What is the share of each heir from (the mother, the daughter, the paternal grandfather (father of the father))?

If the deceased left behind only a mother, a daughter, and a grandfather, then the mother receives one-sixth, the daughter one-half, and the grandfather one-sixth plus the remainder by way of residuary right (ta'sib). Thus, the inheritance is divided into six shares: one share for the mother, three shares for the daughter, and two shares for the grandfather.
