‘Umar said that the properties of the B. an-Nadir were part of what God bestowed on His Messenger from what the Muslims had not ridden on horses or camels to get; so they belonged specially to God’s Messenger who gave his family their annual contribution, then applied what remained for weapons and horses as equipment in God’s path.
Malik b. Aus b. al-Hadathan reported "Umar b. al-Khattab as saying that God appointed His Messenger a special portion in this fai’* which He gave to no other. He then recited, “What God has bestowed on His Messenger from them . . . omnipotent" (Al-Qur’an; 59:6). This was purely for God’s Messenger who used to give his family their annual contribution from this property, then take what remained and deal with it as he did with God’s property.
*Fai’ is the term used for tribute from territory the Muslims have conquered.
When the fai’ came to God's Messenger he divided it that day, giving two portions to a married man and one to a bachelor. I was summoned and he gave me two portions, for I had a family; then ‘Ammar b. Yasir was summoned after me and given one.
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.
