Musnad Ahmad 33:836

Muhammad ibn Sabiq narrated to us, Ibrahim ibn Tahman narrated to us, from Abu al-Zubayr, from Jabir ibn Abdullah, that he said: "Allah, the Almighty and Majestic, granted Khaybar as spoils to the Messenger of Allah, may Allah bless him and grant him peace. The Messenger of Allah, may Allah bless him and grant him peace, confirmed them [the Jews] as they were, and divided it between himself and them. He sent Abdullah ibn Rawahah, and he estimated the yield for them. Then he said to them: 'O assembly of Jews, you are the most hateful of creation to me; you killed the prophets of Allah, the Almighty and Majestic, and you lied about Allah. However, my hatred for you does not compel me to be unjust toward you. I have estimated twenty thousand wasqs of dates; if you wish, it is yours, and if you refuse, it is mine.' They said: 'By this, the heavens and the earth stand. We have accepted, so leave us.'"
