Is it permissible to fast the six days before making up missed days of Ramadan?

Question:
May Allah reward you, Honorable Shaykh. The questioner asks: Is it permissible to fast the six days before making up missed days of Ramadan?

Answer:
No. The Messenger (peace and blessings be upon him) said: He fasted, meaning the entire month, and then followed it up. Look, "followed it up" and "followed it up" only happens after the month is complete. So he fasts the make-up days first, then he fasts the six days. Yes.
