that the Messenger of Allah ﷺ said: "Indeed, every Prophet has a Hawari and, [indeed], my Hawari is Az-Zubair [bin Al-'Awwam]." And Abu Na'im added in it: "On the Day of Al-Ahzab, he ﷺ said: 'Who will bring us news about their party?' Az-Zubair said: 'I will.' He said it three times. Az-Zubair said (each time): 'I will.'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ لِكُلِّ نَبِيٍّ حَوَارِيًّا وَإِنَّ حَوَارِيَّ الزُّبَيْرُ بْنُ الْعَوَّامِ وَزَادَ أَبُو نُعَيْمٍ فِيهِ يَوْمَ الأَحْزَابِ قَالَ مَنْ يَأْتِينَا بِخَبَرِ الْقَوْمِ قَالَ الزُّبَيْرُ أَنَا قَالَهَا ثَلاَثًا قَالَ الزُّبَيْرُ أَنَا هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ  

"On the Day of (the battle of) Al-Jamal, Az-Zubair exhorted his son 'Abdullah, saying: 'There is not a part of me except that it has been injured while with the Messenger of Allah ﷺ,' until that ended with his private parts.  

أَوْصَى الزُّبَيْرُ إِلَى ابْنِهِ عَبْدِ اللَّهِ صَبِيحَةَ الْجَمَلِ فَقَالَ مَا مِنِّي عُضْوٌ إِلاَّ وَقَدْ جُرِحَ مَعَ رَسُولِ اللَّهِ ﷺ حَتَّى انْتَهَى ذَاكَ إِلَى فَرْجِهِ
