What is the share of each heir from the inheritance if a man dies and leaves behind: one wife, one full paternal uncle, and also a nephew and niece from a full sister who passed away before him?

The deceased's wife receives one-quarter as a prescribed share due to the absence of a child, based on the Almighty's saying: "And for them is one fourth of what you leave if you have no child." The remainder goes to the full paternal cousin, based on the Prophet's (peace be upon him) saying: "Give the prescribed shares to those entitled to them; then whatever remains is for the closest male." The sister's son and daughter inherit nothing because they are from the kin by blood (dhawu al-arham), and dhawu al-arham do not inherit when there are 'asabah (agnatic heirs).
