Do the children of a deceased person inherit from their grandfather who died as the sole son, and do the grandfather's brothers and the children of the grandfather's brother inherit?

If a man dies and leaves behind a wife, two daughters, children of a deceased son, and full brothers and their children, the inheritance is divided as follows: The wife receives one-eighth due to the existence of a direct descendant heir. The two daughters receive two-thirds. The remainder goes to the children of the deceased son (the grandchildren), with the male receiving the share of two females. The full brothers and their children receive nothing due to the presence of the grandchildren. It is preferable to present the matter to the Sharia court.
