Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that a slave came down from the fortress of Ta'if, and then his master came and said: O Messenger of Allah, have my slave returned to me. He (peace and blessings be upon him) said: "If a slave accepts Islam before his master, he is not returned to him; and if the master accepts Islam and then the slave accepts Islam, he is handed back to him."
