Musannaf Ibn Abi Shaybah 39589 — The Battle of the Trench

Hisham narrates from his father that the Messenger of Allah (peace and blessings be upon him) said on the day of the Trench: "What man will go and bring us news of Banu Qurayzah?" Sayyiduna al-Zubayr (may Allah be pleased with him) rode off and brought news of Banu Qurayzah. Then he (peace and blessings be upon him) repeated this and said three times: "Who will bring me news of them?" Sayyiduna al-Zubayr said: "Yes!" The narrator says: The Prophet (peace and blessings be upon him) mentioned both his parents together for Sayyiduna al-Zubayr, saying: "May my father and mother be ransomed for you." And he (peace and blessings be upon him) said to Sayyiduna al-Zubayr: "Every prophet has a close disciple (hawari), and my close disciple is al-Zubayr, the son of my paternal aunt."
