Dawud :: Book 19 : Hadith 3006
Narrated A Group of Companions of the Prophet:
Bashir ibn Yasar, the client of the Ansar, reported on the authority of a group of the Companions of the Prophet (peace_be_upon_him): When the Apostle of Allah (peace_be_upon_him) conquered Khaybar, he divided it into thirty-six lots, each lot comprising one hundred portions. One half of it was for the Apostle of Allah (peace_be_upon_him) and for the Muslims; and he separated the remaining half for the deputations which came to him, other matters and emergent needs of the people.
