۞ 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 us to turn us away from our gods; then bring us what you threaten us with, if you are of the truthful ones. 22 He said: "Only God has the knowledge. I only convey to you what I have been sent with. But I see you are a foolish people." 23 Then, when they beheld it as a dense cloud coming toward their valleys, they said: Here is a cloud bringing us rain. Nay, but it is that which ye did seek to hasten, a wind wherein is 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 wherein We have not established you, and We appointed for them hearing, and sight, and hearts; and yet their hearing, their sight and their hearts availed them nothing, since they denied the signs of God, and they were encompassed by that they mocked at. 26
