How is the inheritance distributed among four daughters, a wife, a mother, and eight siblings (three full brothers and five half-sisters from the father's side)? And how can the inheritor ensure that the inheritance goes only to his daughters, wife, and mother?

Among the conditions for inheritance are the actual or constructive death of the testator. Siblings are not excluded from inheritance except in the presence of the father, grandfather, son, or grandson, or if the prescribed shares exhaust the entire estate. In the case where paternal half-siblings exist alongside full siblings, the paternal half-siblings are excluded. The estate is divided as follows: two-thirds for the daughters, one-eighth for the wife, and one-sixth for the mother. The remainder goes to the siblings by way of ta'sib (residuary inheritance), with the male receiving the share of two females, or equally if they are all males. It is not permissible to use deception to deprive an heir of their right. It is advisable to refer matters of inheritance to the Sharia (definition) courts to verify the existence of other heirs, wills, or debts, as these take precedence over the heirs' right to the property.
