) which you were asking to be hastened! a wind wherein is a painful torment! 24 Destroying everything by command of its Lord. And they became so that nothing was seen [of them] except their dwellings. Thus do We recompense the criminal 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
