Hadith.5745 - In the narration of Al-Sakuni: " Imam Ali ibn Abi Talib عليه السلام used to grant inheritance to a Magian who married his mother, sister, or daughter from two aspects - one being that she was his mother, and the other that she was his wife."
I do not issue legal rulings based on what Al-Sakuni narrates alone.
If a Magian leaves his mother, who is also his sister and daughter, then the mother is entitled to one-sixth, the daughter receives one-half, and the remainder is distributed between them proportionally according to their shares. She does not inherit anything in the capacity of a sister because siblings do not inherit alongside the mother.
If he leaves his daughter, who is also his sister and wife, then she receives half of the inheritance as his daughter, and the remainder is returned to her. She does not inherit anything from the shares allocated to a sister or wife.
If he leaves his sister, who is also his wife, and a brother, the estate is divided between them, with the male receiving twice the share of the female. She does not inherit anything in the capacity of a wife. This principle applies across similar cases. If a Magian marries his daughter and fathers two daughters from her, and then he dies, he leaves behind three daughters, and the wealth is divided equally among them.
If one of the two daughters dies, she leaves behind her mother, who is also her paternal sister, and her other paternal sister. In this case, the wealth goes to the mother, who is also her paternal sister, because siblings do not inherit when parents are present.
If the daughter of the daughter dies after the father's death, she leaves behind her mother, who is also her paternal sister. The entire inheritance goes to the mother in her capacity as a mother, and she does not receive anything in the capacity of a sister.
If a Magian marries his daughter and she bears him a daughter, and then he marries the daughter of his daughter, and she bears him another daughter, and then he dies, the wealth is divided among them in thirds. If the first wife, whom he initially married, dies, the inheritance goes to her daughter. If the middle daughter dies after the father's death, then her mother, who is the eldest, is entitled to one-sixth of the inheritance, and her daughter, who is the youngest, receives half. The remainder is distributed between them in proportion to their respective shares.
If the deceased daughter is the youngest and the eldest remains, the entire inheritance goes to her mother, who is the middle daughter, while the eldest, being both a sister and a grandmother, does not inherit anything because siblings do not inherit alongside the mother.
If a Magian marries his daughter and she bears him two daughters, and then he marries one of them and she bears him a daughter, and then he dies, the inheritance is divided into four equal parts among them, and none of them inherits due to the marital relation.
If the daughter whom he married last dies, she leaves behind her daughter, her mother, and her sister, who is also her grandmother. The daughter receives half, the mother gets one-sixth, and the remainder is distributed between them in proportion to their shares, while the sister-grandmother receives nothing.
If a Magian marries his mother and she bears him a daughter, and then he marries the daughter and she bears him a son, and then he dies, the mother is entitled to one-sixth, and the remainder is divided between the son and daughter, with the male receiving twice the share of the female.
If his mother dies after him, the inheritance goes to her daughter, whom the Magian married, and the daughter's children do not inherit anything alongside their mother.
If the mother does not die, but the first daughter dies after the Magian, her mother, who is also the first daughter of the Magian, receives one-sixth of the inheritance.
If the son dies after the father while his mother and the Magian's mother are still alive, the entire inheritance goes to his mother, and the Magian's mother does not receive anything.
If a Magian marries his mother and she bears him a son and a daughter, and later his son also marries his grandmother (the Magian's mother) and she bears him a daughter, and then the Magian dies, his mother is entitled to one-sixth, and the remainder is divided between his son and daughter, with the male receiving twice the share of the female.
If his mother dies after him, the inheritance is divided between her son and daughter in the ratio of two shares for the male and one for the female.
If the mother does not die but the son dies after his father, his mother is entitled to one-sixth, and his daughter receives half, while the remainder is distributed between them proportionally according to their shares, and his sister does not inherit anything.
If a Magian marries his mother and she bears him a son and a daughter, and then he marries his sister and she bears him a son and a daughter, and later this son also marries his sister and she bears him a son and a daughter, and then the Magian dies, his mother is entitled to one-sixth, and the remainder is divided between his son and daughter, with the male receiving twice the share of the female.
If his son dies after him, his mother receives one-sixth, and the remainder is divided between his son and daughter with the same proportion.
If his grandson dies after him, his mother receives one-sixth, and the remainder is divided between his son and daughter with the male receiving twice the share of the female.
If the Magian's mother dies after all of them, the entire inheritance goes to her daughter, and the remaining relatives are excluded from inheriting.
