Sayyiduna Muhammad bin Maslamah (may Allah be pleased with him) said: When the Prophet (peace and blessings be upon him) passed judgement concerning Banu Qurayzah, the tribe of al-Aws was grieved by it, so the Messenger of Allah (peace and blessings be upon him) sent two captives to every household of al-Aws, and he also sent two captives to Banu Harithah.
