After the death of Mohammad Bagher Sabzevari, for more than 50 years, a number of clerics were appointed as Shaykh al-Islām of Isfahan (kind of religious leader). At the beginning of Nader Shah's rule and his coming to power, two spiritual positions, namely Imam of Congregational Prayer and Shaykh al-Islam, were in the monopoly of the descendants of Mohammad-Baqer Majlesi. Some advisers told Nader Shah that the two positions, which have power, influence and importance among the masses, should not be concentrated in one place where they can oppose the government whenever they want.
