Abu Dawud Book 8, Hadith Number 2730.
Narated By Mujammi’ ibn Jariyah al-Ansari : Mujammi’ was one of the Qur’an-reciters (qaris), and he said: We were present with the Apostle of Allah (PBUH) 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 (PBUH). We also proceeded with the people, galloping (our camels). We found the Prophet (PBUH) standing on his riding-animal at Kura’ al-Ghamim.
When the people gathered near him, he recited: “Verily We have granted thee a manifest victory.
A man asked: Is this a victory, Apostle 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 Apostle of Allah (PBUH) 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.
