The ruling on taking zakah to pay off a debt and spending it on non-essential items

Question : A questioner says: A man had a debt, so he took zakah from his wife to pay it off. However, he put it in his pocket and then spent it on himself and his wife for non-essential things. This happened last year. Is the zakah from his wife valid in this case? If not, what is obligatory for him now?

Answer : As for the zakah, it is valid because it was placed in its proper place. As for the husband’s action, it is a mistake, because a person should not enjoy completeness while he has a debt.
