According to a story about the Prophet Mohammed, there lived next door to him a man who was very much opposed to the Prophet and spoke against him; and this man saw that the people to whom he spoke had belief in the Prophet, while nobody believed in him. Then years passed, and many believed and many gave their life for the message of the Prophet; and it so happened that eventually a great many people came from afar, thousands and thousands from different countries, to visit the Prophet. The same man still lived in the neighborhood, but he had never altered his opinion. And one day someone asked the Prophet, "Why does this man, who has known the day when nobody listened, when nobody followed you, but who now sees that thousands of people who come here are benefited and filled with bliss and joy and blessing, still continue to criticize you and to oppose you?" And the Prophet said, "His heart has become a fountain of obscurity; he produces from his own self the clouds which surround him; he cannot see." And he was sorry for him.
