Yunus · Ayah 38
أَمْ يَقُولُونَ ٱفْتَرَىٰهُ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَٰدِقِينَ
Or do they say [about the Prophet (ﷺ)], "He invented it?" Say, "Then bring forth a sūrah like it and call upon [for assistance] whomever you can besides Allāh, if you should be truthful."
