۞ AND REMEMBER that brother of [the tribe of] Ad, how - seeing that [other] warnings had already come and gone within his own knowledge as well as in times beyond his ken - he warned his people [who lived] among those sand-dunes: "Worship none but God! Verily, I fear lest suffering befall you on an awesome day!" 21 They said, "Have you come to delude us away from our gods? Then bring us what you promise us, if you should be of the truthful." 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 When they saw the scourge advancing towards their valleys, they said: “This is a cloud that will bring much rain to us.” “By no means; it is what you had sought to hasten -- a wind-storm bearing a grievous chastisement 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 established them in that wherein We have not established you, and We appointed for them hearing, and sight, and hearts; and yet their hearing, their sight and their hearts availed them nothing, since they denied the signs of God, and they were encompassed by that they mocked at. 26
