Musnad Ahmad 1423

It was narrated that "Abdullah bin az-Zubair (رضي الله عنه) said: On the day of al-Ahzab, "Umar bin Abi Salamah and I were put with the women. I looked out and saw az-Zubair on his horse, coming and going from Banu Quraizah two or three times. When he came back I said: “O my father, I saw you coming and going.” He said: “Did you see me, O my son?” I said: “Yes.” He said: “The Messenger of Allah (ﷺ) said: "Who would like to go to Banu Quraizah and bring me news of them?" So I set out and when I came back, the Messenger of Allah (ﷺ) mentioned both his father and his mother for me and said: "May my father and mother be sacrificed for you.”
