all enemy forces. Aftermath: Siege Of Banu Qurayza Following the retreat of the Confederate army, the Banu Qurayza neighborhoods were besieged by the Muslims. After a 25-day siege of their neighborhood, the Banu Qurayza unconditionally surrendered. When the Banu Qurayza tribe surrendered, the Muslim army seized their stronghold and their possessions for their acts. On the request of the Banu Aus, who were allied to the Qurayza, Muhammad chose one of them, Sa'ad ibn Mu'adh, as an arbitrator to pronounce judgment upon them. Sa'ad, who later died of his wounds from the battle, decreed the sentence, in which some of the men fighters shall be killed and some of their women and children enslaved. Muhammad approved of this decision, and the next day the sentence was carried out. The men – numbering between 400 and 900 – were bound and placed under the custody of Muhammad ibn Maslamah, while the women and children were placed under Abdullah ibn Salam, a former rabbi who had converted to Islam. Ibn Ishaq describes the killing of the Banu Qurayza men as follows: A lot of scholars have however cast doubt on ibn Ishaq's account and there is no reliable hadith about the exact number of people killed leading some to argue only prominent ones were executed. A number of individuals were spared when various Muslims intervened on their behalf. Several accounts note Muhammad's companions as executioners, Umar and Zubayr ibn al-Awwam in particular, and that each clan of the Aws was also charged with killing a group of Qurayza men. According to Ibn Ishaq's biography of Muhammad, one woman who had thrown a millstone from the battlements during the siege and killed one of the Muslim besiegers, was also beheaded along with the men. 'Ã'isha, one of Muhammad's wives, is cited as describing the woman as laughing and chatting with her during the massacre, down to the moment her name was called out: 'By Allah,' she said,' that is me.' I said to her 'You poor soul, what is to happen to you?' She said: "I must be killed." "Why?" I asked her. "For something I did," she answered. She went away and was beheaded for her acts. By Allah,('Ã'isha adds) I shall never forget her cheerfulness and her great laugh when she knew that she was to be killed.'Muir (p. 277) (Ibn Ishaq, Biography of Muhammad).
