It was narrated that 'Aishah said:

"Umm Habibah bint Jahsh consulted the Messenger of Allah ﷺ and said: 'O Messenger of Allah, I suffer from Istihadah (non-menstrual vaginal bleeding).' He said: 'That is a vein, so perform Ghusl and pray.' And she used to perform Ghusl for every prayer."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتِ اسْتَفْتَتْ أُمُّ حَبِيبَةَ بِنْتُ جَحْشٍ رَسُولَ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي أُسْتَحَاضُ . فَقَالَ " إِنَّمَا ذَلِكِ عِرْقٌ فَاغْتَسِلِي وَصَلِّي " . فَكَانَتْ تَغْتَسِلُ لِكُلِّ صَلاَةٍ .
