It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the day of the Trench, the Prophet (peace and blessings be upon him) passed by a woman who had been killed and said: "Who killed her?" A man said: I did, O Messenger of Allah. He (peace and blessings be upon him) asked: "Why?" He said: She grappled with me over my sword. So he (peace and blessings be upon him) fell silent.
