[Machine] We used to be in her room, and one of us would menstruate, then become purified, and wash herself and pray, then she would have a slight yellow discharge. She would command us to refrain from prayers until we could only see pure whiteness.  

الدارمي:٨٨٩أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الرَّقَاشِيُّ عَنْ يَزِيدَ بْنِ زُرَيْعٍ حَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ قَالَ حَدَّثَتْنِي فَاطِمَةُ عَنْ أَسْمَاءَ قَالَتْ

كُنَّا نَكُونُ فِي حِجْرِهَا فَكَانَتْ إِحْدَانَا تَحِيضُ ثُمَّ تَطْهُرُ فَتَغْتَسِلُ وَتُصَلِّي ثُمَّ تَنْكُسُهَا الصُّفْرَةُ الْيَسِيرَةُ «فَتَأْمُرُنَا أَنْ نَعْتَزِلَ الصَّلَاةَ حَتَّى لَا نَرَى إِلَّا الْبَيَاضَ خَالِصًا»

[Machine] We were in her room with her brother's daughters, and one of us would purify herself, then pray, and then she would prostrate with a little yellowish secretion. She would ask her about it, and she would say, "Leave prayer until you see pure whiteness."  

البيهقي:١٥٩٣أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو بَكْرِ بْنُ إِسْحَاقَ الْفَقِيهُ ثنا إِبْرَاهِيَمُ بْنُ إِسْحَاقَ الْحَرْبِيُّ ثنا أَحْمَدُ بْنُ يُونُسَ ثنا زُهَيْرٌ قَالَ وَأَخْبَرَنَا إِبْرَاهِيَمُ ثنا أَبُو بَكْرٍ يَعْنِي ابْنَ أَبِي شَيْبَةَ ثنا عَبْدُ الْأَعْلَى عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ عَنْ فَاطِمَةَ عَنْ أَسْمَاءَ قَالَتْ

كُنَّا فِي حِجْرِهَا مَعَ بَنَاتِ أَخِيهَا فَكَانَتْ إِحْدَانَا تَطْهُرُ ثُمَّ تُصَلِّي ثُمَّ تَنْتَكِسُ بِالصُّفْرَةِ الْيَسِيرَةِ فَتَسْأَلُهَا فَتَقُولُ اعْتَزِلْنَ الصَّلَاةَ مَا رَأَيْتُنَّ ذَلِكَ حَتَّى تَرَيْنَ الْبَيَاضَ خَالِصًا
