Haidh (Menstruation or Period)

10^th to 18^th ….is haidh

19^th to 20^th ….is istihadha

Scenario 4:  If a woman in the last two months has seen blood between the 10^th and 18^th BUT this month she saw blood between the 10^th and 20^th, then what is her duty? In this situation all 10 days is ‘haidh’, because the flow does not exceed 10 days. This scenario is just like scenario 1.

Woman having the habit of duration: As was mentioned earlier this is a woman who has seen blood for a fixed duration but not for a fixed time (date wise) in the past 2 months. When a woman under this category sees blood for 10 days (and it has all the signs of haidh) then it is all haidh, but if she sees it for more than 10 days then blood seen during the days of habit of duration is period and the rest is istihadha.

Some scenarios of women who have a ‘Habit of Duration’

Scenario 1:  If a woman in the last two months has seen blood for 8 days BUT this month she sees it for 13 days, what is her duty? In this situation she should consider first 8 days as ‘haidh’ and the rest as ‘istihadha’, because she had a habit of 8 days and this month the flow was more than 10 days.

Scenario 2:  If a woman in the last 2 months has seen blood for 8 days BUT this month she sees it for 10 days, what is her duty? 

In this situation she should consider all 10 days as ‘haidh’, as the flow was not more than 10 days.

Woman who have a habit of time: As was mentioned earlier this is a woman who has seen blood on a particular date in the past 2 months but has no fixed duration. When a woman under this category sees blood for 10 days (and it has all the signs of haidh) then it is all haidh, but if she sees blood for more than 10 days then she must follow the guidelines below:

If the blood seen has signs of haidh then the number of days it has the signs of haidh is ‘haidh’, the rest is istihadha. (If the blood has the signs of haidh and the same signs remain for 13 days, then it is as if there were no signs)
