Grand Ayatollah Sayyid Muhammad-Sadiq Husayni Rohani (Persian: محمد صادق حسینی روحانی; b. 1926) is an Iranian Shia marja'. Rohani currently resides in Qom. He claims to have gained ijtihad from the grand Ayatollah Abu al-Qasim al-Khoei, at the age of 25. He announced his marja'iyya after the death of grand Ayatollah Hossein Borujerdi, at the age of 35. Rohani was one of the first senior clerics to be placed under house arrest under direct order from grand Ayatollah Ruhollah Khomeini just a few years after the Iranian revolution. Rohani remains a critic of the Iranian government today.
