Hadith 4006
وَعَن محمع بن جاريةَ قَالَ: قُسِمَتْ خَيْبَرُ عَلَى أَهْلِ الْحُدَيْبِيَةِ فَقَسَمَهَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ثَمَانِيَةَ عَشَرَ سَهْمًا وَكَانَ الْجَيْشُ أَلْفًا وَخَمْسَمِائَةٍ فِيهِمْ ثَلَاثُمِائَةِ فَارِسٍ فَأُعْطِيَ الْفَارِسُ سَهْمَيْنِ وَالرَّاجِلُ سَهْمًا رَوَاهُ أَبُو دَاوُدَ وَقَالَ: حَدِيثُ ابْنِ عُمَرَ أصح فَالْعَمَل عَلَيْهِ وَأَتَى الْوَهْمُ فِي حَدِيثِ مُجَمِّعٍ أَنَّهُ قَالَ: أَنَّهُ قَالَ: ثَلَاثُمِائَةِ فَارِسٍ وَإِنَّمَا كَانُوا مِائَتَيْ فَارس
Mujammi' b. Jariya said:Khaibar was divided among those who had been at al-Hudaibiya, and God’s Messenger divided it into eighteen portions. The army was one thousand five hundred of which three hundred were cavalry, and he gave two shares to a horseman and one to a footman. Abu Dawud transmitted it, saying Ibn ‘Umar’s tradition is sounder, and it is the one which is followed. The error in the tradition of Mujammi’ was because he said three hundred horsemen when there were only two hundred.
