Who has the right to keep the inheritance money of the minor children: the mother or the paternal grandfather?

Answer

The guardian of the minor children is their paternal grandfather whose responsibility it is to hold their shares in trust. It is not the right of the mother. According to the Shariah, the grandfather is the rightful guardian. However, if the grandfather is incapable or dishonest, then the inheritance of the minors should not be entrusted to him.
