Abu Hurayrah (may Allah be pleased with him) says that the Prophet (peace and blessings be upon him) ruled "a male slave or a female slave" concerning the fetus of a woman of Banu Lihyan. Then the woman died, so he (peace and blessings be upon him) assigned her inheritance to her son and husband, and placed her blood money upon her paternal kin ('asabah).
In the narration of Ibn Bukayr it says she was a woman of Banu Kinanah; and in the narration of al-Tayalisi it says that a woman of Banu Lihyan struck another and caused her to miscarry, so he (peace and blessings be upon him) ruled "a male slave or a female slave" for it. Then that woman died, so he (peace and blessings be upon him) gave her inheritance to her son and husband and placed the blood money upon her paternal kin.
