How is the inheritance divided among the deceased's heirs: one full brother, two daughters, and one full sister?

If the deceased left no heirs other than his two daughters, a full brother, and a full sister, then the two daughters receive two-thirds (six shares out of nine), the full brother receives two shares, and the full sister receives one share. The matter must be referred to the Sharia courts to verify the existence of other heirs, bequests, or debts.
