۞ 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: Hast come to turn us away from our gods? Then bring upon us that wherewith thou threatenest us, if thou art of the 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 And when they saw it as a cloud approaching their valleys, they said, "This is a cloud bringing us rain!" Rather, it is that for which you were impatient: a wind, within it a painful punishment, 24 It shall annihilate everything by the command of its Lord. Wherefore they became such that naught could be seen save their dwellings Thus We requite a nation of the culprits. 25 We had established them more firmly in the land than you are. We had given them ears, eyes, and hearts but none of their ears, eyes, and hearts proved to be of any benefit to them; they rejected the revelations of God and the torment which they mocked brought upon them utter destruction. 26
