Sahih Muslim | Book 10 | Hadith Number 3763

Narrated by Ibn Umar
Ibn Umar reported that 'Umar b. al-Khattab (Allah be pleased with him) expelled the Jews and Christians from the land of Hijaz, and that when Allah's Messenger (may peace be upon him) conquered Khaibar he made up his mind to expel the Jews from it (the territory of Khaibar) because, when that land was conquered, it came under the sway of Allah, that of His Messenger (may peace be upon him) and that of the Muslims. The jews asked Allah's Messenger (may peace be upon him) to let them continue there on the condition that they would work on it, and would get in turn half of the fruit (of the trees), whereupon Allah's Messenger (may peace be upon him) said: We would let you continue there so long as we will desire. So they continued (to cultivate the lands) till 'Umar externed them to Taima' ang Ariha (two villages in Arabia, but out of Hijaz).
