حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ ، عَنْ كَثِيرٍ ، وَحَفْصٍ ، عَنْ الْحَسَنِ فِي الْمُسْتَحَاضَةِ الَّتِي تَعْرِفُ أَيَّامَ حَيْضَتِهَا إِذَا طُلِّقَتْ فَيَطُولُ بِهَا الدَّمُ :" فَإِنَّهَا تَعْتَدُّ قَدْرَ أَقْرَائِهَا ثَلَاثَ حِيَضٍ، وَفِي الصَّلَاةِ إِذَا جَاءَ وَقْتُ الْحَيْضِ فِي كُلِّ شَهْرٍ، أَمْسَكَتْ عَنْ الصَّلَاةِ "
