Mishkat al-Masabih #3338

Ta’us, on the authority of Ibn ‘Abbas, reported God’s Messenger as saying, “If anyone is killed in error when people are throwing stones, or by beating with whips, or striking with a stick, it is accidental and the compensation for accidental death is due.* But if anyone kills someone deliberately retaliation is due, and if anyone tries to prevent it God’s curse and anger will rest on him, and neither supererogatory nor obligatory acts will be accepted from him.” Abu Dawud and Nasa’i transmitted it. *These are instances in which the actual person who killed him is not clearly known, or where there was no intention to kill.
