Amr ibn Jarmuz
Amr ibn Jurmuz was a soldier of caliph Ali, who assassinated Zubayr ibn al-Awwam shortly after the Battle of the Camel, after Zubayr withdrew from the army before the battle began due to a hadith that Caliph Ali ibn Abi Talib had reminded him with regards to what Muhammad had said to Zubayr: “You will rise up in a battle against Ali ibn Abi Talib”.
