The menstruating woman is commanded to make up for the fasts and would not make up for the prayers

 180. Mu´adhah said: I aksed ´Aishah: ´´Why a menstruating woman makes up for the missing days of fasting, but not for the missing prayers?´´ she said: ´´Are you a Haruiyah?´´ I said: ´´I am not a Haruriyah, but I am asking.´´ She said: ´´We passed through this (period of menstruating), and we were ordered to make up for the missed out days of fasts, but not the missed out prayers.´´
