Chapter: Concerning The Woman Who Has Istihadah, And (Those Scholars) Who Stated That She Should Leave The Prayer For The Number Of Days Which She Used To Menstruate
(109)
باب فِي الْمَرْأَةِ تُسْتَحَاضُ وَمَنْ قَالَ تَدَعُ الصَّلاَةَ فِي عِدَّةِ الأَيَّامِ الَّتِي كَانَتْ تَحِيضُ
Sunan Abi Dawud 277
This tradition has been transmitted through the chain of narrators like that of al-Laith to the same effect. It says; She should abandon prayer considering that period (she used to menstruate). When the time of prayer approaches, she should take a bath, tie a cloth over her private parts and offer prayer.
حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا صَخْرُ بْنُ جُوَيْرِيَةَ، عَنْ نَافِعٍ، بِإِسْنَادِ اللَّيْثِ وَبِمَعْنَاهُ قَالَ ‏ "‏ فَلْتَتْرُكِ الصَّلاَةَ قَدْرَ ذَلِكَ ثُمَّ إِذَا حَضَرَتِ الصَّلاَةُ فَلْتَغْتِسِلْ وَلْتَسْتَثْفِرْ بِثَوْبٍ ثُمَّ تُصَلِّي ‏"‏ ‏.‏
