Narrated 'Amr b. Suh'aib: On his father's authority, said that his grandfather reported the Prophet (ﷺ) said: Blood-wit for what resembles intentional murder is to be made as severe as that for intentional murder, but the culprit is not to be killed. Khalid gave us some additional information on the authority of Ibn Rashid: That (unintentional murder which resembles intentional murder) means that Satan jumps among the people and then the blood is shed blindly without any malice and weapon.
