Narrated Amr bin Shuaib: On his father's authority, said that his grandfather told that a A man came to the Prophet ﷺ crying for help. He said: His slave-girl, Messenger of Allah! He said: Woe to you, what happened with you ? He said that it was an evil one. He saw the slave-girl of his master; he became jealous of him, and cut off his penis. The Messenger of Allah ﷺ said: Bring the man to me. The man was called, but people could not get control over him. The Messenger of Allah ﷺ then said: Go away, you are free. He asked: Messenger of Allah! upon whom does my help lie? He replied: On every believer, or he said: On every Muslim. Abu Dawud said: The name of the man who was emancipated was Rawh bin Dinar Abu Dawud said: The man who cut off the penis was Zinba' Abu Dawud said: The Zinba' Abu Rawh was master of the slave.

Benefits and Issues: If an owner commits injustice against his slave and severs his limbs, then the slave will be set free. And there is a difference of opinion among the jurists regarding taking retribution (qisas) from the owner, as its brief detail has already been mentioned.

´'Amr bin Shu'aib narrated from his father that his grandfather said:` “A man came to the Prophet (ﷺ) screaming. The Messenger of Allah (ﷺ) said to him: 'What is the matter with you?' He said: 'My master saw me kissing a slave woman of his, so he cut off my penis.' The Prophet (ﷺ) said: 'Take me to the man.' He was sought but could not be found, so the Messenger of Allah (ﷺ) said: 'Go, for you are free.' He said: 'Who will protect me, O Messenger of Allah (ﷺ)? What if my master enslaves me again?' The Messenger of Allah (ﷺ) said: 'Your protection will be (incumbent upon) every believer or Muslim.'”

Benefits and Issues: ➊ If a person severs the limbs of his slave, retribution (qisas) will not be taken from the master.

➌ By "limbs" are meant the nose, ears, or hands and feet, etc.
