How does one perform the Maghrib and Isha prayers in combination if their time began while one was traveling, and then menstruation occurred?

If a traveling woman delays the 'Isha prayer to combine it with the Maghrib prayer as a delayed combination, and then menstruates before praying them, she must make them up after purification according to the Shafi'is and Hanbalis. They shorten the prayers when making them up if she is still traveling, and likewise in residence according to the Hanafis and Malikis. However, according to the Hanafis and Malikis, she is not required to make them up.
