Narrated Qatada:
حَدَّثَنَا الصَّلْتُ بْنُ مُحَمَّدٍ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، عَنْ سَعِيدٍ ، عَنْ قَتَادَةَ ، قُلْتُ لِسَعِيدِ بْنِ الْمُسَيَّبِ بَلَغَنِي أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ ، كَانَ يَقُولُ كَانُوا أَرْبَعَ عَشْرَةَ مِائَةً. فَقَالَ لِي سَعِيدٌ حَدَّثَنِي جَابِرٌ كَانُوا خَمْسَ عَشْرَةَ مِائَةً الَّذِينَ بَايَعُوا النَّبِيَّ صلى الله عليه وسلم يَوْمَ الْحُدَيْبِيَةِ . تَابَعَهُ أَبُو دَاوُدَ حَدَّثَنَا قُرَّةُ عَنْ قَتَادَةَ
I said to Sa`id bin Al-Musaiyab, "I have been informed that Jabir bin `Abdullah said that the number (of Al-Hudaibiya Muslim warriors) was 1400." Sa`id said to me, "Jabir narrated to me that they were 1500 who gave the Pledge of allegiance to the Prophet (ﷺ) on the day of Al-Hudaibiya.'
