A third influence was of as-Sayyid Abu 'l-Qasim Ja'far (son of as-Sayyid Muhammad al-Musawi) Khwansari (1313/1895-6 - 1380/1961), known as “the mathematician.” al-`Allamah at-Tabataba'i was proud of learning the mathematics from him. Also, he wrote a book on some topics of higher mathematics, applying therein some special theories of his teacher. The book is mentioned in adh-Dhari `ah, vol, ii, pp. 232 - 233.
He learned philosophy and metaphysics from as-Sayyid Husayn (s/o as-Sayyid Rida s/o as-Sayyid Musa-) al-Husayni (1293/1876 - 1358/1939) of al-Badkubil a well-known teacher of philosophy and related subjects in those days.
In ethical and spiritual field, he received his training from his relatives, as-Sayyid (al-Mirza) `Ali Agha (s/o al-Mirza Husayn al-Qadi) Tabataba'i (1285/1869 - 1366/1947), a well-known divine who established a school of spiritual and ethical training which is flourishing to this day. All those influences combined in al-`Allamah at-Tabataba'i to create in him a well-balanced academic and spiritual personality.
A well-respected authority on religious subjects of jurisprudence and its fundamentals; a philosopher of independent views and various new theories; an inspired model of ethical and spiritual perfection, who not only taught morality but lived it - this was al-`Allamah at-Tabataba'i. Yet it will be correct to say that his scholarship was overshadowed by his fame and prestige as a philosopher and a spiritual man.
al-`Allamah at-Tabataba'i returned to Tabriz in 1353 (1934) where he was welcomed as a religous scholar. There he spent his time teaching higher philosophy to willing disciples - but it was a small place for his talents. In 1364 (1945) he migrated to Qum, the most important centre of religious education in Iran. In Qum, he remained engaged in imparting knowledge of ethics, philosophy and exegesis of the Qur'an to the students who had already attained to a high level of erudition.
There he remained till his death on Sunday, 18/1/1402 (15/11/1981). May Allah bestow His mercy on him. Amen. Many religious leaders of the present generation were and are among his students and disciples, the most famous being the late Murtada Mutahhari (1338/ 1920 - 1399/ 1979). al-`Allamah at Tabataba'i's fame rests on his various academic works - the , most important being his great exegesis of the Qur'an, al-Mizan fitafsiri'l-Qur'an.
