Hazrat Ata bin Yasar (may Allah have mercy on him) narrates that Hazrat Muawiyah bin Al-Hakam Al-Sulami (may Allah be pleased with him) said: I had a slave girl who used to graze my sheep at the place of Uhud and Jawaniyah. One day I went to her and suddenly a wolf took away one of the sheep from the flock. He (may Allah be pleased with him) said: I am a man from among the sons of Adam, I felt regret as they feel regret. But I slapped her face hard. Then I presented myself before the Messenger of Allah (peace and blessings be upon him), and I felt very bad about it. I said: O Messenger of Allah (peace and blessings be upon him)! Should I free her? The Prophet (peace and blessings be upon him) said: Bring her to me. Then the Prophet (peace and blessings be upon him) asked her: Where is Allah? She said: In the sky. The Prophet (peace and blessings be upon him) asked: Who am I? She said: You are the Messenger of Allah. The Prophet (peace and blessings be upon him) said: Free her, for indeed she is a believer.
