Banu Qurayza
Following the retreat of the Confederate army, the Banu Qurayza neighbourhoods were besieged by the Muslims. After a 25-day siege of their neighbourhood the Banu Qurayza unconditionally surrendered. When the Banu Qurayza tribe surrendered, the Muslim army seized their stronghold and their possessions. 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 would later die of his wounds from the battle, decreed the sentence, in which the men shall be killed and women and children enslaved. Muhammad approved of this decision, and the next day the sentence was carried out.
