۞ And remember thou the brother of the Aad when We warned his people in the sandhills - and surely there have passed away warners before him and after him - saying: worship none save Allah, verily 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, “Its knowledge is only with Allah; and I convey to you the messages of my Lord, but I perceive that you are an ignorant nation.” 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 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 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
