7. A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Dawud Mawla’ abu al-Mighra’ al-‘Ijliy from those who narrated to him who have said the following: “I once asked abu ‘Abd Allah , about the case of a woman who experiences Hayd (menses), then the time for her al-Dhuhr Salah (prayer) comes when she finds bleeding. He (the Imam) said, ‘She must examine by means of the day to see if it stops before ten days. If it continued after ten days it, then is because of Istihadah (not Hayd (menses). If bleeding stops (before ten days) she must take Ghusl (bath) and perform Salah (prayer ). 5 I then asked, ‘If a woman whose Hayd (menses) is seven days or eight days all the time and straight then she experiences Hayd (menses) for three days, then bleeding stops, then she finds white discharge not yellow, nor blood . 5 He (the Imam) said, ‘She must take Ghusl (bath) and perform Salah (prayer ) 5 I then said that she performs Salah (prayer) and fasts but bleeding comes again. He (the Imam) said, ‘When she finds blood she must stop Salah (prayer) and fasting . 5 I then said that she finds blood one day and one day finds no blood. He (the Imam) said, ‘When she finds blood she must stop Salah (prayer) and fasting and when she does not find blood, she performs Salah (prayer) and when the number of the days of her Hayd (menses) are complete and bleeding stops, she must perform Salah (prayer). If she finds blood it is then because of Istihadah. I have organized all of her affairs for you.”
