Mukhtasar Bukhari (Abridged) 1233 — Virtue of spying on the enemy

Narrated Jabir (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said during the Battle of Ahzab, "Who will bring me news of the enemy?" Zubair (may Allah be pleased with him) said, "I will (bring it)." Then the Prophet (peace and blessings of Allah be upon him) again said, "Who will bring me news of the enemy?" He again said, "I (will bring it)." So the Prophet (peace and blessings of Allah be upon him) said, "Every prophet has a disciple, and my disciple is Zubair (may Allah be pleased with him)."
