Abdullah bin Shaddad (may Allah have mercy on him) said: The daughter of Sayyiduna Hamzah bin Abd al-Muttalib (may Allah be pleased with him) had a slave. The daughter of Sayyiduna Hamzah (may Allah be pleased with him) freed the slave, and then the slave died. He left a daughter and his former mistress who had freed him, the daughter of Sayyiduna Hamzah (may Allah be pleased with him). The dispute was brought to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) gave each of them half.
This is mursal; it has also been narrated mursal through other routes, some of which strengthen others.
