If the time of menstruation coincides with her fasting on the white days, what should she do?

The questioner:
May Allah reward you. In her last question, she says: I am a girl accustomed to fasting the white days of every month, praise be to Allah, and in some months my period comes to me on the third day in the afternoon, so what is obligatory for me to do if this happens repeatedly?

The Shaykh:
If your period comes in the afternoon while you are fasting, the fast is invalid, the fast is invalid, and what is required is to fast three days of every month, whether from the beginning, the middle, or the end. If it is easy for the white days to coincide, that is better; otherwise, it is sufficient to fast the three days from the beginning or the end of the month. Yes.

The questioner:
She can maintain this, O Shaykh, she wants the habit of fasting three days of every month not to be broken.

The Shaykh:
Yes, this is achieved by fasting the three days at any time of the month. Yes.
