Let us suppose her duration of haidh is 8 days, then 8 days will be nifas and the remaining 5 days will be istihadha. (Please check Question 1 below for another scenario). Scenario 2: This woman has no fixed duration and no fixed time when she sees blood during haidh. She delivered a baby and has been seeing blood for 13 days, is this blood all nifas? Since this woman has no habit of duration, then she should consider the first 10 days as nifas and the remaining 3 days as istihadha.
(Please check Question 2 below for another scenario). Scenario 3: This woman has a habit of time and duration during haidh that means she sees blood of haidh on a specific date each month and for a fixed duration. She delivers a baby and sees blood for 14 days., is this blood all nifas? Let us suppose that her duration of haidh is 7 days, then 7 days will be nifas and the remaining 7 days will be istihadha.
(Please check Question 3 below for another scenario) Scenario 4: This woman has a habit of time during haidh, which means this woman sees blood of haidh on a specific date each month. She delivers a baby and sees blood for more than 13 days. Then she should consider the first 10 days as nifas and the remaining 3 days as istihadha. (Please check Question 4 below for another scenario).
Question 1: Keeping scenario 1 in mind, if a woman who has a habit of duration during haidh, delivers a baby and sees blood for 30 days, what is the ruling? Answer: The first 8 days are nifas (her habit of duration of haidh in this scenario) . The next 10 days are going to be counted as istihadha. The next 8 days are haidh (If it still has the signs of haidh. If it does not have the signs of haidh, then she must consult her family to see if they had the same pattern after delivery).
The final 4 days are istihadha Question 2: Keeping scenario 2 in mind, where a woman does not have a habit of time and duration when haidh is concerned, if she delivers a baby and sees blood for 30 days, what is the ruling? Answer: First 10 days are nifas (since she has no habit of time and duration) . The next 10 days are istihadha. The final 10 days are haidh (if the blood continues to have the signs of haidh.
Otherwise if for example, 8 days had signs, then 8 count towards haidh and 2 to istihadha. If for example, the blood had no signs, then she must contact her family for the number of days of duration of haidh).
