Hud Ayah 13

أَمْ يَقُولُونَ ٱفْتَرَٮٰهُ‌ۖ قُلْ فَأْتُواْ بِعَشْرِ سُوَرٍ مِّثْلِهِۦ مُفْتَرَيَـٰتٍ وَٱدْعُواْ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ ١٣ Or do they say, “He has fabricated this ?Quran?!”? Say, ?O Prophet,? “Produce ten fabricated sûrahs like it and seek help from whoever you can—other than Allah—if what you say is true!”
