Sahih Bukhari | Volume 3 | Hadith Number 485

Narrated by Abdullah bin Umar
Allah's Apostle gave the land of Khaibar to the Jews to work on and cultivate and take half of its yield. Ibn 'Umar added, "The land used to be rented for a certain portion (of its yield)." Nafi mentioned the amount of the portion but I forgot it. Rafi' bin Khadij said, "The Prophet forbade renting farms." Narrated 'Ubaid-Ullah Nafi' said: Ibn 'Umar said: (The contract of Khaibar continued) till 'Umar evacuated the Jews (from Khaibar).
