Ayatollah Taheri-Isfahani was born in 1926 in Isfahan, Iran. He was a restless opposition to the regime of Shah, and greatly contributed to the victory of Islamic revolution. Upon the request of Ayatollah Khomeini, he launched Friday prayers in Isfahan before the victory of Islamic revolution in 1979, and restated the Friday prayer Imam of Isfahan by Ayatollah Khomeini after the revolution. He was also elected a member of the Assembly of Experts from Isfahan. However, he resigned from his position as Friday prayer Imam in 2002 to show his disagreement of the Islamic regime. He is considered a reformist Ayatollah, who has continuously challenged the policies and attitude of the Islamic regime.
