How is the inheritance divided among: a father, a mother, two brothers by the father's side, a son of a brother by the father's side, three paternal uncles (full brothers of the father), four sisters by the father's side, and four sisters by the mother's side?

If the heirs are a father, a mother, and siblings, then only the father and mother inherit. The siblings are completely excluded by the father. The mother's share is reduced from one-third to one-sixth due to the presence of siblings.

The inheritance is divided as follows: The mother receives one-sixth (1/6), and the father receives the remainder (5/6) by both fixed share and residuary right. The common denominator for the problem is six.

Some scholars, like Ibn Taymiyyah, held the view that siblings who are excluded by the father do not cause the mother's share to be reduced from one-third to one-sixth; rather, she inherits the full one-third, and the father takes two-thirds by residuary right. However, the fatwa is based on the view of the majority of scholars.
