Vow Not to Benefit from Brother's Property

I know someone who ruined his brother's tie, and therefore his brother got angry and said he vowed not to use any of his belongings. Later, he asked his brother, and he claimed that he didn't really intend to vow or meant only the tie. What is the ruling, and what should the brother do?

Hello 

If the brother did not intend to vow, there is no prohibition here.
