How is inheritance divided among: one full brother, one maternal half-brother, one daughter, and one wife?

If the deceased leaves behind only a wife, a daughter, a full brother, and a maternal brother, then the wife receives one-eighth due to the presence of a lineal descendant. The daughter receives one-half since she is the sole daughter. The remaining portion goes to the full brother by ta'sib (residuary heirship). The maternal brother receives nothing because he is completely excluded by the daughter. The inheritance is divided into eight shares: one share for the wife, four shares for the daughter, and three shares for the full brother. The enquirer is advised to refer the matter to the Sharia courts for investigation and to confirm the absence of other heirs, debts, or bequests.
