Narrated Abdullah bin Zubair (may Allah be pleased with him): On the occasion of the Battle of Ahzab, I and Umar bin Abi Salamah (may Allah be pleased with him) were left among the women (because both of us were children). Suddenly, I saw that Zubair (may Allah be pleased with him) (your father) was riding his horse, going towards Banu Qurayza (a tribe of Jews), and this happened two or three times. Then when he returned from there, I said, "Father! I saw you going and coming several times." He said, "Son! Did you really see that?" I replied, "Yes." He said, "The Messenger of Allah (peace and blessings of Allah be upon him) had said, 'Who will go to Banu Qurayza and bring me news of their movements?' So I went there, and when I returned with the information, the Messenger of Allah (peace and blessings of Allah be upon him), out of great happiness, mentioned both his parents together and said, 'May my father and mother be sacrificed for you.'"
