How is the inheritance divided among: a wife, three daughters, a full brother, a full sister, and a full brother's son?

If the deceased left behind only a wife, daughters, full siblings (a full brother and a full sister), and a full brother's son, then:

The wife receives one-eighth (1/8) due to the presence of a lineal descendant. The daughters receive two-thirds (2/3) if they are more than two. The remainder is divided between the full brother and full sister by ta’sib (residuary inheritance), with the male receiving the share of two females. The full brother's son does not inherit because he is completely excluded by the full brother.

The estate is divided into 72 shares:

The wife receives 9 shares. The daughters receive 48 shares (16 shares for each). The full brother receives 10 shares. The full sister receives 5 shares.

Inheritance cases should be referred to Sharia courts for investigation.
