I asked Abu Abdullah (as) about a man who spies on a group of people to look at their private matters, and they strike him, killing him, injuring him, or gouging out his eye. Imam (as) said: "There is no blood money (diyyah) for him. The Messenger of Allah (swt) (peace be upon him and his family) once had a man peep into his room through a crack, so the Messenger of Allah (swt) (peace be upon him and his family) approached him with an arrowhead to gouge out his eye, but he found that the man had left. The Prophet (peace be upon him and his family) then called out to him, saying: 'O' wicked one! Had you remained there, I would have gouged out your eye with it.'"
