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 اللهِ بْنِ الزُّبَيْرِ ، قَالَ: كُنْتُ أَنَا وَعُمَرُ بْنُ أَبِي سَلَمَةَ ، يَوْمَ الْخَنْدَقِ مَعَ النِّسْوَةِ فِي أُطُمِ حَسَّانَ ، فَكَانَ يُطَأْطِئُ لِي مَرَّةً فَأَنْظُرُ ، وَأُطَأْطِئُ لَهُ مَرَّةً فَيَنْظُرُ ، فَكُنْتُ أَعْرِفُ أَبِي إِذَا مَرَّ عَلَى فَرَسِهِ فِي السِّلاَحِ ، إِلَى بَنِي قُرَيْظَةَ.قَالَ : وَأَخْبَرَنِي عَبْدُ اللهِ بْنُ عُرْوَةَ ، عَنْ عَبْدِ اللهِ بْنِ الزُّبَيْرِ ، قَالَ: فَذَكَرْتُ ذَلِكَ لأَبِي فَقَالَ: وَرَأَيْتَنِي يَا بُنَيَّ ؟ قُلْتُ : نَعَمْ ، قَالَ: أَمَا وَاللَّهِ لَقَدْ جَمَعَ لِي رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، يَوْمَئِذٍ أَبَوَيْهِ ، فَقَالَ: فَدَاكَ أَبِي وَأُمِّي.

It was narrated that 'Abdullah bin Az-Zubair said: "On the Day of Al-Khandaq, 'Umar bin Abi Salamah and I were with the women in the fort of Hassan. Sometimes he would squat down for me to (climb on his shoulders and) look, and sometimes I would squat down for him to (climb on my shoulders and) look. And I recognized my father when he passed by on his horse with his weapons, heading towards Banu. Quraizah." "He said: ''Abdullah bin 'Urwah informed me that 'Abdullah bin Az-Zubair said: 'I mentioned that to my father and he said: "Did you see me, 0 my son?" I said: "Yes." He said: "By Allah, on that day the Messenger of Allah (s.a.w) mentioned both his parents for me, and he said: 'May my father and mother be ransomed for you."'
