A woman’s menstruation three times in one month and the completion of the waiting period

Question:
Honorable Shaykh, some doctors say that some women, and this is rare, may menstruate three times in one month. Is this possible? And if she menstruates three times in one month, does her waiting period end?

Answer:
This, my brother, was mentioned by the jurists, not by the doctors. The jurists mentioned that it is possible for a woman to menstruate for three days in one month. Therefore, they said that the minimum duration of menstruation is one day and one night; the minimum duration of a menstrual period is one day and one night. This is the minimum for a menstrual period. If her period is one day and one night, then it is possible for her to menstruate for three days in a month. Yes. This occurred during the time of 'Ali (may Allah be pleased with him). This happened during the dispute of 'Ali (may Allah be pleased with him). A woman claimed that she had menstruated three times in one month and that she had completed her waiting period. So he consulted the judge Hiraq, who was present. He said: If she brings evidence, then yes. If she brings evidence from her family members who testify that she menstruated three times, then she is to be believed. Yes.
