At fifteen, she married her cousin, Haj Seyyed Muhammad Amin al-Tujjar, who was a famous businessman in Isfahan.
A few years after her wedding, at the age of twenty, she started to study Islamic sciences, such as Fiqh, Usul, tafsir, hadith and hikma, with a private teacher, Ayatollah Mir Muhammad Najafabadi, who tutored her at home.
This work reached the howza al-'ilmiyah (traditional religious education centre) of Najaf in Iraq, and was warmly approved by the 'Ulama.
Indeed, after several written examinations from the greatest `ulama of Najaf in Islamic sciences such as fiqh (jurisprudence), hadith (traditions), or Qur'an, she was given permission of Ijtihad (the application of reason to the solution of legal issues) and Istenbat-e ahkam-e shar'i (deduction of the main rules of conduct).
A great number of `ulama used to visit Banu Amin for the purpose of discussing scientific and spiritual subjects.
