أَمۡ يَقُولُونَ ٱفۡتَرَىٰهُۖ قُلۡ فَأۡتُواْ بِسُورَةٖ مِّثۡلِهِۦ وَٱدۡعُواْ مَنِ ٱسۡتَطَعۡتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ
Am yaqooloonaf taraahu qul fa'too bi sooratin mislihee wad'oo manis tata'tum min doonil laahi in kuntum saadiqeen
Or do they say, "He forged it"? say: "Bring then a Sura like unto it, and call (to your aid) anyone you can besides Allah, if it be ye speak the truth!"
— Yunus (يُونُس), 10:38
