As Najaf is famous with Shiite Islamic religious schools and Arabic literature, Al-Waeli studied under prominent religious figures. He learned lecturing through a group of Islamic lecturers including Sayyid Baqir Slaimoun. He gained great admiration from his teachers through his intelligence, articulation, and presentation style. Ayatollah Imam Khomeini called him “"the Islamic Library"” as he was spreading his rich knowledge as well as lecturing the philosophy of Islamic jurisprudences in different places. Likewise, Grand Ayatollah Abul-Qassim Khoei called him ""the Tongue of Shia"" as his voice represents Shia ideology. One of his common messages in his lectures is that the differences between Shia and Sunnah jurisprudences should not create tension between the two sects since both sects ultimately have the same goal (which is getting closer to Allah). He repeatedly conveys that each sect has his own Ijtihad (interpretation of Hadith) but that should not create tension. He always condemned those whom called Shia non-Muslims.
