Is it permissible to fast the entire month of Muharram?

Question:
May Allah reward you. The Honorable Shaykh says: Is there a hadith regarding fasting the entire month of Muharram? And is there a report that the Prophet (peace and blessings be upon him)

Answer:
It is mentioned in the hadith or the one for which Muharram is named. This indicates the prescription of fasting the month of Muharram. And the most emphasized day of the month of Muharram is the ninth, Ashura. This is the most emphasized day of the month of Muharram. Fasting the day before it is established from the Prophet (peace and blessings be upon him), or fasting the day after it, and this is weak in its narration. But if he missed fasting the ninth day before it, he does not fast the tenth day alone, he does not fast it alone; rather, he fasts a day before it, this is the last option, or a day after it if he missed the first day.
