Sīstānī, ʻAlī al-Ḥusaynī

Ali al-Husayni al-Sistani (Arabic: علي الحسيني السيستاني; born 4 August 1930) is an Islamic scholar and the dean of the Hawza in Najaf, Iraq. A Grand Ayatollah, Sistani is considered one of the leading religious leaders of Twelver Shia Muslims. After the invasion of Iraq and the subsequent overthrow of the authoritarian Baathist regime, Sistani advocated for democratization instead of the system of Wilayat al-Faqih. He has likewise endorsed rule of law, Iraqi nationalism, non-sectarianism and popular sovereignty. He has been a vocal critic of foreign interference in Iraqi affairs and has warned foreign actors against imposing their will on the Iraqi people. Born in Mashhad, Iran to a Sayyid family, Sistani studied in Qom under Hossein Borujerdi and later in Najaf under Abu al-Qasim al-Khu'i. An Usuli, Sistani rose to the rank of mujtahid in 1960 and succeeded Abd al-A'la al-Sabziwari as Grand Ayatollah. Sistani was included in top positions of The Muslim 500: The World's Most Influential Muslims from 2004 to 2024 and named one of the 100 most influential people in the world by Time magazine in 2004 and 2005.
