۞ And mention, [O Muhammad], the brother of 'Aad, when he warned his people in the [region of] al-Ahqaf - and warners had already passed on before him and after him - [saying], "Do not worship except Allah. Indeed, I fear for you the punishment of a terrible day." 21 They said: Have you come to us to turn us away from our gods; then bring us what you threaten us with, if you are of the truthful ones. 22 He said, 'Knowledge is only with God, and I deliver to you the Message with which I was sent; but I see you are an 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 destroying everything by the commandment of its Lord.' So in the morning there was naught to be seen but their dwelling-places. Even so do We recompense the people of the sinners. 25 And certainly We had established them in what We have not established you in, and We had given-- them ears and eyes and hearts, but neither their ears, nor their eyes, nor their hearts availed them aught, since they denied the communications of Allah, and that which they mocked encompassed them. 26
