Deeming unlawful what is lawful as entailing making Kaffarah for an oath

Q 1: a person may give another something and say, "You have to take it, as I make it unlawful for me just like my mother." This habit is widespread in our country. What is the ruling on saying so?

A: If a person makes something lawful to him, other than his wife, unlawful for him, it does not become unlawful. However, he still has to make Kaffarah (expiation) for breaking an oath. It is related by Al-Bukhari on the authority of Ibn `Abbas (may Allah be pleased with them both) that he used to say, "Declaring something (other than the wife) as unlawful is similar to breaking an oath that must be expiated." (Part No. 23; Page No. 18) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
