Narrated Abu Sa'id Al-Khudri (may Allah be pleased with him): When Banu Qurayza surrendered and came down from their fortress on the condition of arbitration by Sa'd bin Mu'adh (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) sent for him. He (Sa'd) was staying nearby (because he was wounded). Sa'd (may Allah be pleased with him) came riding on a donkey. When he approached the Prophet (peace and blessings be upon him), the Prophet said: "Stand up for your leader (and help him dismount)." So he dismounted and sat near the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "These people (Banu Qurayza) have surrendered on your arbitration, so give your judgment concerning them." He said: "My judgment is that all the men who fought should be killed, and their women and children should be taken as captives." The Prophet (peace and blessings be upon him) said: "You have judged according to Allah's command."
