Ashura (Arabic: ??????????, ?Ashura?, [?a??u?'ra??]) is a day of commemoration in Islam. It occurs annually on the 10th of Muharram, the first month of the Islamic calendar. Among Shia Muslims, Ashura is observed through large demonstrations of high-scale mourning as it marks the death of Husayn ibn Ali (a grandson of Muhammad), who was beheaded during the Battle of Karbala in 680 AD.[4] Ashura is also respected by Sunnis, however, while Husayn's death is also regarded as a great tragedy by Sunnis, open displays of mourning are either discouraged or outright prohibited, depending on the specific act.[5]
