1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhassin ibn Ahmad from Aban ibn ‘Uthman from ’Isma‘il al-Ju‘fiy who has narrated the following: “About the case of a woman who leaves behind her husband and parents, abu Ja‘far , has said, ‘The share of the husband is one-half, the share of mother is one-third and the remaining belongs to the father.’ About the case of a man who leaves behind a wife and both parents, he (the Imam) said, ‘The share of the wife is one-fourth, the share of the mother is one-third and the remaining belongs to the father.’”
