وَعَنْ عَدِيِّ بْنِ ثَابِتٍ عَنْ أَبِيهِ عَنْ جَدِّهِ (
قَالَ يَحْيَى بْنُ مَعِينٍ: جَدُّ عَدِيٍّ اسْمُهُ دِينَارٌ) عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ فِي الْمُسْتَحَاضَةِ: «تَدَعُ الصَّلَاةَ أَيَّامَ أَقْرَائِهَا الَّتِي كَانَتْ تَحِيضُ فِيهَا ثُمَّ تَغْتَسِلُ وَتَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ وَتَصُومُ وَتُصَلِّي»
Adi ibn Thabit quoted his father as saying that his grandfather (Adi’s grandfather’s name is given as Dinar by Yahya ibn Main) reported the Prophet (sallallahu alayhi wa sallam) as saying regarding a woman who has a prolonged flow of blood that she should abandon prayer during as many days as she used to have her courses, then wash, perform ablution for every prayer, fast and pray.
