A man came crying out to the Prophet ﷺ, and the Messenger of Allah ﷺ asked him, "What is the matter with you?"He replied, "My master saw me kissing a slave-girl of his, so he cut off my private parts."The Prophet ﷺ said, "Bring the man to me." The man was sought but could not be found.The Messenger of Allah ﷺ then said, "Go, you are free."He asked, "Messenger of Allah, upon whom does my support fall?" meaning, what if my master tries to enslave me again?The Messenger of Allah ﷺ replied, "Upon every believer," or "every Muslim."
