2. Al-Husayn ibn Sa‘id has narrated from al-Nadr ibn Suwayd from al-Qasim ibn Muhammad ibn Sulayman who has narrated the following: “I once asked abu ‘Abd Allah عليه السلام, about the case of a man who has killed his mother; if he can inherit her. He (the Imam) said, ‘I heard my father عليه السلام, saying, “Whoever of the relatives kills one of his relatives he cannot inherit from that relative.’””
