۞ And remember (Hud) the brother of 'Ad, when he warned his people in Al-Ahqaf (the curved sand-hills in the southern part of Arabian Peninsula). And surely, there have passed away warners before him and after him (saying): "Worship none but Allah; truly, I fear for you the torment of a mighty 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, "God alone knows when it will come, and I deliver to you the message with which I am sent, but I see you are a people who are ignorant." 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 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 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
