"Kerim," said Noor ad Deen, "what thou hast told me is very singular; I never heard that a poor fisherman, as thou art, had any correspondence with a king?" "Be not astonished at that," replied the caliph: "you must know, that we both studied together under the same masters, and were always the best friends in the world: it is true, fortune has not been equally favourable to us; she has made him a king, and me a fisherman. But this inequality has not lessened our friendship. He has often expressed a readiness and desire to advance my fortune, but I always refused; and am better pleased with the satisfaction of knowing that he will never deny me whatever I ask for the service and advantage of my friends: let me do it, and you shall see the success."
