What is the legal ruling regarding prayer and fasting in the event of continuous bleeding for more than 14 days after the menstrual period, with the blood described as black and containing pieces of flesh?

The maximum duration for menstruation is fifteen days. Any blood a woman sees within this period is considered menses, including any intervening periods of purity. If the blood, and any purity interspersed within it, exceeds fifteen days, then it is Istihada (non-menstrual vaginal bleeding).

In this case: - If the woman has a previous regular habit, then its duration is menstruation, and anything beyond that is Istihada. - If she does not have a regular habit, she should differentiate between the types of blood. - If she cannot differentiate, she should estimate six or seven days as menstruation based on investigation, and anything beyond that is Istihada.

Ghusl (ritual bath) is obligatory upon the completion of the menstrual period. During Istihada, ablution (Wudu') is obligatory for each prayer after its time has begun.
