۞ And remember the fellowman of the tribe of A’ad; when he warned his nation in the Ahqaf* – and indeed Heralds of warning passed away before and after him – that, “Do not worship anyone except Allah; indeed I fear the punishment of a Great Day upon you. (* A country among sand dunes.) 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 'Allah alone has the knowledge' he said, 'I am sent to deliver to you the Message. But I can see that you are ignorant people' 23 Then, when they saw the (Penalty in the shape of) a cloud traversing the sky, coming to meet their valleys, they said, "This cloud will give us rain!" "Nay, it is the (Calamity) ye were asking to be hastened!- A wind wherein is a Grievous Penalty! 24 Destroying everything by the Command of its Lord! So they became such that nothing could be seen except their dwellings! Thus do We recompense the people who are Mujrimun (polytheists, disbelievers, sinners, etc.)! 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
