Sayyiduna Jabir (may Allah be pleased with him) says: Allah Almighty gave (the land of) Banu al-Nadir to His Messenger as spoils, and the Messenger of Allah (peace and blessings be upon him) left them as they were and made it (the produce) shared between himself and them. Then he (peace and blessings be upon him) sent Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him), who made the estimate. Then he said to them: "O community of Jews! You are the most hateful of people to me; you killed the prophets of Allah and lied against Allah. No, my hatred for you does not lead me to wrong you. I have estimated your dates at twenty thousand wasqs. If you wish, take it, and if you refuse, then it is mine." They said: "By this the heavens and the earth stand firm." Then they said: "We have taken it, so leave us."
