Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Jews of Banu Qurayza agreed to the decision of Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him), (meaning whatever decision he would make, they would accept it). The Noble Prophet (peace and blessings be upon him) sent a message to Sayyiduna Sa'd (may Allah be pleased with him), so he came riding on a donkey, and when he reached near the mosque, the Noble Prophet (peace and blessings be upon him) said: "Stand up for your leader (and help him dismount from the donkey)." Then he said: "O Sa'd! These Jews of Banu Qurayza have agreed to your decision." He said: "I decide that their warriors be killed and their children (and women) be taken captive." The Noble Prophet (peace and blessings be upon him) said: "O Sa'd, you have indeed given the decision which is the decision of Allah, the Sovereign."

In one narration, it is stated that Sayyiduna Abu Sa'id (may Allah be pleased with him) reports: When Sayyiduna Sa'd (may Allah be pleased with him) appeared, the Noble Prophet (peace and blessings be upon him) said: "Stand up towards your leader and bring him down." Sayyiduna 'Umar (may Allah be pleased with him) said: "Our leader and master is Allah, the Exalted." Nevertheless, the Prophet (peace and blessings be upon him) said: "Bring him down." So they brought him down, and the Prophet (peace and blessings be upon him) said: "O Sa'd! Decide regarding them." ... .
