7. A number of our people have narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Husayn ibn SaTd from ‘Abd Allah ibn Bahr from Hariz from Zurarah who has narrated the following: “Abu ’Abd Allah (a.s.), once said to me, ’O Zurarah, what do you say about the case of a man who leaves behind his both parents and brothers from his mother’s side?’ He (the narrator) has said that he said, ‘One-sixth is for the mother and the rest is for the father.’ He (the Imam) asked, ’On what basis do you say so?’ I replied, ‘I have heard Allah, most Majestic, most Glorious, saying in His book, ’. . . if there are brothers then one-sixth is for his mother.’ (4:11) He (the Imam) said, ’Fie on you O Zurarah, they are brothers from the father’s side. If brothers are from the mother’s side, they do not bar the mother from receiving the one-third.’”

I found in it this, ’If a deceased leaves behind his daughter and mother, the share of the daughter is one- half or three shares and for the mother one-sixth. The legacy is made in four parts, of which three are for the daughter and one is for the mother/” “He (the narrator) has said, I read in it that, “If a deceased leaves behind his daughter and his father, the share of the daughter is one-half: three shares and the share of the father is one-sixth share. The legacy is made in four parts of which three are for the daughter and one is for the father.’” “Muhammad has said, T found in it that if a deceased leaves behind both parents and his daughter; the share of the daughter is one-half, three shares and the shares of parents are one-sixth for each. Such legacy can be made of five portions of which three are for the daughter and two for the parents.’”
