۞ And mention the brother of Ad; when he warned his people in the sandy plains,-- and indeed warners came before him and after him-- saying Serve none but Allah; surely I fear for you the punishment of a grievous 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, "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 When they saw the scourge advancing towards their valleys, they said: “This is a cloud that will bring much rain to us.” “By no means; it is what you had sought to hasten -- a wind-storm bearing a grievous chastisement 24 destroying everything by the commandment of its Lord.' So in the morning there was naught to be seen but their dwelling-places. Even so do We recompense the people of the sinners. 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
