باب الْمُسْتَحَاضَةِ وَغُسْلِهَا وَصَلاَتِهَا ‏
Sahih Muslim 334 b

'A'isha, the wife of the Messenger of Allah (ﷺ) reported:

Umm Habiba b. Jahsh who was the sister-in-law of the Messenger of Allah (ﷺ) and the wife of 'Abd al-Rahman b. Auf, remained mustahada for seven years, and she, therefore, asked for the verdict of Shari'ah from the Messenger of Allah (ﷺ) about it The Messenger of Allah (ﷺ) said: This is not menstruation, but (blood from) a vein: so bathe yourself and offer prayer. 'A'isha said: She took a bath in the wash-tub placed in the apartment of her sister Zainab b. Jahsh, till the redness of the blood came over the water. Ibn Shihab said: I narrated it to Abu Bakr b. 'Abd al-Rahman b. al-Harith b. Hisham about it who observed: May Allah have mercy on Hinda! would that she listened to this verdict. By Lord, she wept for not offering prayer.
وَحَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ الْمُرَادِيُّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى الله عليه وسلم أَنَّ أُمَّ حَبِيبَةَ بِنْتَ جَحْشٍ - خَتَنَةَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَتَحْتَ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ - اسْتُحِيضَتْ سَبْعَ سِنِينَ فَاسْتَفْتَتْ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي ذَلِكَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِنَّ هَذِهِ لَيْسَتْ بِالْحَيْضَةِ وَلَكِنَّ هَذَا عِرْقٌ فَاغْتَسِلِي وَصَلِّي ‏"‏ ‏.‏ قَالَتْ عَائِشَةُ فَكَانَتْ تَغْتَسِلُ فِي مِرْكَنٍ فِي حُجْرَةِ أُخْتِهَا زَيْنَبَ بِنْتِ جَحْشٍ حَتَّى تَعْلُوَ حُمْرَةُ الدَّمِ الْمَاءَ ‏.‏ قَالَ ابْنُ شِهَابٍ فَحَدَّثْتُ بِذَلِكَ أَبَا بَكْرِ بْنَ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ فَقَالَ يَرْحَمُ اللَّهُ هِنْدًا لَوْ سَمِعَتْ بِهَذِهِ الْفُتْيَا وَاللَّهِ إِنْ كَانَتْ لَتَبْكِي لأَنَّهَا كَانَتْ لاَ تُصَلِّي ‏.‏
