I asked Jabir b. 'Abdullah about the number of the Companions (of the Prophet who took the oath of fealty under) the tree. He said: If we were a hundred thousand, it (i. e. the water in the well at Hudaibiya) would have sufficed us, but actually we were one thousand and five hundred.  

مسلم:١٨٥٦f – وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى وَابْنُ بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَمْرِو بْنِ مُرَّةَ عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ قَالَ سَأَلْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ عَنْ أَصْحَابِ الشَّجَرَةِ فَقَالَ
