The holy Quran is for human guidance and morality; when introducing outstanding figures, it does not stop at the level of the prophets, but it has explained other dominant figures leading people to happiness. Mo`men-e Al-e Yasin, called Habib Najjar in the Fariqain`s commentators, is one of these figures. He believed in the messengers when they arrived at his city and, when heard that people oppose the messengers, he advised the people kindly to believe in them. As mentioned in the holy Quran, he believed in God and the Judgment truly, avoid worshiping idols and being completely attracted to the prophet` message, supported them and finally martyred in the way. His valuable speeches are mentioned in the verses 20 to 27 of Yasin. The paper has studied his character, manner of life and the way in which he helped Jesus as understood by the holy Quran and Fariqain`s commentators.
