Bukayr bin al-Ashajj (may Allah have mercy on him) said that the Sunnah is: "The free, whether man or woman, are equal in blood. If a woman's eye is gouged out, then in return that man's eye will also be gouged out." And it has also reached me from Zayd bin Thabit (may Allah be pleased with him) that "a man will be killed for a woman, and retaliation will be taken from him."
