It is narrated from Hazrat Shuraid (may Allah be pleased with him) that his mother advised him to free a Muslim slave on her behalf. He asked the Prophet (peace and blessings be upon him) about this, saying that he had a slave woman from the Nubia region of Abyssinia; could he free her? The Prophet (peace and blessings be upon him) said, "Bring her to me." I called her, and she came. The Prophet (peace and blessings be upon him) asked her, "Who is your Lord?" She replied, "Allah." The Prophet (peace and blessings be upon him) asked, "Who am I?" She replied, "You are the Messenger of Allah." The Prophet (peace and blessings be upon him) said, "Free her, for she is a Muslim."
