۞ 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 but they said, "Have you come to us to turn us away from our deities? Then bring down upon us what you threaten us with, if you are truthful." 22 He said: The knowledge is with Allah only. I convey unto you that wherewith I have been sent, but I see you are a folk that know not. 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 at the bidding of its Lord." So in the morning there was nothing but their empty dwellings to be seen. That is how We requite the sinners. 25 And indeed We had firmly established them with that wherewith We have not established you (O Quraish)! And We had assigned them the (faculties of) hearing (ears), seeing (eyes), and hearts, but their hearing (ears), seeing (eyes), and their hearts availed them nothing since they used to deny the Ayat (Allah's Prophets and their Prophethood, proofs, evidences, verses, signs, revelations, etc.) of Allah, and they were completely encircled by that which they used to mock at! 26
