The longer of the waiting period for widowhood and the waiting period for divorce in the author's statement

Question:
We say, Honorable Shaykh, may Allah grant you success, regarding the author's (may Allah have mercy on him) statement: "The longer of the waiting period for widowhood and the waiting period for divorce." The waiting period for widowhood is not always the longer one, is it? Because it is four months and ten days?

Answer:
My brother, understand, do not make a mistake. Menstruation is not always continuous. Sometimes some women menstruate, but only once a year. Menstruation can be long or short. That is to say, the period of purity between two menstruations is sometimes long and sometimes short. Some women menstruate once a year, requiring three years to menstruate three times. And this is longer than four months, yes.
