Is distributing the proceeds from the rent of an inherited house to the son and daughter only, with the male receiving the equivalent of the share of two females, prior to the division of the inheritance, valid and in accordance with Islamic law? And what is the correct legal division of inheritance?

If the deceased is the grandfather, the inheritance is divided as follows: The wife (grandmother) receives one-eighth due to the presence of a lineal descendant heir, and the remaining portion goes to the children (the maternal uncle and the mother), with the male receiving the share of two females. If the grandmother dies thereafter, her share from the grandfather's inheritance goes only to her children (the maternal uncle and the mother), and nothing goes to the grandmother's siblings due to the presence of a male lineal descendant heir of the deceased. The rent of the house is divided among the heirs according to each heir's share.
