۞ And make mention (O Muhammad) of the brother of A'ad when he warned his folk among the wind-curved sandhills - and verily warners came and went before and after him - saying: Serve none but Allah. Lo! I fear for you the doom of a tremendous 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 with Allah only. I convey unto you that wherewith I have been sent, but I see you are a folk that know not. 23 So when they saw the punishment coming towards their valleys, spread like a cloud on the horizon, they said, “That is a cloud which will shower rain upon us”; said Hud “In fact this is what you were being impatient for; a windstorm carrying a painful punishment.” 24 “That destroys all things by the command of its Lord” – so at morning none could be seen except their empty houses; this is the sort of punishment We mete out to the guilty. 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
