Zubayr ibn al-Awwam

Al-Zubayr ibn al-Awwam ibn Khuwaylid al-Asadi (Arabic: الزُّبَيْر بْن الْعَوَّام بْن خُوَيْلِد الأَسَدِيّ, romanized: Al-Zubayr ibn al-ʿAwwām ibn Khuwaylid al-ʾAsadī; c. 594–656) was an Arab Muslim commander in the service of the Islamic prophet Muhammad, his first cousin and brother-in-law, and caliphs Abu Bakr (r. 632–634) and Umar (r. 634–644).

An early convert to Islam, Zubayr was a commander in the Battle of Badr in 624, in which the latter was instrumental in defeating the opponent forces of the Quraysh. He participated in almost all of the early Muslim battles and expeditions under Muhammad. In the Battle of the Trench, due to his military service, Muhammad bestowed the title Hawari Rasul Allah ('Disciple of the Messenger of God') upon him. After Muhammad's death, Zubayr was appointed a commander in the Ridda Wars by caliph Abu Bakr. He was involved in the defense of Medina and the Battle of Yamama. During Umar's reign, Zubayr served in the Muslim conquests of Egypt, Levant, Persia, Sudan, and Tripolitania.

After Umar's assassination, Zubayr became an important political figure of the caliphate, being the chief advisor of the Shura that elected the third caliph Uthman. During the latter's caliphate, Zubayr advised the caliph on political and religious issues. After Uthman was assassinated, Zubayr pledged allegiance to the fourth caliph Ali, though later withdrew allegiance, after Ali refused to avenge Uthman's death. Zubayr's forces engaged with Ali's forces in the Battle of the Camel in December 656. In the aftermath, while Zubayr was prostrating in prayer, he was killed by Amr ibn Jarmuz.

Zubayr is generally considered by historians to be one of early Islam's most accomplished commanders. The Sunni Islamic tradition credits Zubayr with being promised paradise. The Shia Islamic tradition views Zubayr negatively. The general's descendants, known as the Zubayrids, are found worldwide.
