It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him and his family) said: The blood money (diyah) for accidental killing resembling intentional murder (shibh al-‘amd) is as severe as that for intentional murder (‘amd), however, in shibh al-‘amd the killer cannot be killed (in retaliation). This occurs when Satan incites discord among people. Abu Nazr says: Then, in blind fighting, things like sticks, whips, and stones are thrown, while there is neither any sedition nor weapons involved.
