Is the distribution of the estate of a deceased, unmarried sister—whose father died before her—whereby her estate was divided among her brothers and sisters (three daughters and three sons), with the male receiving the share of two females, considered legally valid, given that one of the sisters in charge of distributing the inheritance believes that the inheritance verse in Surat An-Nisa (verse 12) stipulates that only one-third of the inheritance of a "kalalah" is to be distributed?

If you are full siblings or paternal half-siblings of the deceased, the aforementioned division is correct. However, if you are only maternal half-siblings, this is a matter of "kalalah" (one who dies without a father or child).

- Full siblings or paternal half-siblings of the deceased inherit, with the male receiving the share of two females.

- If the deceased has no father or child, and leaves behind only maternal half-siblings: if there is one maternal half-sibling, he receives one-sixth; if there are more than one, they share one-third equally between male and female.

- In the case that you are only maternal half-siblings, you receive one-third of the inheritance equally, and the remainder is returned to you if there is no other heir.
