Was it correct for the wife to stop praying after seeing signs of menstruation on the first day, and its cessation on the following days until the seventh day?

The minimum duration for menstruation is one day and one night. If the signs observed by the wife (yellowish discharge, brownish discharge, or menstrual blood) reached a full day and night, then it is considered menstruation, and she must perform ghusl (ritual bath) and pray. However, if the duration of these signs was less than one day and one night, it is not considered menstruation, and she must pray. The wife erred by abandoning her prayers, and she must perform ghusl if what she saw was menstruation, seek forgiveness, and make up all the prayers she missed.
