It has been narrated by Buraida who heard it from his father that he joined the Messenger of Allah ﷺ in sixteen military campaigns

وَحَدَّثَنِي أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا مُعْتَمِرُ بْنُ سُلَيْمَانَ، عَنْ كَهْمَسٍ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، أَنَّهُ قَالَ غَزَا مَعَ رَسُولِ اللَّهِ ﷺ سِتَّ عَشْرَةَ غَزْوَةً .
