Salah Is Not Obligatory For Menstruating Women
أَخْبَرَنَا عَمْرُو بْنُ زُرَارَةَ، قَالَ أَنْبَأَنَا إِسْمَاعِيلُ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، عَنْ مُعَاذَةَ الْعَدَوِيَّةِ، قَالَتْ سَأَلَتِ امْرَأَةٌ عَائِشَةَ أَتَقْضِي الْحَائِضُ الصَّلاَةَ فَقَالَتْ أَحَرُورِيَّةٌ أَنْتِ قَدْ كُنَّا نَحِيضُ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلاَ نَقْضِي وَلاَ نُؤْمَرُ بِقَضَاءٍ .
It was narrated that Mu'adhah Al-'Adawiyyah said: "A woman asked 'Aishah: 'Should a menstruating woman make up the Salah she misses? She said: 'Are you a Haruri? [1] We used to menstruate during the time of Allah's Messenger (ﷺ) but we did not make up the missed Salah nor were we commanded to do so.'" [1] Meaning are you one of the Khawarij. Harura is a place associated with a group of the Khawarij.
