The son of Tawus narrates from his father: My father had a written document in which there were rulings regarding different types of blood money (diyah), which were conveyed to the Prophet Muhammad (peace be upon him) through revelation. Whatever decisions the Prophet Muhammad (peace be upon him) made regarding blood money and charity were all according to revelation. In that book, it was written regarding the Prophet Muhammad (peace be upon him): (He, peace be upon him, said:) "The blood money for accidental killing will be the blood money for unintentional killing, such as if someone is killed by a stone, stick, or staff, while the killer did not raise a weapon."
