۞ AND REMEMBER that brother of [the tribe of] Ad, how - seeing that [other] warnings had already come and gone within his own knowledge as well as in times beyond his ken - he warned his people [who lived] among those sand-dunes: "Worship none but God! Verily, I fear lest suffering befall you on an awesome 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 'Allah alone has the knowledge' he said, 'I am sent to deliver to you the Message. But I can see that you are 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 "Everything will it destroy by the command of its Lord!" Then by the morning they - nothing was to be seen but (the ruins of) their houses! thus do We recompense those given to sin! 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
