Abu Ahmad Husayn bin Mousa the father of the two ever shinning start – Sayyid Murtada and Sayyid Radi – upon the sky of literature and knowledge, himself was one of the most honorable and distinguished personalities from the descendants of the Holy Prophet (S). He was a learned scholar, thinker and competent manager possessed with a unique sense of farsightedness. By practicing self-restraints and self-control in his actions and deeds, he was able to accumulate all the desired virtuous and righteous qualities within himself. During his period, he was famous for righteousness, truthfulness, faith, and sincerity and was respected by everybody.

His opinion was sought and welcomed by all sectors of public, kings and beggars’ scholars and illiterates, and elders and youngsters. For common people his opinion was tantamount to a Fatwa (religious decree) for all practical purposes. Because of his fame, Abu Nasr Firooz son of Ezzod-dowleh Delami famous as Bahaud-dowleh from the kings of Ale Buyeh dynasty bestowed upon him the titles of At-Tahir Al-Wahad (unique in righteous conduct) and Dhu’ l-Manaqib(possessor of all righteous virtues).

Because of his ingenuity and insight, the king appointed him for important public offices such as “Naqabati – Alviyan (Chief of the Alvites-affairs), Chief Justice of the Supreme Court”, and “Chief of the Protocol for the Hajj Pilgrims”. Of course, discharging such higher responsibilities requires large organizations consisting of competent managers and skilled manpower in order to accomplish the tasks in an excellent manner. But because of his special talents and trust in God-Almighty, he was able to perform all these difficult tasks alone with perfection and complete satisfaction. About his performance it is quoted: He (Abu Ahmad) never accepted any difficult task unless and until he was absolutely sure and confident that he would accomplish it satisfactorily.

Apart from this, he was a man of integrity and was trusted by the great religious and worldly personalities, and the confidential letters and recommendations between Abbasids Caliphs, Ale-Buyeh kings and rules of Damascus (ale-Hamdan) were exchanged through his good offices.
