۞ 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 'Have you come to turn us away from our gods (they replied)? If what you say is true then bring down that which you promise us' 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 sudden cloud coming towards their valleys, they said, 'This is a cloud, that shall give us rain!' 'Not so; rather it is that you sought to hasten -- a wind, wherein is a painful chastisement, 24 that will destroy everything by the command of its Lord.” Thereafter nothing was left to be seen except their dwellings. Thus do We requite the wrong-doers. 25 And We had certainly established them in such as We have not established you, and We made for them hearing and vision and hearts. But their hearing and vision and hearts availed them not from anything [of the punishment] when they were [continually] rejecting the signs of Allah; and they were enveloped by what they used to ridicule. 26
