Sayyiduna Shuraid bin Suwaid Thaqafi رضي الله عنه narrates: I said, "O Messenger of Allah! My mother made a will that we should free a slave on her behalf. I have a black slave-girl. Should I free her?" The Prophet صلى الله عليه وسلم said, "Call her." The slave-girl came, and the Prophet صلى الله عليه وسلم asked, "Who is your Lord?" She replied, "Allah, the Exalted." The Prophet صلى الله عليه وسلم asked, "Who am I?" She replied, "The Messenger of Allah." The Prophet صلى الله عليه وسلم said, "Free her."
