۞ 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 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 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 It will destroy everything by the command of its Lord' And when morning came there was nothing to be seen except their dwellings. As such We recompense sinful people. 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
