That which is recommended for the Muslim on the day of 'Aashooraa.
Question: What is obligatory upon the Muslim to do on the day of 'Aashooraa.. (tenth day of Muharram), and is Zakaat al-Fitr obligatory (on that day)?
Response: It is legislated for the Muslim to fast on the day of 'Aashooraa., for that which has been confirmed that the Prophet (sal-Allaahu alayhe wa sallam) ordered fasting on (the day of) 'Aashooraa., however, when (the fasting of) Ramadhaan was obligated, whoever preferred to fast ('Aashooraa.) did so and whoever preferred not to (do so) did not. And there is no Zakaat al-Fitr (to be paid) on the day of 'Aashooraa. as there is on Eed al-Fitr after the month of Ramadhaan.
And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu `alayhe wa sallam) and his family and his companions.

The permissibility of fasting on the day of 'Aashooraa. only
Question: Is it permissible to fast 'Aashooraa. just one day?
Response: It is permissible to fast the day of 'Aashooraa. (tenth day of Muharram) just one day, however, it is better to fast the day before it or the day after it (also) and this is the established Sunnah of the Prophet (sal-Allaahu `alayhe wa sallam) who said: ((If I am (still) here next year, then certainly I shall fast the ninth (day of Muharram))), (reported by) Muslim, Ahmad, Ibn Maajah, Ibn Abee Shaybah, at-Tahaawee, al-Bayhaqee and al-Baghawee]. Ibn 'Abbaass (radhi-yallaahu 'anhumaa) said: ((along with the tenth (day of Muharram))).
And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu `alayhe wa sallam) and his family and his companions.
