How is the inheritance divided among the grandfather (father's father), 3 paternal half-brothers, 3 maternal half-brothers, the husband, the full sister, the paternal half-sister, and 2 maternal half-sisters?
Brothers and sisters from the mother's side are completely excluded from inheritance by the paternal grandfather, meaning they receive no share of the estate, by consensus. If the deceased left behind only a husband, a paternal grandfather, brothers and a sister from the father's side, and a full sister, the husband receives half due to the absence of any inheriting offspring.
According to the majority opinion that brothers inherit alongside the paternal grandfather, the brothers and sister from the father's side are calculated together with the full sister. They compete with the grandfather, who takes one-third of the remaining estate after the husband's share is deducted. What remains then goes to the full sister, and the brothers from the father's side and the sister from the father's side receive nothing. The estate is divided into six shares: the husband receives half (three shares), the grandfather receives one share, and the full sister receives two shares.
As for the opinion of those who hold that the paternal grandfather excludes the brothers (the view of Abu Bakr and Ibn Abbas), the husband receives half as a fixed share, and the grandfather receives the remaining half by 'asabah (residuary heir), with nothing going to any of the brothers, including the full sister.
