[Machine] Zaid ibn Thabit witnessed the Battle of Bu'ath when I was only six years old. This happened five years before the migration of the Messenger of Allah, peace be upon him. The Messenger of Allah, peace be upon him, arrived in Medina when I was eleven years old. I was brought to the Messenger of Allah, peace be upon him, and they said, "This is a young boy from the Khazraj tribe who has memorized sixteen surahs." However, I was not allowed to participate in the Battle of Badr or Uhud. But I was allowed to participate in the Battle of the Trench.  

زَيْدُ بْنُ ثَابِتٍ كَانَتْ وَقْعَةُ بُعَاثَ وَأَنَا ابْنُ سِتِّ سِنِينَ وَكَانَتْ قَبْلَ هِجْرَةِ رَسُولِ اللَّهِ ﷺ بِخَمْسِ سِنِينَ فَقَدِمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ وَأَنَا ابْنُ إِحْدَى عَشْرَةَ سَنَةً وَأُتِيَ بِي إِلَى رَسُولِ اللَّهِ ﷺ فَقَالُوا غُلَامٌ مِنَ الْخَزْرَجِ قَدْ قَرَأَ سِتَّ عَشْرَةَ سُورَةً فَلَمْ أُجَزْ فِي بَدْرٍ وَلَا أُحُدٍ وَأُجَزْتُ فِي الْخَنْدَقِ
