Ash-Shama'il al-Muhammadiyah 308

Translation

"‘Ashura' was a day on which Quraish used to fast in the pagan era [al-jahiliyya], and Allah’s Messenger ﷺ used to keep it as well. Hence, when he arrived in Medina, he kept its fast and commanded its observance. Then, when Ramadan was decreed, [the fast of] Ramadan became the obligatory religious duty, and 'Ashura' was omitted, so one is free to fast this day or not to fast it.”
