Superiority of divine revelation over human speech

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ

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."
