1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa and a number of our people have narrated from Sahl ibn Ziyad all from ibn Mahbub from abu Ayyub al-Khazzaz and others from Muhammad ibn Muslim who has narrated the following: “Abu Ja‘far عليه السلام, has said, ‘With the existence of a mother or father or son or daughter no one else inherits except the husband and wife. The one-half share of the husband is not reduced if there are no children; and from one-fourth of a wife nothing is reduced if there are no children; but if there is a child with them then one-fourth is the share of a husband and one-eighth is the share of a wife.’”
