۞ 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 delude us away from our gods? Then bring us what you promise us, if you should be of the truthful." 22 He said, "Only God has the knowledge (of the coming of such torment). I preach to you the message that I have brought, but I can see that you are an ignorant people". 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 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 We had established them firmly in a manner We have not established you. We had given them ears and eyes and hearts. But nothing availed them -- neither their ears, nor their eyes, nor their hearts, for they denied the Signs of Allah. Then what they had mocked at encompassed them. 26
