What is incumbent upon a woman who traveled and returned on the same day, then combined and shortened the Dhuhr, Asr, Maghrib, and Isha prayers in her home after her return?

The woman must repent to Allah for her shortcomings in learning the rulings of the Sharia. She must make up the Dhuhr, Asr, and Isha prayers that she performed shortened, as it was obligatory for her to complete them. As for the Maghrib prayer, it is not shortened; if she performed it as three rak'ahs, then her duty has been fulfilled.
