Surah Al-Baqarah — Al-Baqarah 2:23
وَإِن كُنتُمۡ فِي رَيۡبٖ مِّمَّا نَزَّلۡنَا عَلَىٰ عَبۡدِنَا فَأۡتُواْ بِسُورَةٖ مِّن مِّثۡلِهِۦ وَٱدۡعُواْ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَٰدِقِينَ
And if you are in doubt about what We have revealed to Our servant, then produce a sûrah like it and call your helpers other than Allah, if what you say is true.
