Sadiq al-Shirazi

al-Shirazi was born in Karbala to Mirza Mahdi al-Shirazi, a grand ayatollah, and Halima al-Shirazi. Both of his parents are from the distinguished clerical al-Shirazi family that emigrated from Shiraz to Karbala in the 19th century. All of his brothers are clerics, and Muhamamad al-Shirazi is a marja'. His mother is the great-granddaughter of Mirza Shirazi, the pioneer of the Tobacco Movement. His nephew, Mohammad Taqi al-Modarresi is also a marja'.

On March 6, 2018, his son, Hussein was arrested reportedly by the IRGC as he appeared at the Special Clerical Court. He was prosecuted after a lecture comparing Iran's government—the Guardianship of the Islamic Jurist (velayat-e faqih)—to a regime of "pharaohs". His arrest fuelled debates on whether Iran's supreme leader Ali Khamenei should be able to claim divine sanction for unlimited state powers. Protests against his arrest were held at the Iranian consulate in Karbala, Basra and Najaf, Kuwait City and Iran's embassies in Baghdad and London. He was released on bail on March 18. In India, He is famous by the name of Rajjan Bhai for his welfare works.

After his brother, Muhammad passed away in 2001, he succeeded him as marja'.

In 1971, he was exiled from Iraq by the Baathist regime. He settled in Kuwait for a while with his older brother, Muhammad. Him and his family then migrated to Iran, after the Islamic revolution. He resumed classes under his brother, until he gained ijtihad, and began his own classes. He has been residing in Qom ever since he moved in 1980.

Grand Ayatollah Sayyid Sadiq al-Husayni al-Shirazi (Arabic: صادق الحسيني الشيرازي; Persian: سید صادق حسینی شیرازی; born August 20, 1942) is an Iraqi-Iranian Shia marja'.
