What are the prayers that must be made up upon purification from menstruation at night, given that the white discharge is not seen and one waits a day to ensure the cessation of blood?

If a menstruating woman becomes pure after the time for Ishā or Asr prayer has begun, she is obligated to pray the two combined prayers (Maghrib and Ishā, or Dhuhr and Asr). This is the view of the majority of scholars. However, if she becomes pure after Fajr, Dhuhr, or Maghrib, she is only required to pray one prayer, which is the prayer for which she became pure during its time, because these prayers are not combined. The sign of purity is either seeing the white discharge or complete dryness. The sign of dryness must be observed if the white discharge does not appear.
