He died leaving behind a half-brother from his father's side, a full nephew, and a wife.

If the deceased leaves behind only a wife, a paternal half-brother, and a full-brother's son, and has no inheriting lineal descendants or ascendants (father, paternal grandfather, mother, maternal grandmother), then the wife receives one-fourth as a fixed share, based on the Almighty's saying: "And for them [wives] is one fourth of what you leave if you have no child." (An-Nisa: 12). The remainder goes to the paternal half-brother by way of residuary inheritance (asabah), based on the Prophet's (peace be upon him) saying: "Give the prescribed shares to those who are entitled to them; and whatever remains is for the closest male relative." The full-brother's son receives nothing.

The estate is divided into four shares: one share for the wife (one-fourth), and three shares for the paternal half-brother (the remainder).

It must be emphasized that inheritance matters are serious and complex. They cannot be adequately resolved by a mere fatwa. Rather, they should be referred to Sharia courts or discussed directly with scholars, to ensure that there are no other heirs, wills, debts, or other rights that take precedence over the heirs' entitlement.
