Narrated Aisha, Ummul Mu'minin:

A woman had a prolonged flow of blood in the time of the Messenger of Allah ﷺ. She was commanded to advance the afternoon prayer and delay the noon prayer, and to take a bath for them only once; and to delay the sunset prayer and advance the night prayer and to take a bath only once for them; and to take a bath separately for the dawn prayer.

I (Shu'bah) asked AbdurRahman: (Is it) from the Prophet ﷺ? I do not report to you anything except from the Prophet ﷺ.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتِ اسْتُحِيضَتِ امْرَأَةٌ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَأُمِرَتْ أَنْ تُعَجِّلَ الْعَصْرَ وَتُؤَخِّرَ الظُّهْرَ وَتَغْتَسِلَ لَهُمَا غُسْلاً . وَأَنْ تُؤَخِّرَ الْمَغْرِبَ وَتُعَجِّلَ الْعِشَاءَ وَتَغْتَسِلَ لَهُمَا غُسْلاً وَتَغْتَسِلَ لِصَلاَةِ الصُّبْحِ غُسْلاً . فَقُلْتُ لِعَبْدِ الرَّحْمَنِ أَعَنِ النَّبِيِّ ﷺ فَقَالَ لاَ أُحَدِّثُكَ عَنِ النَّبِيِّ ﷺ بِشَىْءٍ .
