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 وَعَن حبيب بن مسلَمةَ الفِهْريِّ قَالَ شَهِدْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نفل الرّبع فِي البدأة وَالثلث فِي الرجمة. رَوَاهُ أَبُو دَاوُد

Mujammaʿ ibn Jariya reported: Khaybar was divided among the people of al-Hudaybiya. The Messenger of God (peace and blessings be upon him) divided it into eighteen shares. The army numbered one thousand five hundred, including three hundred horsemen. A horseman was given two shares, and a foot soldier one share. Narrated by Abu Dawud, who said: ‘The hadith of Ibn ʿUmar is more authentic, and it is acted upon. The error in the hadith of Mujammaʿ is that it says there were three hundred horsemen; they were actually two hundred.’ Habib ibn Maslama al-Fihri reported: I witnessed the Prophet (peace and blessings be upon him) grant an extra quarter at the beginning of an expedition and a third on the return journey. Narrated by Abu Dawud.
Notes and open questions — unreviewed
The source first gives three hundred horsemen, then Abu Dawud identifies that number as an error and says there were two hundred. Its second report's terms for departure and return are rendered descriptively.
