Ibn ‘Umar told that ‘Umar b. al-Khattab deported the Jews and the Christians from the land of the Hijaz and when God’s Messenger got supremacy over the people of Khaibar he intended to expel the Jews from it, for when the land was conquered it belonged to God, His Messenger and the Muslims. But the Jews asked God’s Messenger to leave them on condition that they should do all the cultivation and have half the produce, and he replied, “We shall confirm you on that condition as long as we wish.” So they were confirmed till ‘Umar deported them during his period of rule to Taima and Jericho. (Bukhari and Muslim.)
