Do the brothers of the husband have a share in the inheritance if he dies and leaves a wife and four daughters, and he has no sons? And does the grandson inherit from his grandmother if his mother dies before his grandmother?

Firstly, if the deceased is survived by a wife, four daughters, and three brothers, the inheritance is divided as follows: the wife receives one-eighth due to the existence of a inheriting offspring, the daughters receive two-thirds, and the remaining portion goes to the brothers by ta'sib (residuary heirship) if they are full brothers or paternal half-brothers.

Secondly, in the aforementioned case, the daughter's son does not inherit anything from his grandmother because the daughter's son is not among the heirs by fard (fixed share) or ta'sib. Anyone who traces their lineage through a female does not inherit, with the exception of maternal half-brothers.
