Mishkat al-Masabih 3955

Rabah b. ar-Rabi’ said: When we were with God’s Messenger on an expedition he saw some people collected together over something and sent a man whom he told to see what these people were collected around. When he came and told him they were round a woman who had been killed he said, “This is not one with whom fighting should have taken place.” Khalid b. al-Walid was in charge of the van, so he sent a man to tell him not to kill a woman or a hired servant.
Abu Dawud transmitted it.
