We would like to remind you that in shaa Allah tomorrow is the 10th of Muharram ("Ashoora") and it is recommended for us to fast. You may fast Saturday and Sunday, 10th & 11th of Muharram.
What is Ashoora?
The 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
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.” - al-Bukhaari, 1865
