۞ Recount to them the story of (Hud), the brother of (the tribe of) 'Ad. Hud warned his people beside the sand-dunes -- and there have been other warners before him and since his time -- saying: “Serve none but Allah. Verily I fear that the chastisement of an awesome day shall come upon you.” 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 said, "Knowledge [of its time] is only with Allah, and I convey to you that with which I was sent; but I see you [to be] a people behaving ignorantly." 23 And so, when they beheld it in the shape of a dense cloud approaching their valleys, they exclaimed, "This is but a heavy cloud which will bring us [welcome] rain!" [But Hud said:] "Nay, but it is the very thing which you [so contemptuously] sought to hasten - a wind bearing grievous suffering, 24 bound to destroy everything at its Sustainer's behest!" And then they were so utterly wiped out that nothing could be seen save their [empty] dwellings: thus do We requite people lost in sin. 25 And We had certainly established them in such as We have not established you, and We made for them hearing and vision and hearts. But their hearing and vision and hearts availed them not from anything [of the punishment] when they were [continually] rejecting the signs of Allah; and they were enveloped by what they used to ridicule. 26
