Virtues of Muharram

It is narrated from Abu Huraira that the Prophet [SAWS] said, "The best fasts after (the fasts of) Ramadan are the fasts of the month of Allah, Muharram". [Reported by Muslim]

Muharram is among the four sacred months...
“Verily, the number of months with Allaah is twelve months (in a year), so it was ordained by Allaah on the Day when He created the heavens and the earth; of them, four are sacred. That is the right religion, so wrong not yourselves therein…” [al-Tawbah 9:36]

Yaum al-Ashoora falls in this blessed month...
Ibn ‘Abbaas (may Allaah be pleased with him) said: “The Prophet (peace and blessings of Allaah be upon him) came to Madeenah and saw the Jews fasting on the day of ‘Aashooraa’. He said, ‘What is this?’ They said, ‘This is a righteous day, it is the day when Allaah saved the Children of Israel from their enemies, so Moosa fasted on this day.’ He said, ‘We have more right to Moosa than you,’ so he fasted on that day and commanded [the Muslims] to fast on that day.” (Reported by al-Bukhaari, 1865).

According to a report narrated by al-Bukhaari: “… so we fast on this day to venerate it.” A version narrated by Imaam Ahmad adds: “This is the day on which the Ark settled on Mount Joodi, so Nooh fasted this day in thanksgiving.” “and commanded [the Muslims] to fast on that day” – according to another report also narrated by al-Bukhaari: “He said to his Companions: ‘You have more right to Moosa than they do, so fast on that day.' ”

Ibn ‘Abbaas (may Allaah be pleased with them both) said: “I never saw the Messenger of Allaah (peace and blessings of Allaah be upon him) so keen to fast any day and give it priority over any other than this day, the day of ‘Aashooraa’, and this month, meaning Ramadaan.” (Reported by al-Bukhaari, 1867).

The Prophet (peace and blessings of Allaah be upon him) said: “For fasting the day of ‘Aashooraa’, I hope that Allaah will accept it as expiation for the year that went before.” (Reported by Muslim, 1976).

Which day is Ashoora?
Al-Nawawi (may Allaah have mercy on him) said: “ ‘Aashooraa’ and Taasoo’aa’ are two elongated names [the vowels are elongated] as is stated in books on the Arabic language. Our companions said: ‘Aashooraa’ is the tenth day of Muharram and Taasoo’aa’ is the ninth day. This is our opinion, and that of the majority of scholars. This is the apparent meaning of the ahaadeeth and is what we understand from the general wording. It is also what is usually understood by scholars of the language.” (al-Majmoo’)

Imaam al-Nawawi (may Allaah 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 Allaah have mercy on him): “Fasting the day of ‘Arafaah expiates for two years, and the day of ‘Aashooraa’ expiates for one year. If when a person says ‘Aameen’ it coincides with the ‘Aameen’ of the angels, he will be forgiven all his previous sins… Each one of the things that we have mentioned will bring expiation. If there are minor sins for which expiation is needed, expiation for them will be accepted; if there are no minor sins or major sins, good deeds will be added to his account and he will be raised in status… If he had committed major sins but no minor sins, we hope that his major sins will be reduced.” (al-Majmoo’ Sharh al-Muhadhdhab, part 6, Sawm Yawm ‘Arafaah).
