What is the distribution of inheritance for a man leaving behind his mother, his brother, and a slave woman pregnant by him (umm walad), who subsequently gives birth to twins: a son and a daughter, where only one cried out but the identity of the crier is unknown?

Primary text

If the son was the one crying out, the mother receives one-sixth (Suds), and the remainder is divided between the mother of the deceased son (who inherits one-third of the remainder) and the paternal uncle (uncle). This scenario yields a total denominator of 18: the deceased's mother receives 3 shares, the umm walad receives 5 shares, and the uncle receives 10 shares. If the daughter was the one crying out, the matter is calculated from a base of 6 shares: the mother receives one share, and the uncle receives two shares. These two calculations (18 and 6) are reconciled by multiplying to find a common denominator (18). The certain portion received by each heir is derived by summing their fractional share from the 18-part calculation (multiplied by 1) and their share from the 6-part calculation (multiplied by 3). The mother's one-sixth share remains unchanged. The uncle receives 10 shares from the first calculation and 12 from the second (4*3), totaling 22 shares. The umm walad receives 5 shares from the first calculation and 3 from the second (1*3), totaling 8 shares. The remainder of 2 shares between the brother and the umm walad is suspended until settlement.
