On the day of the battle of the Trench, the Prophet ﷺ wanted somebody from amongst the people to volunteer to be a reconnoitre. Az-Zubair volunteered. He demanded the same again and Az-Zubair volunteered again. Then he repeated the same demand (thrice) and AzZubair volunteered once more. The Prophet ﷺ then said, " Every prophet has a disciple and my disciple is Az-Zubair."  

سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ؓ يَقُولُ نَدَبَ النَّبِيُّ ﷺ النَّاسَ يَوْمَ الْخَنْدَقِ فَانْتَدَبَ الزُّبَيْرُ ثُمَّ نَدَبَهُمْ فَانْتَدَبَ الزُّبَيْرُ ثُمَّ نَدَبَهُمْ فَانْتَدَبَ الزُّبَيْرُ قَالَ النَّبِيُّ ﷺ إِنَّ لِكُلِّ نَبِيٍّ حَوَارِيًّا وَحَوَارِيَّ الزُّبَيْرُ قَالَ سُفْيَانُ الْحَوَارِيُّ النَّاصِرُ  

from the Prophet ﷺ the following Hadith (No. 242). Narrated Ibn ʿUmar: The Prophet ﷺ said, "If the people knew what I know about traveling alone, then nobody would travel alone at night."  

عَنِ النَّبِيِّ ﷺ حَدَّثَنَا أَبُو نُعَيْمٍ حَدَّثَنَا عَاصِمُ بْنُ مُحَمَّدِ بْنِ زَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ عَنْ أَبِيهِ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ قَالَ لَوْ يَعْلَمُ النَّاسُ مَا فِي الْوَحْدَةِ مَا أَعْلَمُ مَا سَارَ رَاكِبٌ بِلَيْلٍ وَحْدَهُ
