Only three(1) grandmothers are eligible to inherit: the mother’s mother, the father’s mother, and the paternal grandfather’s mother, however high the line of motherhood may rise. In every case the nearer grandmother excludes the more remote. A grandmother who combines two lines of kinship receives two-thirds of the one-sixth.
Section
A lone daughter is allotted one-half; the same applies, in order, to a lone granddaughter through a son, to a lone full sister, and to a lone paternal sister. Two or more in any of these categories share two-thirds. If a male of the same degree renders them ʿaṣaba, the male receives the portion of two females.
One or more granddaughters through a son who have not been made ʿaṣaba are given one-sixth(3) alongside a single daughter; the same rule governs a great-granddaughter together with a nearer granddaughter, and a paternal sister together with a full sister.
A granddaughter through a son who has not become ʿaṣaba is excluded when there are two or more daughters; likewise a great-granddaughter in the presence of a daughter and a granddaughter, and a paternal sister in the presence of two full sisters.
The son’s daughters are rendered ʿaṣaba by a male descendant who is one degree below them whenever they need him. A full or paternal sister, when accompanied by a daughter or a granddaughter, becomes an agnatic residuary and takes what remains after the fixed shares.
A single maternal sibling, male or female, is entitled to one-sixth, while two or more maternal siblings share one-third equally.
