The Day of Ashura is commemorated by Shi’a Muslims as a day of mourning for the martyrdom of Husayn ibn Ali, the grandson of Muham- mad at the Battle of Karbala on 10 Muharram in the year 61 AH.
According to Eighth Shia Imam, Ali al-Rida, it must be observed as a day of inactivity, sorrow and total disregard of worldly cares.
Part of the event the Azadari ritual where suffering and cutting the body with knives or chains (matam) is performed. Something that was banned by the Shi’a Marja’ Ali Khamenei, Supreme Leader of Iran and Hezbollah in Lebanon but still is practiced in Bangladesh and India
