One of al-Modarresi's main teachers was Mirza Mahdi al-Isfahani (d. 1945), the founding father of the tafkiki school of jurisprudence in its new manifestation.
Over there he established a library, and one of the most interesting books in his collection was a hand-written copy of Nahj al-Balagha, written by Muhammad bin Ali al-Hamdani in October, 1179.
[14] Some of his most notable students included: Al-Modarresi married the daughter of grand Ayatollah Mirza Mahdi al-Shirazi in Karbala.
Al-Modarresi died of heart failure in the early hours of April 5, 1994 in Tehran, whilst he was performing Fajr prayer.
