أَخْبَرَنَا مُحَمَّدُ بْنُ عِيسَى ، حَدَّثَنَا هُشَيْمٌ ، حَدَّثَنَا يُونُسُ ، عَنْ الْحَسَنِ ، قَالَ :" تُمْسِكُ الْمَرْأَةُ عَنْ الصَّلَاةِ فِي حَيْضِهَا سَبْعًا، فَإِنْ طَهُرَتْ، فَذَاكَ، وَإِلَّا أَمْسَكَتْ مَا بَيْنَهَا وَبَيْنَ الْعَشْرَةَ، فَإِنْ طَهُرَتْ، فَذَاكَ، وَإِلَّا اغْتَسَلَتْ وَصَلَّتْ، وَهِيَ مُسْتَحَاضَةٌ "

Muhammad bin Issa told us, Hushaym told us, Yunus told us, on the authority of Al-Hasan, he said: “A woman abstains from praying seven days during her menstruation. “If she is pure, then that is it. Otherwise, she will retain what is between her and the ten days, then if she is pure, then that is. Otherwise, she will wash and pray, while she is experiencing menstruation.”
