I asked ‘Ā’ishah: Why does the menstruating woman make up for her missed fasts but does not make up for the missed prayers?

Mu‘ādhah al-‘Adawiyyah asked the Mother of the believers, ‘Ā’ishah (may Allah be pleased with her): Why does the menstruating woman make up for her missed fasts but does not make up for the missed prayers? She answered her: Are you from the Harūriyyah Kharijites, those who ask excessive questions out of obstinacy and extremism? I said: I am not a Harūriyyah woman, but I am just asking.

She said: We used to menstruate during the time of the Prophet (may Allah's peace and blessings be upon him), and we were commanded to make up for the missed fasts, but not the missed prayers.
