Narrated Aishah, Ummul Muminin: The Messenger of Allah صلی اللہ علیہ وسلم Said: The blood of a Muslim man who testifies that there is no god but Allah and that Muhammad is Allah's Messenger should not lawfully be shed except only for one of three reasons: a man who committed fornication after marriage, in which case he should be stoned; one who goes forth to fight with Allah and His Messenger, in which case he should be killed or crucified or exiled from the land; or one who commits murder for which he is killed.
