Sayyiduna Abdullah bin Shaddad said: "The daughter of Hamzah (may Allah be pleased with him) freed a slave of hers in the time of the Messenger of Allah (peace and blessings be upon him), and he died and left behind a daughter of his, so the Prophet (peace and blessings be upon him) gave the daughter of Hamzah half and gave his daughter half."
