If a woman becomes pure from her menstrual period before the Maghrib prayer, does she pray only Asr, or does she combine Dhuhr with it?

If a woman becomes pure from menstruation or postpartum bleeding before sunset, with enough time remaining to pray Dhuhr and one rak'ah of 'Asr, both prayers (Dhuhr, then 'Asr) become obligatory for her. However, if the remaining time is only sufficient for four rak'ahs for a resident (or two rak'ahs for a traveler), then Dhuhr is dropped, and she is only obligated to pray 'Asr, because the limited time is specifically for the last prayer of the two prayers that share a time slot. And if she does not become pure until after sunset, or at a time insufficient for even one rak'ah, 'Asr is also dropped for her.
