In the field of literature and `Ilm al-Usul , he studied under Shaykh Muhammad Taha al-Huwayzi and could distinguish himself in these fields as well as in poetry. Simultaneously, he studied the preliminary studies of jurisprudence ( sutuh ) and other fields of religious studies under other mentors, in all of which he excelled. Having finished the preliminary stage, Shaykh al-Muzaffar applied himself to higher studies in jurisprudence, `Ilm al-Usul , and philosophy.
He, along with his younger brother Muhammad Husayn, attended the classes of his brother Shaykh Muhammad Hasan. He also joined the classes of Shaykh Agha Aiya' al-Din al-`Iraqi in the field of `Ilm al-Usul , and the classes of Shaykh Mirza Muhammad Husayn al-Na'ini in the fields of jurisprudence and `Ilm al-Usul . He also studied, yet distinctively, the theses of Shaykh Muhammad Husayn al-Isfahani in the fields of jurisprudence, `Ilm al-Usul , and supreme theo-philosophy.
In these three fields of knowledge, Shaykh al-Muzaffar was much influenced by the opinions of Shaykh al-Isfahani, so he imitated his course of research in his book of ‘ Usul al-Fiqh in chaptering and indexing the fundaments of jurisprudence—a fact which the author has referred to in his introduction to this book. As is noticed from the accomplished parts of his book of ‘ Usul al-Fiqh ’, Shaykh al-Muzaffar acted upon his mentor’s private basics of jurisprudence.
He also had great regard for his mentor, al-Isfahani, and showered him with the most respectful words whenever he would refer to or mention him and show his love and admiration for him more than any other student who sincerely admired his mentor. This feeling towards his mentor and loyalty to him manifests itself to the reader from his writings in the introductions to his jurisprudential and philosophic books, theses, and essays, such as the introduction to his book of ‘ al-Asfar ’.
Shaykh al-Muzaffar also graduated under his mentors in jurisprudence, `Ilm al-Usul , and philosophy although he had his idiosyncratic views, inferences, and researches to which his mentors confessed. In the midst of all that and apart from his remarkable efforts in the schools and faculties of Muntada al-Nashr (Forum of Publishing), he engaged himself with teaching the highest levels of preliminary and higher education in the fields of jurisprudence, `Ilm al-Usul , and philosophy.
