Abu Sa'id Khudri, may Allah be pleased with him, narrates: When Banu Qurayza agreed to accept the decision of Sa'd, may Allah be pleased with him, the Messenger of Allah, peace and blessings be upon him, sent someone to him, and he was nearby. So he came riding on a donkey, and when he reached near the mosque, the Messenger of Allah, peace and blessings be upon him, said to the Ansar: "Stand up for your leader." Agreed upon. And this hadith has already been mentioned in full in the chapter on the ruling of captives.
