Is it true that there is no menstruation before the age of nine and none after the age of fifty?

The questioner : May Allah reward you. A questioner says: Is it true, O Shaykh, that there is no menstruation before the age of nine and after the age of fifty, and that if a woman menstruates after the age of fifty, she does not have to refrain from prayer and fasting?

The Shaykh : No, that is not correct. A woman may menstruate before the age of nine. Menstruation is known, as stated in the hadith: A woman may also menstruate after the age of fifty. If a woman’s menstruation is continuous, it is menstruation, even if she reaches the age of fifty, sixty, or more. Menstruation is menstruation whenever it occurs, at any age and in any condition. Yes.
