What is the ruling on prayers missed before knowing the correct method of ghusl after menstruation, and is ghusl required again if one performed ghusl with the previous method and then learned the correct method on the same day?

There are two descriptions for ghusl (definition): sufficiency and perfection. If the previous ghusl included the pillars of ghusl, with water reaching the entire body, then the state of ritual impurity is lifted, and there is no need to repeat it. If water did not reach some parts of the body, then only the unwashed limb must be washed, without repeating the entire ghusl, because continuity (muwalat) is not a condition for the validity of ghusl according to the majority of scholars. If the previous ghusls were insufficient, then the prayers that followed them are invalid and must be made up according to the majority of scholars. Some scholars, however, are of the view that there is no need to make up the prayers due to ignorance of the ruling.
