A man was given a gift by his father before his death, and he now wants to return it to the estate; what is required of him, given that he has benefited from it?

Question:
Honorable Shaykh, may Allah grant you success. A man was given a gift by his father before his death, and his father singled him out for it. Now that his father has passed away, this gift has remained with him for years, and he has benefited from its produce. He wants to return it to the estate. What is required of him regarding what has already passed?

Answer:
Faith. Regarding what has already passed: he returns it and returns the produce he obtained from it. He returns it along with the produce he gained from it. Yes, his liability is cleared by doing so.
