Musnad Ahmad 1409

It was narrated that "Abdullah bin az-Zubair said: On the day of al-Khandaq, "Umar bin Abi Salamah and I were in the fort where the wives of the Messenger of Allah (ﷺ) were, the fort of Hassan. He would lift me up and I would lift him up. When he lifted me up, I saw my father go past on his way to Quraizah, as he was fighting alongside the Messenger of Allah (ﷺ) on the day of al-Khandaq. He said: “Who will go to Banu Quraizah and fight them?” I said to him when he came back: “O my father, I recognized you when you were going to Banu Quraizah.” He said: “O my son, by Allah, the Messenger of Allah(ﷺ) mentioned both his parents together for me when he said: May my father and mother be sacrificed for you."
