the sixth, [which is] the father's mother with her son, while her son is alive. Al-Tirmidhi extracted it (4). Sa‘id ibn Mansur also narrated it (5), except his wording is: "The first grandmother to whom the sixth was given is the father's mother with her son." Ibn Sirin said: "The first grandmother to whom the Messenger of Allah (may Allah bless him and grant him peace) gave the sixth (6) was the father's mother with her son (7)." This is because grandmothers are mothers who inherit the inheritance of the mother, not the inheritance of the father, so they are not screened [mahjub] by him, just like the mother's mothers.

Issues concerning this: [If there is] a father's mother and a father, she has the sixth and the remainder is his. According to the other position, the entirety is for him to the exclusion of her. [If there is] a mother's mother, a father's mother, and a father, the sixth is [divided] between them according to the first position. According to the second [position], the sixth is for the mother's mother, and the remainder is for the father. It has been said: The mother's mother has half the sixth, and the remainder is for the father; because if the father were nonexistent, the mother's mother would only have half the sixth, so she should not have more with his existence than she would have with his non-existence. The first [position] is more correct; because brothers, alongside the parents, screen the mother from half of her inheritance, but they do not take what they have screened her from; rather, it accrues to the father, and it is the same here. [If there are] three grandmothers on the same level and a father, the sixth is [divided] between them according to the first position, and [the whole sixth is] for the mother's mother according to the second position, and according to the third [position], the mother's mother gets one-third of the sixth, and the remainder is for the father. If there is a grandfather (8) alongside those on the same level, he does not screen anyone except his own mother. [If there is] a father, a father's mother, and a mother's mother's mother, according to the position of al-Khiraqi, the sixth is for the father's mother. Those who screened the grandmother by her son excluded the father's mother. Then those who hold that position differed; it was said: The entire sixth is for the mother's mother's mother, because the one who would screen her or compete with her has had her ruling dropped, so she has become like the non-existent. It was said: Rather, she has half the sixth according to the position of Zayd; because he allows the distant [grandmother] from the mother's side to inherit alongside the near [grandmother] from the father's side, so she would have half the sixth. It was also said: She has nothing; because she was screened by the father's mother, then the father's mother was screened by the father, so the entire wealth becomes for the father.
