Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet ﷺ said, "Fatima bint Abu Hubaysh said, 'Messenger of Allah, I never become pure - am I permitted to pray?' The Messenger of Allah ﷺ said, 'That is a vein, not menstruation. So when your period approaches, leave off from the prayer, and when its grip leaves, wash the blood from yourself and pray.' "  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ قَالَتْ فَاطِمَةُ بِنْتُ أَبِي حُبَيْشٍ يَا رَسُولَ اللَّهِ إِنِّي لاَ أَطْهُرُ أَفَأَدَعُ الصَّلاَةَ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ إِنَّمَا ذَلِكِ عِرْقٌ وَلَيْسَتْ بِالْحَيْضَةِ فَإِذَا أَقْبَلَتِ الْحَيْضَةُ فَاتْرُكِي الصَّلاَةَ فَإِذَا ذَهَبَ قَدْرُهَا فَاغْسِلِي الدَّمَ عَنْكِ وَصَلِّي  

Yahya related to me from Malik from Nafi from Sulayman ibn Yasarfrom Umm Salama, the wife of the Prophet ﷺ that a certain woman in the time of the Messenger of Allah ﷺ used to bleed profusely, so Umm Salama consulted the Messenger of Allah ﷺ for her, and he said, "She should calculate the number of nights and days a month that she used to menstruate before it started happening, and she should leave off from prayerfor that much of the month. When she has completed that she should do ghusl, bind her private parts with a cloth, and then pray."  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ امْرَأَةً كَانَتْ تُهَرَاقُ الدِّمَاءَ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ فَاسْتَفْتَتْ لَهَا أُمُّ سَلَمَةَ رَسُولَ اللَّهِ ﷺ فَقَالَ لِتَنْظُرْ إِلَى عَدَدِ اللَّيَالِي وَالأَيَّامِ الَّتِي كَانَتْ تَحِيضُهُنَّ مِنَ الشَّهْرِ قَبْلَ أَنْ يُصِيبَهَا الَّذِي أَصَابَهَا فَلْتَتْرُكِ الصَّلاَةَ قَدْرَ ذَلِكَ مِنَ الشَّهْرِ فَإِذَا خَلَّفَتْ ذَلِكَ فَلْتَغْتَسِلْ ثُمَّ لِتَسْتَثْفِرْ بِثَوْبٍ ثُمَّ لِتُصَلِّي  

Yahya related to me from Malik from Hisham ibn Urwa from his father from Zaynab bint Abu Salama that she saw Zaynab bint Jahsh, the wife of Abd ar-Rahman ibn Awf, and she used to bleed as if menstruating. She would do ghusl and pray.  

أَنَّهَا رَأَتْ زَيْنَبَ بِنْتَ جَحْشٍ الَّتِي كَانَتْ تَحْتَ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ وَكَانَتْ تُسْتَحَاضُ فَكَانَتْ تَغْتَسِلُ وَتُصَلِّي  

Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman that al-Qaqa ibn Hakim and Zayd ibn Aslam sent him to Said ibn al-Musayyab to ask how a woman who was bleeding as if menstruating should do ghusl. Said said, "She does a ghusl to cover from the end of one period to the end of the next, and does wudu for every prayer, and if bleeding overtakes her she should bind her private parts."  

فَقَالَ تَغْتَسِلُ مِنْ طُهْرٍ إِلَى طُهْرٍ وَتَتَوَضَّأُ لِكُلِّ صَلاَةٍ فَإِنْ غَلَبَهَا الدَّمُ اسْتَثْفَرَتْ  

Yahya related to me from Malik from Hisham ibn Urwa that his father said, "A woman who bleeds as if menstruating only has to do one ghusl, and then after that she does wudu for each prayer." Yahya said that Malik said, "The position with us is that when a woman who bleeds as if menstruating starts to do the prayer again, her husband can have sexual intercourse with her. Similarly, if a woman who has given birth sees blood after she has reached the fullest extent that bleeding normally restrains women, her husband can have sexual intercourse with her and she is in the same position as a woman who bleeds as if menstruating." Yahya said that Malik said, "The position with us concerning a woman who bleeds as if menstruating is founded on the hadith of Hisham ibn Urwa from his father, and it is what I prefer the most of what I have heard about the matter."  

أَنْ تَغْتَسِلَ غُسْلاً وَاحِدًا ثُمَّ تَتَوَضَّأُ بَعْدَ ذَلِكَ لِكُلِّ صَلاَةٍ قَالَ يَحْيَى قَالَ مَالِكٌ الأَمْرُ عِنْدَنَا أَنَّ الْمُسْتَحَاضَةَ إِذَا صَلَّتْ أَنَّ لِزَوْجِهَا أَنْ يُصِيبَهَا وَكَذَلِكَ النُّفَسَاءُ إِذَا بَلَغَتْ أَقْصَى مَا يُمْسِكُ النِّسَاءَ الدَّمُ فَإِنْ رَأَتِ الدَّمَ بَعْدَ ذَلِكَ فَإِنَّهُ يُصِيبُهَا زَوْجُهَا وَإِنَّمَا هِيَ بِمَنْزِلَةِ الْمُسْتَحَاضَةِ قَالَ يَحْيَى قَالَ مَالِكٌ الأَمْرُ عِنْدَنَا فِي الْمُسْتَحَاضَةِ عَلَى حَدِيثِ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ وَهُوَ أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي ذَلِكَ
