It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) with a black slave girl and said: "It is binding upon me to free a believing slave." So the Prophet (peace and blessings be upon him) asked the slave girl: "Who is your Lord?" She pointed towards the sky and said: "Allah." He (peace and blessings be upon him) asked: "And who am I?" She said: "The Messenger of Allah." And she gestured with her hand towards the ground. Then the Prophet (peace and blessings be upon him) said to the man: "Free her, for she is a believer."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Awn except al-Mas'udi."
