the regime. Following that, he was prosecuted by the (SAVAK) and was sentenced to death penalty for four times by an absence ballot. This situation forced him to a clandestine emigration to Mecca in 1961 where he succeeded to increase his struggle against the regime. Thereafter he lectured against the Shah during Hajj performance and was consequently imprisoned at Mecca owing to joint conspiracy of shah and the Saudi regime but after the protest of 04 prominent scholars of Iran and Iraq was released. After his release he migrated to Najaf in order to coach people in educative and Quranic revolution. Sadly enough he could not stay more than ten years in Najaf where his activities for bringing about political Quranic revolution accelerated and finally was forced to leave for Lebanon where he stayed for five years and then proceeded to Mecca again and during two years' stay he continued to impart knowledge of Quranic interpretation and jurisprudence. He was the second Shi'a scholar to impart knowledge in the "Masjidul - Haram" after Ayatullah Bahrul - Uloom. He occupied an eminent pulpit behind the "Maqam-e Ibrahim" where more than six hundred students from various Islamic countries attended his lectures. Although the education imparted by him did not last long, nevertheless he arranged peaceful debates with the Scholars of Mecca and Madina and convinced all of them by his strong Quranic arguments. Finally, he was arrested again and exiled from Mecca owing to his educative and political activities and returned to Beirut. After his three months' stay in Beirut and 71 years of exile from Iran he returned to uphold the revolution and aid Ayatullah Khomeini in establishment of the Islamic Republic. A few months after triumph of Islamic Revolution, he arrived back in Qom for teaching Quran and Jurisprudence. His lectures were wholly based on the Quran, uninfluenced by view points of any scholar except in the case there is no contradiction with the Quran. He has about 110 works on various subjects. His main Quranic work is an exegesis titled Tafsir Alforqan (in three volumes). Ayatullah Allama Tabataba'i.e., the most famous exegete of Quran wrote a commendation for it saying: "This exegesis is our glory and honour." He also published critique books on the Bible such as Aqaidona (our beliefs), Al - Moqarinat, and Rasool - ul - Islam. He was an authority in all fields of Islamic studies
