He traces his paternal lineage to Habib ibn Muzahir Al-Asadi, and maternal to Al-Hurr Al-Riyahi, who she was a daughter of Hussein Khan  Donboli. His ancestors migrated from Tasuj to Khoy and settled there. They were known from around the 18th century for their interests in religious, linguistic and literary sciences. Muhammad Amin al-Imami was born in Najaf in 1303 AH/ 1885 AH when his father was a student in Iraq. His father returned to Khoy and Muhammad Amin was four years old.

He studied with Mohammed Kazem Yazdi, Abdallah Mazandarani, Hassan al-Sadr, Ahmad Shirazi, Ali Muhammad Najafabadi, Muhammad Kazim Khurasani and Fethullah Qa'ravi Isfahani.
