Muharram FAQ’s (2/5)
Question
How should the fast of the 10th of Muharram be observed?
Answer
Rasulullah (Sallallahu Alayhi Wasallam) advised that an additional fast be kept either a day before or a day after the 10th, as the Jews fasted on the 10th only. This practice ensures that Muslims remain distinct from the practices of non-Muslims.
9. Is it permissible to fast on the day of Ashura (10th of Muharram) only?
It is Mustahab (preferable) to observe the fast of Ashura in one of the following ways:
To fast on the 9th and 10th of Muharram together.
To fast on the 10th and 11th of Muharram together.
To fast on the 9th, 10th, and 11th of Muharram altogether.
It is Makrooh (disliked) to fast only on the 10th of Muharram (the day of Ashura) without accompanying it with a fast on either the 9th or 11th. (Tabyeenul Haqaaiq 1/332)
However, if someone is only able to fast on Ashura for some reason, then there is no problem doing so.
