Jabir (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) said on the day of the Battle of the Trench: "Who will bring me news of the enemy's army?" (By enemy here is meant Banu Qurayza.) Zubair (may Allah be pleased with him) said, "I will." The Prophet (peace and blessings be upon him) asked again: "Who will bring me news of the enemy's army?" This time also Zubair (may Allah be pleased with him) said, "I will." Upon this, the Prophet (peace and blessings be upon him) said: "Every prophet has disciples (true helpers), and my disciple is Zubair."
