What is the ruling on distributing the inheritance of a brother who passed away abroad and had a wife and two daughters who hold the nationality of the foreign country?

If the deceased left behind only a wife and two daughters, the wife gets one-eighth due to the presence of a lineal descendant, and the two daughters get two-thirds. The remainder is returned to them. Issues of inheritance must be brought before the Sharia courts for investigation, as there might be another heir, or bequests, or debts that take precedence over the rights of the heirs.
