I asked him what gave him the knowledge of the rule of the Christians such as he possessed. Then he brought in the people whom he had put out before, and of them he shewed me four of the greatest lords, and he told me that he had sent them in the guise of merchants with precious stones, into every country where Christians dwelt, to see their customs and how they were serving Christ. And he himself spake the French language to me, and said that it was thus that tidings of the Christians came to him, and of their lands, and that men were ready to become Christians owing to the excellence of their law; but they flinch owing to the badness with which the Christians fulfil it. And he said that the Saracens well fulfil the law which Mahomet gave them in the Koran, and which Gabriel brought to him. And that Gabriel used often to converse with Mahomet and tell him perfectly the will of God.
