أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ الْحَكَمِ فِي الْحَائِضِ "إِذَا رَأَتْ الطُّهْرَ آخِرَ النَّهَارِ، صَلَّتْ الظُّهْرَ وَالْعَصْرَ، وَإِذَا طَهُرَتْ آخِرَ اللَّيْلِ، صَلَّتْ الْمَغْرِبَ وَالْعِشَاءَ" . .
The Prophet gave the ruling regarding a menstruating woman that when she sees purity at the end of the day, she should perform both Zuhr and Asr prayers, and if she attains purity at the end of the night, she should also perform Maghrib and Isha prayers.
