Ayatollah Montazeri was his classmate in this period.Later, Motahhari emigrated to Isfahan because of hot climate of Qom. There he became familiar with Haj Ali Agha Shirazi who was the teacher of Nahj al-Balagha in 1320 (Solar Hijri calendar) whom Motahhari always described with honor. Later, he joined the University of Capital, where he taught philosophy for 22 years. Between 1965 and 1973 he also gave regular lectures at the Hosseiniye Ershad .
