۞ 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 They said: "Have you come to turn us away from our gods? Then bring upon us what you predict for us, if you are a man of truth." 22 'Allah alone has the knowledge' he said, 'I am sent to deliver to you the Message. But I can see that you are ignorant people' 23 Then, when they saw it as a sudden cloud coming towards their valleys, they said, 'This is a cloud, that shall give us rain!' 'Not so; rather it is that you sought to hasten -- a wind, wherein is a painful chastisement, 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 And We had firmly established them in a (prosperity and) power which We have not given to you (ye Quraish!) and We had endowed them with (faculties of) hearing, seeing, heart and intellect: but of no profit to them were their (faculties of) hearing, sight, and heart and intellect, when they went on rejecting the Signs of Allah; and they were (completely) encircled by that which they used to mock at! 26
