How is the estate of a single young man who died leaving behind his mother, a full brother, a full sister, four paternal half-brothers, and four paternal half-sisters, distributed, given that his father had passed away?

The mother's share is one-sixth due to the presence of siblings. The remainder goes to the full brother and full sister by ta'sib (agnatic inheritance), with the male receiving the share of two females. The paternal siblings receive nothing as they are excluded by the full siblings. The inheritance is divided into 18 shares: the mother receives 3 shares, the full brother 10 shares, and the full sister 5 shares. The enquirer is advised to refer the matter to the Sharia courts if there are other heirs, bequests, or debts.
