Sahih al-Bukhari, Volume 5, Book 59, Hadith 475 (USC-MSA) ⓘ
Narrated Jabir bin `Abdullah: On the day of Al-Hudaibiya, Allah's Messenger said to us' "You are the best people on the earth!" We were 1400 then. If I could see now, I would have shown you the place of the Tree (beneath which we gave the Pledge of Allegiance)." Salim said, "Our number was 1400."
حَدَّثَنَا عَلِيٌّ، حَدَّثَنَا سُفْيَانُ، قَالَ عَمْرٌو سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ قَالَ لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ الْحُدَيْبِيَةِ " أَنْتُمْ خَيْرُ أَهْلِ الأَرْضِ " . وَكُنَّا أَلْفًا وَأَرْبَعَمِائَةٍ، وَلَوْ كُنْتُ أُبْصِرُ الْيَوْمَ لأَرَيْتُكُمْ مَكَانَ الشَّجَرَةِ. تَابَعَهُ الأَعْمَشُ سَمِعَ سَالِمًا سَمِعَ جَابِرًا أَلْفًا وَأَرْبَعَمِائَةٍ.

وَقَالَ عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ مُرَّةَ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي أَوْفَى ـ رضى الله عنهما ـ كَانَ أَصْحَابُ الشَّجَرَةِ أَلْفًا وَثَلاَثَمِائَةٍ، وَكَانَتْ أَسْلَمُ ثُمْنَ الْمُهَاجِرِينَ. تَابَعَهُ مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا أَبُو دَاوُدَ حَدَّثَنَا شُعْبَةُ.
