It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he mentioned a narration similar to the previous one, and in it he said: The Messenger of Allah (peace and blessings be upon him) ruled that a ghurrah (a male or female slave) be given for her fetus, and that she (the killer) be killed for her. (Ibn Jurayj said:) I said to Amr bin Dinar: "Ibn Tawus informed me from his father that he (peace and blessings be upon him) ruled for her diyah (blood money) and a ghurrah for her fetus." He said: "You have made me doubt."
