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 aliha (gods)? Then bring us that with which you threaten us, if you are one of the 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 So, when they saw it in the shape of a dense cloud approaching their valleys, they exclaimed, "This is only a heavy cloud which will bring us [welcome] rain!" [But Hud said]: "By no means! It is the very thing which you sought to hasten -- a wind bearing grievous suffering 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 established them in that wherein We have not established you, and We appointed for them hearing, and sight, and hearts; and yet their hearing, their sight and their hearts availed them nothing, since they denied the signs of God, and they were encompassed by that they mocked at. 26
