Ruling on performing the fast of the six days of Shawwal before making up missed days of Ramadan

The questioner : Yes, she fasted the six days and she fasted the days of the menstrual period. Yes, that is correct. He said it is not permissible.

The Shaykh : Meaning, she fasted the six days before making up the missed days? This is a mistake.

The questioner : And then she fasted the days of the period? No. What?

The Shaykh : It is necessary to make up the missed days first; the missed days must be made up before fasting the six days of Shawwal, because the Prophet (peace and blessings be upon him) said , so he began with fasting Ramadan. And if a woman has missed days from Ramadan that she did not fast,

The questioner : five days. If I fasted twenty-five days of Ramadan, did I not fast the whole month? No, by Allah. And then she fasted the six days and the five days. In any case, the fasting is valid; the fasting of the five days to make up the missed days is valid. Yes?

The Shaykh : And is the fasting of the six days valid?

The questioner : Because you did not know, but the reward attached to it is not valid; no,

The Shaykh : the reward attached to this is not obtained. Yes, and after this year, if Allah wills, will you start by making up the missed days before fasting the six days?

The questioner : If Allah wills, I just wanted to ask for clarification.
