abudawud:291Muḥammad b. Isḥāq al-Musayyabī from my father > Ibn Abū Dhiʾb > Ibn Shihāb > ʿUrwah And ʿAmrah b. ʿAbd al-Raḥman > ʿĀʾishah

Umm Habibah had a prolonged flow of blood for seven years. The Messenger of Allah ﷺ commanded her to take bath; so she used to take bath for every prayer.  

أبو داود:٢٩١حَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ حَدَّثَنِي أَبِي عَنِ ابْنِ أَبِي ذِئْبٍ عَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ عَنْ عَائِشَةَ

أَنَّ أُمَّ حَبِيبَةَ اسْتُحِيضَتْ سَبْعَ سِنِينَ فَأَمَرَهَا رَسُولُ اللَّهِ ﷺ أَنْ تَغْتَسِلَ فَكَانَتْ تَغْتَسِلُ لِكُلِّ صَلاَةٍ

bukhari:327Ibrāhīm b. al-Mundhir > Maʿn > Ibn Abū Dhiʾb > Ibn Shihāb > ʿUrwah > ʿAmrah

(the wife of the Prophet) Um Habiba got bleeding in between the periods for seven years. She asked Messenger of Allah ﷺ about it. He ordered her to take a bath (after the termination of actual periods) and added that it was (from) a blood vessel. So she used to take a bath for every prayer.  

البخاري:٣٢٧حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ قَالَ حَدَّثَنَا مَعْنٌ قَالَ حَدَّثَنِي ابْنُ أَبِي ذِئْبٍ عَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ وَعَنْ عَمْرَةَ

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ أُمَّ حَبِيبَةَ اسْتُحِيضَتْ سَبْعَ سِنِينَ فَسَأَلَتْ رَسُولَ اللَّهِ ﷺ عَنْ ذَلِكَ فَأَمَرَهَا أَنْ تَغْتَسِلَ فَقَالَ هَذَا عِرْقٌ فَكَانَتْ تَغْتَسِلُ لِكُلِّ صَلاَةٍ
