Sayyid Ayatollah Mohammad Baqir al-Hakim (1939 – 29 August 2003; Arabic: ??? ???? ???? ???????), also known as Shaheed al-Mehraab, was a senior Iraqi Shia cleric and the leader of the Supreme Council for Islamic Revolution in Iraq (SCIRI).
Al-Hakim spent more than 20 years in exile in Iran and returned to Iraq on 12 May 2003.
Al-Hakim was a contemporary of Ayatollah Khomeini, and The Guardian compared the two in terms of their times in exile and their support in their respective homelands.
After his return to Iraq, al-Hakim's life was in danger because of his work to encourage Shiite resistance to Saddam Hussein and from a rivalry with Ayatollah Muqtada al-Sadr, the son of the late Ayatollah Mohammed Sadeq al-Sadr, who had himself been assassinated in Najaf in 1999.
Al-Hakim was assassinated in a bomb attack in Najaf in 2003 when aged 63 years old.
The bombing may have been carried out by a member of Saddam's regime (Ba'ath), with the attack coming as al-Hakim was leaving the shrine of Imam Ali.
At least 75 others in the vicinity also died in the bombing.
