Musannaf Ibn Abi Shaybah

Hazrat Sha’bi narrates that Hazrat Ali (may Allah be pleased with him) used to say: In the case of unintentional killing, the blood money (diyah) for a woman is half of that for a man in those limbs which are completely broken and entirely lost. And Hazrat Ibn Mas’ud used to say: In the case of unintentional killing, the blood money for a woman will be half of that for a man, except in the case of teeth and deep wounds; for these two, the blood money will be equal. And Hazrat Zaid bin Thabit used to say: In the case of unintentional killing, the blood money for a woman will be like that for a man until it reaches one third of the diyah; then, for any wound greater than this, it will be half the diyah.
