Sahih Bukhari | Volume 3 | Hadith Number 531

Narrated by Ibn 'Umar
Umar expelled the Jews and the Christians from Hijaz. When Allah's Apostle had conquered Khaibar, he wanted to expel the Jews from it as its land became the property of Allah, His Apostle, and the Muslims. Allah's Apostle intended to expel the Jews but they requested him to let them stay there on the condition that they would do the labour and get half of the fruits. Allah's Apostle told them, "We will let you stay on thus condition, as long as we wish." So, they (i.e. Jews) kept on living there until 'Umar forced them to go towards Taima' and Ariha'.
