What is the share of each of the heirs (a sister, three brothers, a mother) in the estate of their deceased unmarried brother, given that the mother died after her son?

It is necessary to refer to the Sharia court or the competent authorities to inventory the inheritance, heirs, debts, and bequests before distribution.

If the heirs are limited to: a mother, two full brothers, one full sister, and one uterine brother, the inheritance is divided as follows: - The mother gets one-sixth due to the presence of siblings. - The uterine brother gets one-sixth. - The remainder goes to the full siblings, with the male receiving the share of two females.

The issue would consist of thirty shares: the mother gets five shares, the uterine brother gets five shares, the full sister gets four shares, and each full brother gets eight shares.

Then, the mother's share is divided among her living heirs at the time of her death, according to their prescribed legal shares.
