Narrated Mujammi' ibn Jariyah al-Ansari:

Mujammi' was one of the Qur'an-reciters (qaris), and he said: We were present with the Messenger of Allah (ﷺ) at al-Hudaybiyyah. When we returned, the people were driving their camels quickly. The people said to one another: What is the matter with them? They said: Revelation has come down to the Prophet (ﷺ). We also proceeded with the people, galloping (our camels). We found the Prophet (ﷺ) standing on his riding-animal at Kura' al-Ghamim. When the people gathered near him, he recited: "Verily We have granted you a manifest victory. A man asked: Is this a victory, Messenger of Allah? He replied: Yes. By Him in Whose hands the soul of Muhammad is, this is a victory. Khaybar was divided among those who had been at al-Hudaybiyyah, and the Messenger of Allah (ﷺ) divided it into eighteen portions. The army consisted of one thousand five hundred men, of which three hundred were cavalry, and he gave two shares to a horseman and one to a foot-soldier. Abu Dawud said: Abu Mu'awiyah's tradition is sounder, and it is one which is followed. I think the error is in the tradition of Mujammi', because he said: "three hundred horsemen." when there were only two hundred.

حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى، حَدَّثَنَا مُجَمِّعُ بْنُ يَعْقُوبَ بْنِ مُجَمِّعِ بْنِ يَزِيدَ الأَنْصَارِيُّ، قَالَ سَمِعْتُ أَبِي يَعْقُوبَ بْنَ مُجَمِّعٍ، يَذْكُرُ عَنْ عَمِّهِ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ الأَنْصَارِيِّ، عَنْ عَمِّهِ، مُجَمِّعِ بْنِ جَارِيَةَ الأَنْصَارِيِّ وَكَانَ أَحَدَ الْقُرَّاءِ الَّذِينَ قَرَءُوا الْقُرْآنَ قَالَ شَهِدْنَا الْحُدَيْبِيَةَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَمَّا انْصَرَفْنَا عَنْهَا إِذَا النَّاسُ يَهُزُّونَ الأَبَاعِرَ فَقَالَ بَعْضُ النَّاسِ لِبَعْضٍ مَا لِلنَّاسِ قَالُوا أُوحِيَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَخَرَجْنَا مَعَ النَّاسِ نُوجِفُ فَوَجَدْنَا النَّبِيَّ صلى الله عليه وسلم وَاقِفًا عَلَى رَاحِلَتِهِ عِنْدَ كُرَاعِ الْغَمِيمِ فَلَمَّا اجْتَمَعَ عَلَيْهِ النَّاسُ قَرَأَ عَلَيْهِمْ ‏{‏ إِنَّا فَتَحْنَا لَكَ فَتْحًا مُبِينًا ‏}‏ فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ أَفَتْحٌ هُوَ قَالَ ‏

‏ نَعَمْ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ إِنَّهُ لَفَتْحٌ ‏

‏ ‏.‏ فَقُسِّمَتْ خَيْبَرُ عَلَى أَهْلِ الْحُدَيْبِيَةِ فَقَسَّمَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى ثَمَانِيَةَ عَشَرَ سَهْمًا وَكَانَ الْجَيْشُ أَلْفًا وَخَمْسَمِائَةٍ فِيهِمْ ثَلاَثُمِائَةِ فَارِسٍ فَأَعْطَى الْفَارِسَ سَهْمَيْنِ وَأَعْطَى الرَّاجِلَ سَهْمًا ‏.‏ قَالَ أَبُو دَاوُدَ حَدِيثُ أَبِي مُعَاوِيَةَ أَصَحُّ وَالْعَمَلُ عَلَيْهِ وَأَرَى الْوَهَمَ فِي حَدِيثِ مُجَمِّعٍ أَنَّهُ قَالَ ثَلاَثُمِائَةِ فَارِسٍ وَكَانُوا مِائَتَىْ فَارِسٍ ‏.‏
