'Abdullah b. Zubair reported on the Day of the Battle of the Trench:

I and Umar b. 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 b. 'Urwa reported from Abdullah b. 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, Allah's Messenger (ﷺ) addressed me saying: I would sacrifice for you my father and my mother.

حَدَّثَنَا إِسْمَاعِيلُ بْنُ الْخَلِيلِ، وَسُوَيْدُ بْنُ سَعِيدٍ، كِلاَهُمَا عَنِ ابْنِ مُسْهِرٍ، قَالَ إِسْمَاعِيلُ أَخْبَرَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، قَالَ كُنْتُ أَنَا وَعُمَرُ بْنُ أَبِي سَلَمَةَ، يَوْمَ الْخَنْدَقِ مَعَ النِّسْوَةِ فِي أُطُمِ حَسَّانٍ فَكَانَ يُطَأْطِئُ لِي مَرَّةً فَأَنْظُرُ وَأُطَأْطِئُ لَهُ مَرَّةً فَيَنْظُرُ فَكُنْتُ أَعْرِفُ أَبِي إِذَا مَرَّ عَلَى فَرَسِهِ فِي السِّلاَحِ إِلَى بَنِي قُرَيْظَةَ ‏.‏ قَالَ وَأَخْبَرَنِي عَبْدُ اللَّهِ بْنُ عُرْوَةَ عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ قَالَ فَذَكَرْتُ ذَلِكَ لأَبِي فَقَالَ وَرَأَيْتَنِي يَا بُنَىَّ قُلْتُ نَعَمْ ‏.‏ قَالَ أَمَا وَاللَّهِ لَقَدْ جَمَعَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَئِذٍ أَبَوَيْهِ فَقَالَ ‏

‏ فِدَاكَ أَبِي وَأُمِّي ‏
