۞ 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 replied: “Allah alone knows about this. I only convey to you the Message that I have been sent with. But I see that you are an ignorant people.” 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 will destroy everything by the command of its Lord.” Thereafter nothing was left to be seen except their dwellings. Thus do We requite the wrong-doers. 25 We had strengthened them as We have not strengthened you, had given them ears and eyes and hearts; but nothing stood them in good stead, neither their ears nor eyes nor hearts, for they rejected the signs of God, and were seized by what they had mocked. 26
