How is the inheritance to be divided between a full brother, a full sister, and three paternal half-brothers, given the existence of missing relatives (a full brother and three paternal half-brothers) who died after the deceased and left children whose whereabouts are unknown, and with doubt as to whether the full sister died before or after the deceased?

If it is established that the missing person died after the owner of the estate, he has a share in the inheritance, and it is paid to his heirs. If he cannot be reached after searching, his share is given as charity on his behalf with a guarantee. As for the full sister, it must be verified whether she died before or after the owner of the estate. If this cannot be ascertained, she does not inherit. The inheritance is divided among the full brothers and full sisters, with the male receiving the share of two females. The paternal brothers receive nothing. Inheritance matters should be referred to the Sharia courts for precise investigation, as there might be wills, debts, or rights that take precedence over the heirs' rights.
