"Umm 'Atiyah would never mention the Messenger of Allah ﷺ without saying: 'May my father be ransomed for him.' I said: 'Did you hear the Messenger of Allah ﷺ say such and such?' And she said: 'Yes, may my father be ransomed for him.' He said: 'Let the mature girls, virgins staying in seclusion, and menstruating woman go out and witness the good occasions and the supplications of the Muslims, but let the menstruating women keep away from the prayer place.'" (Using translation from Nasāʾī 390)  

كَانَتْ أُمُّ عَطِيَّةَ لَا تَذْكُرُ رَسُولَ اللهِ ﷺ أَبَدًا إِلَّا قَالَتْ بِأَبَا فَقُلْتُ أَسَمِعْتِ رَسُولَ اللهِ ﷺ يَقُولُ «كَذَا وَكَذَا؟» قَالَتْ نَعَمْ بِأَبَا قَالَ «لِتَخْرُجِ الْعَوَاتِقُ ذَوَاتُ الْخُدُورِ وَالْحُيَّضُ فَيَشْهَدْنَ الْخَيْرَ وَدَعْوَةَ الْمُسْلِمِينَ وَيَعْتَزِلْنَ الْحُيَّضُ الْمُصَلَّى» مُخْتَصَرٌ
