How is the inheritance divided between one wife, one full sister, and six full nephews?

The wife takes one-fourth due to the absence of a direct descendant, and the full sister takes one-half. The remainder goes to the full brother's sons by 'asabah (agnatic kinship), with the male receiving the share of two females. The inheritance is divided into twenty-four shares: the wife receives one-fourth (six shares), the full sister receives one-half (twelve shares), and each son of the brother receives one share. The matter must be referred to the Sharia courts to investigate the heirs, bequests, and debts.
