What is the share of each heir from the inheritance if the deceased left behind a father, a full brother, a mother, and three full sisters?

If the deceased leaves behind only their mother, father, and siblings, then the mother receives one-sixth due to the presence of siblings, based on the Almighty's saying: "But if he has brothers [and sisters], the mother will have one-sixth." The remainder goes to the father by ta’sib (residuary heir), based on the Prophet's (peace be upon him) saying: "Give the prescribed shares to those who are entitled to them, and what remains is for the closest male heir." The siblings do not inherit because they are blocked by the father by scholarly consensus. Thus, the inheritance is divided into six shares: one share for the mother and five shares for the father. It is worth noting that some scholars hold the view that siblings blocked by the father do not reduce the mother's share from one-third to one-sixth, but the authoritative view is that of the majority. Finally, inheritance matters must be referred to the Sharia courts to verify all heirs, wills, and debts before distribution.
