How is the inheritance divided among: two grandsons, four full brothers, and two daughters?

If the heirs are two daughters, two grandsons (sons of a son), and full brothers, then the two daughters receive two-thirds, and the remainder goes to the two grandsons. The full brothers inherit nothing, as they are excluded by the male lineal descendant. The estate is divided into six shares: each daughter receives two shares, and each grandson receives one share. It is advisable to refer the matter to the Sharia courts due to the possible existence of wills or debts of which the heirs may not be aware.
