Narrated Al-Mughira bin Shu`ba: `Umar bin Al-Khattab asked (the people) about the Imlas of a woman, i.e., a woman who has an abortion because of having been beaten on her `Abdomen, saying, Who among you has heard anything about it from the Prophet? I said, I did.'' He said, What is that? I said, I heard the Prophet saying, Its Diya (blood money) is either a male or a female slave.' `Umar said, Do not leave till you present witness in support of your statement.
