Scholarly opinions
He has many opinions in different domains of Islamic learning like usul al fiqh, logic and fiqh.
Usul al-fiqh
One of his innovations in the domain of usul is to present new divisions on the subjects of Usul. According to the school of thought of his master, Muhammad Husein Isfahani, Muzaffar believes in new orderness on the subjects. For instance, before him, the subject of Ishtighagh has to discuss in the partition of alfaz not introductions. As a result, he divided subjects into four categories: alfaz, rational discussion, hujjat, usul Amaliyyah.
