The ruling on a woman saying to her husband, "You are forbidden to me"

Question:
The Shaykh explained whether the act of intercourse with her husband is taken into account, such that she says to her husband, "You are forbidden to me," or not?

Answer:
This is a point of disagreement among the scholars. If a woman says to her husband, "You are to me like the back of my father" or "like the back of my brother," some scholars heard that this has no ruling, because zihar is specific to men and nothing follows from it. Others say this is zihar, just like a man's zihar, and she owes an expiation like a man's: freeing a slave. If she cannot find one, she fasts two consecutive months. If she cannot do that, she feeds twenty poor people, based on the generality of the verse.
The third opinion, which is the correct one, is that this is considered an oath. It is an oath that carries an expiation for an oath: freeing a slave, or feeding ten poor people, or clothing them. If she cannot do that, she fasts three days. This is the expiation for an oath, and it is the best. Yes.
