It has been reported on the authority of Abu Zubair who heard Jabir b. Abdullah say: I fought in the company of the Messenger of Allah ﷺ nineteen battles. Jabir said: I did not participate in the Battle of Badr and the Battle of Uhud. My father prevented me (from participating in these battles as my age was tender). After 'Abdullah (my father) was killed on the Day of Ubud, I never lagged behind the Messenger of Allah ﷺ and joined every battle (he fought).

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا زَكَرِيَّاءُ، أَخْبَرَنَا أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ غَزَوْتُ مَعَ رَسُولِ اللَّهِ ﷺ تِسْعَ عَشْرَةَ غَزْوَةً - قَالَ جَابِرٌ - لَمْ أَشْهَدْ بَدْرًا وَلاَ أُحُدًا مَنَعَنِي أَبِي فَلَمَّا قُتِلَ عَبْدُ اللَّهِ يَوْمَ أُحُدٍ لَمْ أَتَخَلَّفْ عَنْ رَسُولِ اللَّهِ ﷺ فِي غَزْوَةٍ قَطُّ .
