Brothers from a Mother with the Grandfather

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from ibn Sinan who has narrated the following: “I once asked abu ‘Abd Allah عليه السلام, about the case of a man who leaves behind his brother from his mother. He (the Imam) said, ‘If he has not left other heirs besides him the legacy belongs to him.’ I then asked about a brother from a mother with a grandfather. He (the Imam) said, ‘One-sixth must be given to the brother from his mother and the rest is given to the grandfather.’ I then asked about a brother from the father and a grandfather. He (the Imam) said, ‘The legacy between them is in equal shares.’”
