How is the inheritance divided among four full brothers, seven sons of a full brother, four daughters, and two full sisters?

The heirs are only the daughters and full brothers; the sons of the full brother receive nothing as they are excluded by the full brothers.

The inheritance is divided as follows: The daughters receive two-thirds as a prescribed share, based on the Almighty's saying: "But if there are [only] daughters, two or more, for them is two thirds of what he left." The remaining one-third goes to the full brothers and sisters by way of ta'sib (residuary heirship), with the male receiving twice the share of the female, based on the Almighty's saying: "And if there are brothers and sisters, then for the male will be the share of two females."

It is advisable to refer inheritance matters to the Sharia courts for investigation and to ensure there are no other heirs, wills, or debts that take precedence over the rights of the heirs.
