Those Who Said: She Should Perform Ghusl From One Purity To The Other
Arabic hadith text
حَدَّثَنَا أَحْمَدُ بْنُ سِنَانٍ الْقَطَّانُ الْوَاسِطِيُّ، حَدَّثَنَا يَزِيدُ، عَنْ أَيُّوبَ بْنِ أَبِي مِسْكِينٍ، عَنِ الْحَجَّاجِ، عَنْ أُمِّ كُلْثُومٍ، عَنْ عَائِشَةَ، فِي الْمُسْتَحَاضَةِ تَغْتَسِلُ - تَعْنِي مَرَّةً وَاحِدَةً - ثُمَّ تَوَضَّأُ إِلَى أَيَّامِ أَقْرَائِهَا ‏.‏
Translation
'Aishah said about the woman who has a prolonged flow of blood

She should take bath, i.e. only once; then she should perform ablution until he next menstrual period.
