۞ (Muhammad), recall the brother of the people of Ad, when he warned his people in the valley of al-ahqaf saying, "There existed many warners before and after him. Do not worship anything other than God. I am afraid for you about the torment of the great 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 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 which will destroy everything at its Lord's behest!" And in the morning there was nothing left to be seen save their [empty] dwellings: thus We repay the evil-doers. 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
