۞ 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: 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 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 It will destroy everything at the bidding of its Lord." So in the morning there was nothing but their empty dwellings to be seen. That is how We requite the sinners. 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
