Purity: Accepting a Woman's Statement Regarding Ḥayḍ
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 453:
If a woman says she is ḥāʾiḍ or that her ḥayḍ has stopped, in the event that she is not suspected to be someone whose word in this case cannot be accepted, her statement must be accepted. However, if she is suspected to be someone whose word in this case cannot be accepted, then accepting her statement is problematic [i.e. based on obligatory precaution, her statement must not be accepted].
