۞ And remember the brother of Ad, when he warned his people beside the sand-dunes -- and already warners had passed away alike before him and behind him -- saying, 'Serve none but God! Truly I fear for you the chastisement of a dreadful day. 21 'Have you come to turn us away from our gods (they replied)? If what you say is true then bring down that which you promise us' 22 He said: "The Knowledge (of when it will come) is only with Allah: I proclaim to you the mission on which I have been sent: But I see that ye are a people in ignorance!".. 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 It will destroy everything by the will of its Lord" (Not very long after) nothing could be seen of them except their dwellings. Thus do We recompense the sinful people. 25 We had empowered them to an extent which We have not empowered you, [O people of later times]; and We had endowed them with hearing, and sight, and hearts: but neither their hearing, nor their sight, nor their hearts were of the least avail to them, since they went on rejecting God's revelations; and they were overwhelmed by the very thing which they had been wont to deride. 26
