۞ 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 'Have you come to turn us away from our gods (they replied)? If what you say is true then bring down that which you promise us' 22 He said: "The Knowledge (of when it will come) is only with Allah: I proclaim to you the mission on which I have been sent: But I see that ye are a people in ignorance!".. 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 "Everything will it destroy by the command of its Lord!" Then by the morning they - nothing was to be seen but (the ruins of) their houses! thus do We recompense those given to sin! 25 We had strengthened them as We have not strengthened you, had given them ears and eyes and hearts; but nothing stood them in good stead, neither their ears nor eyes nor hearts, for they rejected the signs of God, and were seized by what they had mocked. 26
