Is expiation obligatory, along with making up the missed Ramadan fasts, for the wife whose health condition prevented her from making them up before the onset of the following Ramadan?

If the wife was able to make up her fasting days before the next Ramadan began, she must hasten to do so. If she delayed, despite being able to, until the next Ramadan began, then she must make up the days along with a fidyah (expiation) of feeding one poor person for each day. However, if her excuse persisted and she was unable to make up the days until the next Ramadan began, then she only has to make up the days without a fidyah, because she is excused for the delay.
