Musannaf Ibn Abi Shaybah 39667 — The Battle of Khaybar

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the day of Khaybar a man took a woman captive and seated her behind him. The woman struggled with the man over the hilt of his sword, so the man killed the woman. Then the Messenger of Allah (peace and blessings be upon him) saw this woman (slain) and said: "Who killed this woman?" The people told him (peace and blessings be upon him), and he (peace and blessings be upon him) forbade the killing of women.
