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.‏

On the day of Al-Hudaibiya, Allah's Messenger (ﷺ) 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 thePledge of Allegiance)." Salim said, "Our number was 1400."
