Three types of Nafsa'

1. A woman whose post-natal bleeding does not ex­ceed ten days. In such a case all the days of bleeding will be considered nifas.

2. A woman whose post-natal bleeding exceeds ten days and, as far as her menstrual cycles are concerned, she is a zatu 'l-'adah with a fixed number of days. In this case the days equal to the duration of her menstruation will be regarded as nifasand the remaining days as istihazah.

3. A woman whose post-natal bleeding exceeds ten days and she is not a zatu 'l-'adah. In this case she should look at the duration of her relatives' menstruation and then consider the same number of days as her nifas. If the duration of her relatives' menses is less than ten, then (a) she should count those days as nifas and (b) after that she should act on precaution up to the tenth day.
