Mention in Sefer Hasidim An anecdote is reported in Sefer Hasidim about Saadia ben Yosef "the sage," in which he ends a dispute between a servant who claims to be the heir of his deceased master and the man's true son and heir by having them both draw blood into separate vessels. He then took a bone from the deceased man and placed it into each of the cups. The bone in the cup of the true heir absorbed the blood, while the servant's blood was not absorbed in the bone. Using this as genetic proof of the son's true inheritance, Saadia had the servant return the man's property to his son.
