2:23
وَإِن كُنتُمۡ فِی رَیۡبࣲ مِّمَّا نَزَّلۡنَا عَلَىٰ عَبۡدِنَا فَأۡتُوا۟ بِسُورَةࣲ مِّن مِّثۡلِهِۦ وَٱدۡعُوا۟ شُهَدَاۤءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَـٰدِقِینَ
And if ye are in doubt concerning that which We reveal unto Our slave (Muhammad), then produce a surah of the like thereof, and call your witness beside Allah if ye are truthful.
— Mohammed Marmaduke William Pickthall
