Abu Hurayrah (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings of Allah be upon him) said: 'The best of fasting after Ramadhan is fasting Allah's month of Muharram.' " [Reported by Muslim, 1982]

'ASHURA' IN HISTORY

Ibn 'Abbas (may Allah be pleased with him) said: "The Prophet (peace and blessings of Allah be upon him) came to Madinah and saw the Jews fasting on the day of 'Ashura'. He said, 'What is this?' They said, 'This is a righteous day, it is the day when Allah saved the Children of Israel from their enemies, so Musa fasted on this day.' He said, 'We have more right to Musa than you,' so he fasted on that day and commanded [the Muslims] to fast on that day." [Reported by al-Bukhari, 1865]

Ibn 'Abbas (may Allah be pleased with them both) said: "I never saw the Messenger of Allah (peace and blessings of Allah be upon him) 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]

'Abdullah ibn 'Abbas (may Allah be pleased with them both) said: "When the Messenger of Allah (peace and blessings of Allah be upon him) fasted on 'Ashura' and commanded the Muslims to fast as well, they said, 'O Messenger of Allah, it is a day that is venerated by the Jews and Christians.' The Messenger of Allah (peace and blessings of Allah be upon him) said, 'If I live to see the next year, in sha Allah, we will fast on the ninth day too.' But it so happened that the Messenger of Allah (peace and blessings of Allah be upon him) passed away before the next year came." [Reported by Muslim, 1916]

FASTING 'ASHURA' - FOR WHAT DOES IT OFFER EXPIATION?

Imam an-Nawawi (may Allah have mercy on him) said: "It expiates for all minor sins, i.e., it brings forgiveness of all sins except major sins." Then he said (may Allah have mercy on him): "Fasting the day of 'Arafah expiates for two years, and the day of 'Ashura' expiates for one year.
