Then he stood and addressed the people, and said: O people, the Messenger of Allah ﷺ made a deal with the Jews of Khaibar on the basis that we could expel them whenever we want. They have attacked 'Abdullah bin ‘Umar and dislocated his arms, as you heard about their attack on the Ansari before him. We do not doubt that they are the ones who did it, as we have no other enemy but them. Whoever has property in Khaibar, let him go there, for I am going to expel the Jews. Then he expelled them.
