[custom_adv] Mohammad Baqir al-Hakim (1939 – 29 August 2003), also known as Shaheed al-Mehraab, was a senior Iraqi Shia cleric and the leader of the Supreme Council for Islamic Revolution in Iraq. He was assassinated in a bomb attack in Najaf in 2003. [custom_adv] Al-Hakim was born in Najaf in 1939 into the Hakim Family of Shiite religious scholars. He was the son of Muhsin al-Hakim and Fawzieh Hassan Bazzi. Al-Hakim was the uncle of Muhammad Sayid al-Hakim. [custom_adv] He co-founded the modern Islamic political movement in Iraq in the 1960s, along with Mohammad Baqir al-Sadr, with whom he worked closely until the latter's death in 1980. [custom_adv] Though not among the most hard-line of Islamists, Al-Hakim was seen as dangerous by the ruling Ba'ath regime, largely because of his agitation on behalf of Iraq's majority Shia population (the ruling regime was mostly Sunnis). [custom_adv] This led to his arrest in 1972, for promoting Nikah Mut'ah, a legal form of temporary marital relationship in the Shia sect, but he was released shortly thereafter.
