28:49
قُلۡ فَأۡتُوا۟ بِكِتَـٰبࣲ مِّنۡ عِندِ ٱللَّهِ هُوَ أَهۡدَىٰ مِنۡهُمَاۤ أَتَّبِعۡهُ إِن كُنتُمۡ صَـٰدِقِینَ
Say (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye are truthful.
— Mohammed Marmaduke William Pickthall
