For those who intend to keep the Muharram fast, it would be kept on the 9^th and 10th, or 10^th and 11^th of Muharram. Thus, the days to fast would be (tomorrow) Friday and Saturday, or Saturday and Sunday.

To not keep these fasts would not constitute a sin, however, fasting would be greatly rewarding for those who have the ability to do so on these given days in the manner described. May Allah bless each of us to do those actions that would attain us closeness towards Him, Ameen.

Rasulullah (SAW) said: The best fasts after the fasting of Ramadan is that of the month of Muharram.
