The virtues of fasting ‘Ashura
The Prophet, peace be upon him, said:
“For fasting the day of ‘Ashura, I hope that Allah will accept it as expiation for the year that went before.” [Reported by Muslim, 1976]
Ibn ‘Abbas, may Allah be pleased with them both, said:
“I never saw the Messenger of Allah, upon whom be peace, so keen to fast any day and give it priority over any other than this day, the day of ‘Ashura, and this month, meaning Ramadhan.” [Reported by al-Bukhari, 1867]
