The completion of the waiting period of the divorced woman in twenty-eight days

Question : A divorced woman. When twenty-eight days had passed for her, she came and said that her waiting period had ended.

Answer : We do not accept her claim, nor do we ever listen to her assertion. Why? Because this is impossible, given that we have established the minimum duration of menstruation as one day and one night, and the minimum duration of purity as thirteen days. Therefore, the waiting period cannot end in twenty-eight days. We do not accept her statement at all, even if she were among the most truthful of women.
