What is the ruling regarding the inheritance of a married man who died childless, and has one surviving full brother, in addition to half-brothers from the father's side, and his wife is still alive? Does the full brother inherit by ta'sib (residuary heirship) (3/4) and the wife by fard (fixed share) (one-fourth), while the half-brothers and the sons of deceased full brothers are disinherited?

If the heirs are limited to a wife, a full brother, paternal half-brothers, and nephews (sons of brothers), then the wife receives one-fourth due to the absence of children. This is supported by the Almighty’s saying: "And for them (wives) is one fourth of what you leave if you have no child." The remainder is given to the full brother, based on the Prophet’s (peace be upon him) saying: "Give the prescribed shares to their rightful recipients, and whatever remains is for the nearest male relative." The full brother has precedence over paternal half-brothers and nephews.

It is obligatory to refer inheritance matters to the Sharia courts for investigation, and to determine the heirs, debts, and bequests before distribution.
