حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا شَرِيكٌ، عَنْ أَبِي الْيَقْظَانِ، عَنْ عَدِيِّ بْنِ ثَابِتٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ فِي الْمُسْتَحَاضَةِ " تَدَعُ الصَّلاَةَ أَيَّامَ أَقْرَائِهَا الَّتِي كَانَتْ تَحِيضُ فِيهَا ثُمَّ تَغْتَسِلُ وَتَتَوَضَّأُ عِنْدَ كُلِّ صَلاَةٍ وَتَصُومُ وَتُصَلِّي " .
