How is the sum of 4000 Sudanese Pounds, representing end-of-service entitlements (cash in lieu, furniture transport, and gratuity), distributed for a deceased person who did not have children, and whose heirs are: a father, a mother, 4 full brothers, 2 full sisters, and 2 sons of a full brother, knowing that his wife, whom he died three months after marrying, and his parents are still alive?

All sums disbursed by the company for end-of-service benefits enter into the deceased's estate and are divided among the heirs according to Islamic law. If the deceased leaves behind a wife, a father, a mother, and a group of siblings, and no other heirs, then the wife receives one-fourth, the mother one-sixth, and the remainder goes to the father by ta'sib (residuary heirship). The brothers, sisters, and nephews receive nothing because they are excluded by the father. The estate is divided into twelve shares: two shares for the mother, three shares for the wife, and seven shares for the father.
