A menstruating woman is obliged to make up missed fasts but not prayers
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ يَزِيدَ، قَالَ سَمِعْتُ مُعَاذَةَ، أَنَّهَا سَأَلَتْ عَائِشَةَ أَتَقْضِي الْحَائِضُ الصَّلاَةَ فَقَالَتْ عَائِشَةُ أَحَرُورِيَّةٌ أَنْتِ قَدْ كُنَّ نِسَاءُ رَسُولِ اللَّهِ صلى الله عليه وسلم يَحِضْنَ أَفَأَمَرَهُنَّ أَنْ يَجْزِينَ قَالَ مُحَمَّدُ بْنُ جَعْفَرٍ تَعْنِي يَقْضِينَ .
It is reported from Mu'adha that she asked 'A'isha: Should a menstruating woman complete the prayer (abandoned during the menstrual period)? 'A'isha said: Are you a Hurariya? The wives of the Messenger of Allah (ﷺ) have had their monthly courses, (but) did he order them to make compensation (for the abandoned prayers)? Muhammad b. Ja'far said: (Compensation) denotes their completion.
