Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him) reports from the Prophet (peace and blessings be upon him) that on the day of the Conquest of Makkah he gave him the banner of Sayyiduna Sa'd bin Ubadah (may Allah be pleased with him), so Sayyiduna al-Zubayr (may Allah be pleased with him) entered Makkah with two banners.
Abu Ya'la recorded it, and its chain contains a narrator, Muhammad bin al-Hasan bin Zabalah, who is extremely da'if (weak).
