A single full sister receives one-half, and two or more receive two-thirds. These shares are reduced only through proportional reduction. If they inherit alongside one or more full brothers, they have no prescribed share. Instead, they divide the estate among themselves if they are the only heirs, or whatever remains after the prescribed shares have been allotted to any other heirs, with each male receiving the share of two females.

In the absence of full siblings, paternal half-siblings inherit as full siblings do: males as males and females as females. The exception is the Shared Case, in which they do not share with the maternal half-siblings, since they do not share the same mother. Paternal half-siblings receive nothing alongside a full brother. Alongside one or two full sisters, they receive whatever remains of the estate, dividing it equally if they are all male, or with each male receiving the share of two females if they include both males and females. If they are all female, they receive nothing alongside two or more full sisters. Alongside one full sister, however, they receive a prescribed share of one-sixth, completing the two-thirds. Where full or paternal half-sisters are present alongside a daughter or daughters, the paternal half-sisters receive nothing alongside full sisters, even if there is only one full sister.

Chapter: The Inheritance of Maternal Half-Siblings

A single maternal half-sibling receives one-sixth. If there is more than one, they share one-third equally, whether male or female. There is no instance in the prescribed shares in which males and females receive equal shares except the inheritance of maternal half-siblings. They inherit only in a case of kalāla: where the deceased leaves no son or male-line grandson, however remote, and no father or paternal grandfather, however remote.

Chapter: The Inheritance of Siblings Alongside the Grandfather

Alongside full or paternal half-siblings, the grandfather is treated as a brother and shares the estate with them, with each male receiving the share of two females, unless one-third is more advantageous to him; in that case, his share is not reduced below one-third. If paternal half-siblings are present alongside full siblings, the full siblings count them against the grandfather, thereby preventing him from receiving a larger share. Whatever is allotted to the paternal half-siblings in this division is then transferred to the full siblings, and the paternal half-siblings receive nothing alongside them. The exception is where there is only one full sister and more than half the estate remains after the grandfather has received his share. In that case, whatever remains after the sister’s share goes to the paternal half-siblings, with each male receiving the share of two females. If, alongside
