Abu Dawud
Tributes, Spoils And Rulership
Book Number: 013 / Hadith Number: 3008
Narated By Bashir ibn Yasar : When Allah bestowed Khaybar on the Apostle of Allah (pbuh) as fay' (spoils of war without fighting), he divided the whole into thirty six lots. He put aside a half, i.e. eighteen lots, for the Muslims. Each lot comprised one hundred shares, and the Prophet (pbuh) was with them. He received a share like the share of one of them.
The Apostle of Allah (pbuh) separated eighteen lots, that is, half, for his future needs and whatever befell the Muslims. These were al-Watih, al-Kutaybah, as-Salalim and their colleagues. When all this property came in the possession of the Prophet (pbuh) and of the Muslims, they did not have sufficient labourers to work on it. The Apostle of Allah (pbuh) called Jews and employed them on contract.
