Musannaf Ibn Abi Shayba 27:529

'Abd al-Rahim narrated to us, from Hisham ibn 'Urwah, from 'Urwah, that the Messenger of Allah (may Allah bless him and grant him peace) said on the day of the Trench: "Who is a man who will go and bring me news of Banu Qurayzah?" So al-Zubayr rode off and brought him their news. Then he returned, and he (the Prophet) said three times: "Who will bring me their news?" And al-Zubayr said: "Yes." He (the Prophet) gathered his parents for al-Zubayr and said: "May my father and mother be sacrificed for you." And he said regarding al-Zubayr: "Every prophet has a disciple, and my disciple is al-Zubayr, the son of my paternal aunt."
