سَعِيدُ بْنُ مَرْجَانَةَ، عَنْ أُمِّ سَلَمَةَ
[Machine] She said, "There was a woman who used to have blood flow during the time of the Prophet ﷺ . Umm Salamah asked the Prophet ﷺ about her situation, and the Prophet ﷺ said, 'Let her count the number of days and nights on which she used to have menstruation before the blood comes. She should then abandon prayer for that amount of time. Once that period passes, she should perform ghusl (ritual bath) and seek forgiveness with her garment and then pray.'"
أَنَّهَا قَالَتْ إِنَّ امْرَأَةً كَانَتْ تُهَرَاقُ الدِّمَاءَ عَلَى عَهْدِ النَّبِيِّ ﷺ وَإِنَّ أُمَّ سَلَمَةَ سَأَلَتِ النَّبِيَّ ﷺ عَنْ أَمْرِهَا فَقَالَ النَّبِيُّ ﷺ «لِتَنْظُرْ عَدَدَ الْأَيَّامِ وَاللَّيَالِيَ الَّتِي كَانَتْ تَحِيضُ قَبْلَ أَنْ يَكُونَ بِهَا الدَّمُ الَّذِي كَانَ وَقَدْرَهُنَّ مِنَ الشَّهْرِ فَلْتَتْرُكِ الصَّلَاةَ قَدْرَ ذَلِكَ فَإِذَا جَاوَزَتْ ذَلِكَ فَلْتَغْتَسِلْ ثُمَّ لِتَسْتَثْفِرْ بِثَوْبِهَا وَلْتُصَلِّ»
