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

Narrated Qatada: 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 (PBUH) on the day of Al-Hudaibiya.' Translation Not Available
