How is the estate of a man who died leaving behind a mother, a wife, four full brothers (sons), and a half-sister (daughter) distributed, given that one of his sons then died, followed by his mother (the paternal grandmother of the sons), and then his wife (the mother of the sons)? And how is the remaining estate distributed among the three full brothers and the half-sister?

If the deceased leaves behind a mother, a wife, four sons, and a daughter, the mother receives one-sixth, the wife receives one-eighth, and the remainder is divided among the sons and the daughter, with the male receiving the share of two females. If one of the sons dies and leaves a mother and full siblings, the mother receives one-sixth, and the remainder goes to the siblings. If the grandmother dies and her son's children are alive, her son's children inherit, with the male receiving the share of two females. However, if the mother dies and has children, and there is only a half-sister through the mother, her inheritance is divided only among her full-blood male and female children. Inheritance cases should be referred to the Sharia (definition) courts due to the possible existence of wills, debts, or other rights that may take precedence over the heirs' rights.
