Yunus (10:38)
أَمۡ یَقُولُونَ ٱفۡتَرَىٰهُۖ قُلۡ فَأۡتُوا۟ بِسُورَةࣲ مِّثۡلِهِۦ وَٱدۡعُوا۟ مَنِ ٱسۡتَطَعۡتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمۡ صَـٰدِقِینَ
Or say they: He hath invented it? Say: Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful.
— Mohammed Marmaduke William Pickthall
