أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ امْرَأَةً، مُسْتَحَاضَةً عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم قِيلَ لَهَا إِنَّهُ عِرْقٌ عَانِدٌ وَأُمِرَتْ أَنْ تُؤَخِّرَ الظُّهْرَ وَتُعَجِّلَ الْعَصْرَ وَتَغْتَسِلَ لَهُمَا غُسْلاً وَاحِدًا وَتُؤَخِّرَ الْمَغْرِبَ وَتُعَجِّلَ الْعِشَاءَ وَتَغْتَسِلَ لَهُمَا غُسْلاً وَاحِدًا وَتَغْتَسِلَ لِصَلاَةِ الصُّبْحِ غُسْلاً وَاحِدًا .
It was narrated from 'Aishah that a woman who suffered from Istihadah at the time of the Messenger of Allah (PBUH) was told that it was a stubborn vein (i.e., one that would not stop bleeding). She was told to delay Zuhr and bring 'Asr forward, and to perform one Ghusl for both, and to delay Maghrib and bring 'Isha' forward, and to perform one Ghusl for both, and she would perform one Ghusl for Subh.
