'Aishah the wife of the Prophet said: "Umm Habibah Jahsh experienced prolonged non-menstrual bleeding for seven years when she was married to 'Abdur-Rahman bin 'Awf. She complained about that to the Prophet and the Prophet said: 'That is not menstruation, rather it is a vein, so when the time of your period comes, leave the prayer, and when it is over, take a bath and perform prayer.'" 'Aishah said: "She used to bathe for every prayer and then perform the prayer. She used to sit in a washtub belonging to her sister Zainab bint Jahsh and the blood would turn the water red."  

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتِ اسْتُحِيضَتْ أُمُّ حَبِيبَةَ بِنْتُ جَحْشٍ وَهِيَ تَحْتَ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ سَبْعَ سِنِينَ فَشَكَتْ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ إِنَّ هَذِهِ لَيْسَتْ بِالْحَيْضَةِ وَإِنَّمَا هُوَ عِرْقٌ فَإِذَا أَقْبَلَتِ الْحَيْضَةُ فَدَعِي الصَّلاَةَ وَإِذَا أَدْبَرَتْ فَاغْتَسِلِي وَصَلِّي قَالَتْ عَائِشَةُ فَكَانَتْ تَغْتَسِلُ لِكُلِّ صَلاَةٍ ثُمَّ تُصَلِّي وَكَانَتْ تَقْعُدُ فِي مِرْكَنٍ لأُخْتِهَا زَيْنَبَ بِنْتِ جَحْشٍ حَتَّى إِنَّ حُمْرَةَ الدَّمِ لَتَعْلُو الْمَاءَ
