Types of Blood-Wit (Kitab Al-Diyat)
Dawud :: Book 39 : Hadith 4504
Narrated Abdullah ibn Amr ibn al-'As:
A man came to the Prophet (peace_be_upon_him) crying for help. He said: His slave-girl, Apostle 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 Apostle of Allah (peace_be_upon_him) said: Bring the man to me. The man was called, but people could not get control over him. The Apostle of Allah (peace_be_upon_him) then said: Go away, you are free. He asked: Apostle of Allah! upon whom does my help lie? He replied: On every believer, or he said: On every Muslim.
