After completing intermediate studies, he joined the advanced jurisprudence classes (Dars-e Kharij) of Ayatollah Sheikh Abdolkarim Ha’eri.

• Ayatollah Seyyed Musa Shubayri Zanjani:

"Mohagheghi taught a unique class combining modern knowledge with seminary studies—even Sheikh Abdol-Javad Jebel Ameli (our Lam'ah instructor) attended."

• Seyyed Hossein Badla:

"Mohagheghi possessed both traditional and modern knowledge. I recall how he voluntarily taught at secular schools to educate youth."

• Ayatollah Fazel Lankarani:

"When Ayatollah Borujerdi sought a qualified envoy to Europe, I proposed Mohagheghi—a pious, eloquent university professor well-versed in contemporary sciences. After meeting Borujerdi, he succeeded brilliantly in Hamburg, establishing its iconic mosque."

• In the 1940s (1320s SH), Hemmat Mosque lacked a permanent Imam until Mohagheghi accepted the role.

• Later, at Borujerdi’s request, he departed for Germany in 1950 (1329 SH) to oversee European Muslim affairs.

• His successor, Hojatoleslam Mahmoud Ardakani (son-in-law of Ayatollah Fazel Lankarani), relocated to Tajrish for health reasons but soon transferred to Fatimiyah Mosque, leaving Hemmat without a permanent Imam again.

Passed away in 1970 (1349 SH) at age 58 and was buried in Abu Hossein Cemetery, Qom.
