It was narrated that 'Amr bin Ghalib said:
"Aishah said: 'Do you not know that the Messenger of Allah [SAW] said: It is not permissible to shed the blood of a Muslim, except a man who committed adultery after being married, or one who reverted to Kufr after becoming Muslim, or a life for a life.'" (JA)
