The Prophet (peace and blessings of Allaah be upon him) fasted on the day of ‘Ashoora’ and urged the people to do likewise as mentioned in the hadeeth narrated by Ibn Abbas who said
“The Prophet (peace and blessings of Allaah be upon him) came to Madeenah and saw the Jews fasting on the day of ‘Ashoora’. He said, “What is this?” They said, “This is a good day, this is the day when Allaah saved the Children of Israel from their enemy and Moosa fasted on this day.” He said, “We are closer to Moosa than you.” So he fasted on this day and told the people to fast”.
It is recommended for whoever intends to fast on the tenth, to do so alongside one other day either the 9th, or the 11th in other to be differ from the jews.
1. Virtues of fasting Ashoora
1. Allah forgives sins of the minor sins of the past year, as for the major sins one has to repent and seek the forgiveness of Allah, or a person they wronged.
Prophet (peace and blessings of Allaah be upon him) said: “Fasting the day of ‘Arafah I hope Allaah will expiate thereby for the year before it and the year after it, and fasting the day of ‘Ashoora’ I hope Allaah will expiate thereby for the year that came before it.” Narrated by Muslim, 1162.
2. The Reward for fasting in Al muharram, is bettered only by Ramadan, Abu Hurayrah (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The best fasting after Ramadaan is the month of Allaah Muharram, and the best prayer after the obligatory prayer is prayer at night.” Narrated by Muslim, 1163.
2. Common mistakes committed during Ashoora
1.Celebrating that day is an innovation (bid’ah), and has no basis whatsoever in islam, no gathering or cooking
Shaykh Ibn Baaz (may Allaah have mercy on him) said: This is an abhorrent evil and reprehensible innovation which must be abandoned; it is not permissible to take part in it and it is not permissible to eat the food that is offered.
2.What the Shi’ah do on ‘Ashoora’ of beating their chests, slapping their cheeks, striking their shoulders with chains and cutting their heads with swords to let the blood flow are all innovations that have no basis in Islam.
These is wrong as the prophet SAW lost prominent members of ahlul bait during his life such as Khadijah his beloved wife, his uncle and all his children except fatimah,and he didn’t beat himself nor harm himself in any way, May Allah forgive and guide us all ameen
