Alhamdulillah, we are in the blessed month of Muharram. The 10th of Muharram is a very special day known as the Day of Ashura. This year, the Day of Ashura will be on Saturday, August 29th inshaAllah.
The Prophet (ﷺ) taught us in an authentic narration found in Sahih Muslim, that the Day of Ashura is from among the days that are dedicated to Allah (SWT).
He told us that this was the day on which Allah (SWT) displayed His power, protected, and rescued Prophet Musa (A) and his followers from the tyrant Firawn. (Sahih Bukhari).
The Prophet (ﷺ) said that as Muslims, we have a very strong and close relationship with Prophet Musa (A), and he encouraged us to fast on this day.
We also learn that there is a tremendous reward for fasting on the Day of Ashura. All the mistakes and sins of the previous year are erased from the person who fasts on this special day. (Sahih Muslim).
There are different opinions as to which set of days to fast. Everyone is in agreement that we should fast on the 10th of Muharram. One may fast on the 9th and 10th, the 10th and 11th, or all three days—and Allah (SWT) knows best. 
Let’s mark our calendars and inshaAllah, make the most of this special opportunity.
