QUESTION:
People fast first tenth days of Muharram. Is it a Sunnah? What is the priority of this month and why do we fast in it?
ANSWER:
The Prophet salla Allahu alaihi wa sallam said that the best month to fast after Ramadan is the month of Moharram.
Fasting only the first 10 days of it is not part of the Sunnah.
Fasting the 9th and 10th is a great Sunnah as it forgives the sins of a whole year. This is the day that Allah drowned Pharos and saved Musa peace be upon him.
And Allah Knows Best
