Zubayr Ibn al-Awaam رضي الله عنه
(S94)
Aisha رضي الله عنها wrote letters to the leaders of the cities in Shaam, Koofa, Yamamah and Madinah explaining what happened in Basra. The only survivor from the Khawaarij was Harkoos Ibn Zuhayr.
When Ali رضي الله عنه was leaving Madinah for Koofa, Abdullah Ibn Salaam رضي الله عنه said do not go to Iraq, they will kill you. Ali رضي الله عنه replied: by Allah سُبْحَانَهُ وتَعَالَى, the Messenger ﷺ already told me of this.
Ali رضي الله عنه praised the Companions رضي الله عنهم as follows: He said he is being tested with Aisha, the most obedient of people. With Zubayr, the toughest. With Talha, the most genius and with Ya’la رضي الله عنهم, the most cooperative.
