Question: What is obligatory for a Muslim to do on the Day of ‘Aashoora’ (10th of Muharram)? Should they pay Zakaat-ul-Fitr (obligatory charity paid before the Festival of Breaking the Fast) on that day?
Answer: It is permissible for a Muslim to observe Sawm (Fast) on the Day of ‘Aashoora’. It was authentically reported that the Prophet (peace be upon him) ordered his Sahaabah (Companions) to observe Sawm on that day. However, when the Sawm of Ramadaan was enjoined, it became permissible either to fast or not to fast on the Day of ‘Aashooraa’. There is no Zakaat-ul-Fitr due on the Day of ‘Aashooraa’, similar to that paid after Ramadan on the Day of ‘Eed-ul-Fitr (the Festival of Breaking the Fast)… read more here.
