۞ 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: 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 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 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 yet, We had established them securely in a manner in which We have never established you, [O people of later times;] and We had endowed them with hearing, and sight, and [knowledgeable] hearts: but neither their hearing, nor their sight, nor their hearts were of the least avail to them, seeing that they went on rejecting God's messages; and [in the end] they were overwhelmed by the very thing which they had been wont to deride. 26
