۞ Tell of the brother of 'Ad; when he warned his people in the sand dunes -- and indeed warners came and went before him and after him -- saying, "Worship none but God; surely I fear for you the punishment of an awful Day," 21 They said, “Have you come to us in order to turn us away from our Gods? Therefore bring upon us what you promise us, if you are 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 Then, when they saw it as a dense cloud coming towards their valleys, they said: "This is a cloud bringing us rain!" Nay, but it is that (torment) which you were asking to be hastened! a wind wherein is a painful torment! 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
