It is not ˹possible˺ for this Quran to have been produced by anyone other than Allah. In fact, it is a confirmation of what came before, and an explanation of the Scripture. It is, without a doubt, from the Lord of all worlds.
Or do they claim, “He1 made it up!”? Tell them ˹O Prophet˺, “Produce one sûrah like it then, and seek help from whoever you can—other than Allah—if what you say is true!”
