Answer
The answer is al-Awwam. Ibn al-Zubayr's father was al-Awwam ibn Khuwaylid. He belonged to the prominent Banu Asad clan of the Quraysh tribe in Mecca. Al-Awwam participated in several significant events during the early history of Islam, including the Battle of Badr in 624, where he fought against the Prophet Muhammad. Later on, he embraced Islam and became a loyal companion of the Prophet.
