Q: If a woman takes an oath that “If I do this or do not do this, I will become a Kafir forever”. If she breaks the oath will she become a Kafir forever?
A: No. But it is very very dangerous to make these types of statements. Ask Allah’s forgiveness and don’t repeat these things in the future.
And Allah Ta’ala (الله تعالى) knows best.
