It is narrated from Abdullah bin Shaddad bin al-Had, the son of the daughter of Hamzah (may Allah be pleased with him), that "she (bint Hamzah) freed a slave of hers, and he died and left behind his daughter and his manumitter, bint Hamzah; so his daughter inherited half from him, and bint Hamzah half."
