أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ
Am yaqooloonaf taraahu qul faatoo bisooratim mislihee wad'oo manis tata'tum min doonil laahi in kuntum saadiqeen
Or do they say, "He has invented it"? Say, "Then bring a sura like it, and call on anyone you can besides God, if you are truthful."
