۞ 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 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 When they saw the torment as a cloud proceeding to their valleys, they said, "This cloud will bring us rain." He said, "No, it is the torment which you wanted to suffer immediately. It is a wind bearing and painful torment. 24 Destroying everything by the command of its Lord, so they became such that naught could be seen except their dwellings. Thus do We reward the guilty people. 25 And certainly We had established them in what We have not established you in, and We had given-- them ears and eyes and hearts, but neither their ears, nor their eyes, nor their hearts availed them aught, since they denied the communications of Allah, and that which they mocked encompassed them. 26
