Mukhtasar Bukhari

Narrated Abdullah bin Zubair (may Allah be pleased with him): I and Umar bin Abi Salama (due to our young age) were left among the women. Then I looked and saw that Zubair (may Allah be pleased with him) was mounted on his horse and went to and came from the Jews of Banu Qurayza two or three times. When I returned, I said, "O father! I saw you going to and coming from Banu Qurayza (what was the matter)?" He said, "Son, did you see me?" I said, "Yes." He said, "The Messenger of Allah (peace and blessings be upon him) said: 'Is there anyone who will go to Banu Qurayza and bring us their news?' So I went and (brought the news). When I returned, the Prophet (peace and blessings be upon him) gathered both my mother and father for me and said: 'May my parents be sacrificed for you.'"
