The Day of Ashura is on the 10th day of Muharram in the Islamic calendar and marks the climax of the Remembrance of Muharram but not the Islamic month. This day is well known because of mourning for the martyrdom of Husayn ibn Ali, the grandson of Muhammad at the Battle of Karbala in the year 61 AH (AD 680). This day is really important for shia muslims and fasting in this day is HARAM. The word ashura means simply tenth in Arabic; hence the name of the remembrance, literally translated, means "the tenth day". Islamic scholars, however, give various explanations as to why it is thus called.
