Musannaf Ibn Abi Shaybah 39600 — What I have preserved about Banu

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the people of Qurayzah surrendered on the judgment of Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him). The narrator says: He (peace and blessings be upon him) sent someone to Sayyiduna Sa'd (may Allah be pleased with him). Sayyiduna Sa'd (may Allah be pleased with him) came on a donkey. The narrator says: When Sayyiduna Sa'd (may Allah be pleased with him) drew near the mosque, he (peace and blessings be upon him) said: "Stand up for your leader," or he said: "the best man among you." Then he (peace and blessings be upon him) said: "These people have surrendered on your judgment." Sayyiduna Sa'd (may Allah be pleased with him) said: "Their fighting men should be killed, and their women and children taken captive." The narrator says: He (peace and blessings be upon him) said: "You have judged by the judgment of the King (al-Malik)." Sometimes the narrator reports the words: "You have judged by the judgment of Allah."
