۞ Remember Aad's brother who warned his nation in (the valley of) Al Ahqaf. Warners had already preceded and succeeded him saying: 'Worship none except Allah! (he said) 'Indeed, I fear for you the punishment of a Dreadful 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: "Only God has the knowledge. I only convey to you what I have been sent with. But I see you are a foolish people." 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 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 verily We had empowered them with that wherewith We have not empowered you, and had assigned them ears and eyes and hearts; but their ears and eyes and hearts availed them naught since they denied the revelations of Allah; and what they used to mock befell them. 26
