How is the monthly salary of a man who died leaving behind his parents, his wife, and his two children (a male and a female) to be divided, and do his brothers and sisters have a share in his inheritance, knowing that the number of brothers and sisters is unknown?

The salary disbursed to the deceased's family by his employer falls into three categories: First, it could be a gift designated by the granting entity, in which case it is not part of the inheritance. Second, it could be a right of the deceased, deducted from his salary, in which case it is part of the estate and is divided among the heirs. Third, it could be a mixture of both a gift and a deduction. As for the division of inheritance: the wife receives one-eighth, the parents each receive one-sixth, and the remainder goes to the son and daughter, with the male receiving the share of two females. The siblings are completely excluded from inheritance by the presence of a son and a father.
