Abu Al-Qasim Ali Ibn Husain Al-Sharif Al-Murtadha (d. 436 A.H), known as Sayyid Al-Murtadha, was one of the most renowned scholars of his time. After the death of Sheikh Mufid and his brother Sayyid Radhi, Sayyid Murtadha shouldered the governmental responsibilities by leading the Shi‘a society. He was the head of high court of justice who led the Alawites and supervised the hajj pilgrimage.
