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.
‘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.
