Is it prescribed to fast the month of Muharram except for a few days?

Question:
What is the ruling on one who fasts the month of Muharram and leaves out three or four days? Is this mentioned in the Shari'ah?

Answer:
There is no harm, there is no harm. The Prophet (peace and blessings be upon him) said, the Chosen One (peace be upon him) said: and that is 'Ashura. So if he fasts, or if we say he fasts more, or if he fasts only 'Ashura with a day before it or after it, all of this is good. And if he does not fast, there is no blame on him; it is only a voluntary act. If he fasts, that is better. If he fasts more, that is even better. If he observes 'Ashura, observing the tenth day, and the day before it, the ninth, or the day after it, the eleventh, that is sufficient. Yes.
