Abdullah bin Zubair reported on the Day of the Battle of the Trench: I and Umar bin Abu Salama were with women folk in the fort of Hassan (b. Thabit). He at one time leaned for me and I cast a glance and at anothertime I leaned for him and he would see and I recognised my father as he rode on his horse with his arms towards the tribe of Quraizah. Abdullah bin Urwa reported fromAbdullah bin Zubair: I made a mention of that to my father, whereupon he said: My son, did you see me (on that occasion)? He said: Yes. Thereupon he said: By Allah, Allahs Messenger ﷺ addressed me saying: I would sacrifice for thee my father and my mother.
