The money of the person from whom

Q 1: A man borrowed from another man 400 Riyals. This man died without leaving behind heirs except a wife. The borrower gave the wife 100 Riyals only, and asks what should he do with the rest of the money?

A: If the situation is as the questioner has mentioned, he could pay the rest of the money to the judge in his district, and receive a receipt for this payment. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
