How is an inheritance calculated for heirs including: a father, a mother, a pregnant wife, two grandmothers, six full brothers, five full sisters, seven paternal half-brothers, six paternal half-sisters, a full paternal uncle, and nine sons of a full paternal uncle, with one son of a full paternal uncle having been missing for eight years?

From those mentioned, the mother, father, wife, and fetus alone inherit, while the rest are excluded. It is preferable to delay the division of the inheritance until the condition of the fetus becomes clear. If the heirs insist on immediate division, the father, mother, and wife should be given the minimum share due to them under all possible estimations for the fetus, and the most advantageous share should be reserved for the fetus, which is the inheritance of two females.

Thus, the mother receives one-sixth, the father one-sixth due to the presence of the fetus, and the wife one-eighth due to the presence of the fetus.

Two-thirds are reserved for the fetus, and the issue becomes 'a'ilah (one where the shares exceed the total).

If the inheritance is divided into 432 shares, the mother takes 64 shares, the father 64 shares, the wife 48 shares, and 256 shares are suspended for the fetus.

If the fetus is two females, they take all of the suspended shares. If it is stillborn, the suspended shares are divided among the mother, father, and wife. If it is male, he takes 234 shares from the suspended amount, and the remainder is divided among the mother, father, and wife. If it is female, she takes 216 shares from the suspended amount, and the remainder is divided among the mother, father, and wife. If it is one male and one female, they take 234 shares, and the remainder is divided among the mother, father, and wife. The same applies if the fetus turns out to be two males.
