Does the compulsory bequest apply to the children of a full brother who died before his brother (the inheritor) who had no offspring, given the existence of half-siblings to this deceased uncle?

"The obligatory will," which entails bequeathing to grandchildren the share of their parents, violates Islamic law because Allah Himself undertook the division of inheritance. Siblings' children do not inherit if siblings are present, and a full brother's son does not inherit from his paternal uncle, even in countries that apply "the obligatory will," which is restricted to grandchildren.
