Ruling 2749

If the only heirs of the deceased are his father and his mother, the estate is divided into three parts: two parts are inherited by his father and one part by his mother. However, if the deceased has two brothers or four sisters, or one brother and two sisters, and they are all Muslims and free [i.e. not slaves], and their father is also the father of the deceased even though their mothers may be different, and they have been born, then they do not inherit anything while the deceased’s father and mother are alive. In such a case, his mother inherits one-sixth of the estate and his father inherits the rest.
