Al-Hakim ( / alḥakīm / wise one or doctor ), a term used to describe the polymath scientists and philosophers who played a central role in the development of Science in medieval Islam.

Al-Hakim is an important figure in a number of Shia Ismaili religions, such as the world's 15 million Nizaris and in particular the 2 million Druze of the Levant whose eponymous founder Ad-Darazi proclaimed him as the incarnation of God in 1018.

* 1021: the ruling Fatimid Caliph Al-Hakim bi-Amr Allah disappears suddenly, possibly assassinated by his own sister Sitt al-Mulk, which leads to the open persecution of the Druze by Ismaili Shia ; the Druze proclaimed that Al-Hakim went into hiding ( ghayba ), whereupon he would return as the Mahdi savior.

There were, however, exceptions to this general attitude of tolerance, most notably Al-Hakim bi-Amr Allah although this has been highly debated, with Al-Hakim's reputation among medieval Muslim historians conflated with his role in the Druze faith.

Muhammad bin Ismail Nashtakin ad-Darazi () was an 11th-century Ismaili preacher and early leader of the Druze faith who was labeled a heretic in 1016 and subsequently executed by the Fatimid Caliph Al-Hakim bi-Amr Allah.

During this stage a dispute occurred between ad-Darazi and Hamza bin Ali mainly concerning ad-Darazi's ghuluww ( Arabic, " exaggeration "), which refers to the belief that God was incarnated in human beings, especially ' Ali and his descendants, including Al-Hakim bi-Amr Allah who was the current Caliph, and ad-Darazi naming himself " The Sword of the Faith " which led Hamza to write an epistle refuting the need for the sword to spread the faith and several epistles refuting the beliefs of the ghulat.

Al-Hakim preferred Hamza ibn ' Ali ibn Ahmad over him and Ad-Darazi was executed in 1018, leaving Hamza the sole leader of the new faith

A fundamental change occurred when the Fatimid Caliph attempted to push into Syria in the later half of the 10th century, here they were faced with the now Turkish dominated forces of the Abbasid Caliph and began to realize the limits of their current military, thus during the reign of Abu Mansur Nizar al-Aziz Billah and Al-Hakim bi-Amr Allah the Caliph began incorporating armies of Turks and later Black Africans ( even later, other groups such as Armenians were also used ).

Al-Jam ` e Al-Anwar (, Anwar Mosque, literally: The Enlightened Mosque ) also Al-Hakim Mosque is a major Islamic religious site in Cairo, Egypt.

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 ).

The subsequent eruption of war between Iraq and ( largely Shia ) Iran led to an ever-increasing distrust of Iraq's Shia population by the ruling Ba ' ath party ; combined with his previous arrests, this convinced Al-Hakim that it was impossible to continue his Shia advocacy in Iraq, and in 1980 he fled to Iran.

Al-Hakim was killed on August 29, 2003, when a massive car bomb exploded as he left the Imam Ali Mosque in Najaf.

The fact that his assassination came in the midst of a pattern of violence against Shia clerics in Najaf in the weeks leading up to his death ( Al-Hakim was the fourth to be assassinated ) led some to conclude that the attack was most likely motivated by anti-Shia sentiment.

In the 11th century, a man allegedly sent by the Fatimid Caliph Al-Hakim bi-Amr Allah attempted to smash the Black Stone, but was killed on the spot, having caused only slight damage.
