[4][5] The Islamic prophet Muhammad had found out that the People of Fadak had collected in order to fight the Muslims alongside the Khaybar Jews.
[6] The people of Fadak surrendered without a fight, and pleaded for a peace treaty in exchange for giving away half their land and wealth to Mohammed.
[13][14] After the Khaybar Jews surrendered to Muhammad and, having lost their only source of livelihood, they requested him to employ them back on their properties for half the share of the crop.
So Muhammad made some conciliation to the Khaybar Jews by re-engaging them in their lost land, but on condition that he reserved the right to banish them any time he wished.
Imam Ahmad recorded that `Umar said, "The wealth of Bani An-Nadir was of the Fai' type that Allah awarded His Messenger and for which the Muslims did not have to use cavalry or camelry.
The Banu an-Nadir property was kept wholly for his emergent needs, Fadak for travellers, and Khaybar was divided by the Apostle of Allah (peace_be_upon_him) into three sections: two for Muslims, and one as a contribution for his family.
