Grand Ayatollah Sayed M. Ali Tabatabai lived in London, United Kingdom, and delivered speeches in his home. The Sayed also visited Shia Islamic centres and Hussainiyyas around Europe and London, including Masjid Al-Muhassin - the mosque of Sheikh Yasser Al-Habib, where the congregation, including Sheikh Yasser Al-Habib, would pray behind him. Sayed M. Ali Tabatabai is amongst the Shia Maraje who have given the Ijaza (scholarly licence) to Sheikh Yasser Al-Habib, attesting to Sheikh Yasser Al-Habib being a Mujtahid (i.e. at the level of Ijtihad).
