Ubayd bin Umayr (may Allah have mercy on him) says that a man hosted some people from Hudhayl. A slave girl of theirs went to gather firewood, and one of their men tried to seduce her. She struck him with a stone and killed him. The matter was brought to Sayyiduna Umar (may Allah be pleased with him), and he said: "That one was slain by Allah; by Allah, blood money will never be paid for him."
