Concept
Ali al-Husayni al-Sistani (علي الحسيني السيستاني; Ali-ye Hoseyni-ye Sistāni; born 4 August 1930), is a Twelver Shia Iranian–Iraqi Grand Ayatollah and marja'. One of the most senior scholars in Shia Islam, he has been described as the spiritual leader of Shia Muslims worldwide (as of 2003), "the undisputed leader of Iraq's Shias", included in top positions of "The Muslim 500: The World's Most Influential Muslims", from 2009 to 2023, and named one of the 100 most influential people in the world by Time magazine in 2004 and 2005. Sistani was born in either 1929 or 1930 in Mashhad, to a family of religious clerics who claim descent from Husayn ibn Ali, the grandson of Muhammad. His father was Mohammad-Baqir al-Sistani and his mother was the daughter of Ridha al-Mehrebani al-Sarabi. Sistani began his religious education as a child, first in Mashhad in his father's hawzah, and continuing later in Qom. In Qom he studied under Grand Ayatollah Hossein Borujerdi. Later in 1951, Sistani traveled to Iraq to study in Najaf under Grand Ayatollah Abu al-Qasim al-Khoei. Sistani rose to the rank of mujtahid in 1960 at thirty-one. When Khoei died in 1992, Abd al-A'la al-Sabziwari briefly became the leading marja'. However, when he died in 1993, al-Sistani ascended to the rank of Grand Ayatollah through formal peer recognition of his scholarship. His role as successor to Khoei was symbolically cemented when he led funeral prayers for Khoei, and he also inherited most of Khoei's network and following. During the years of Saddam Hussein's rule of Iraq through the Arab nationalist and Sunni dominated Baath Party, al-Sistani was untouched during the violent Baathist repression and persecution that killed many clerics including Mohammad al-Sadr in 1999, for which Saddam denied any involvement. Al-Sistani's mosque was forcefully shut down in 1994 and did not reopen until the 2003 US-led invasion of Iraq. Since the overthrow of the Baath Party of Iraq in 2003, Sistani has played an increasingly prominent role in regional religious and political affairs and he has been called the "most influential" figure in post-invasion Iraq.
