How is the inheritance divided if the deceased left a mother, one wife, three daughters, and one full brother?

If the deceased leaves behind only a mother, a wife, three daughters, and a full brother, the inheritance is distributed as follows:

The mother receives one-sixth (1/6) due to the presence of a lineal descendant. The wife receives one-eighth (1/8) due to the presence of a lineal descendant. The daughters receive two-thirds (2/3) because they are more than two. The remainder goes to the full brother by way of ta’sib (residuary inheritance).

The inheritance is divided into 72 shares: 12 shares for the mother, 9 shares for the wife, 48 shares for the daughters (16 shares for each), and 3 shares for the full brother.
