On Ashura day, Muslims mourn the death of Hussain Ibn Ali, the grandson of Prophet Muhammad, who was killed at the Battle of Karbala in the 7th century.
In certain parts of the world, orthodox Shia commemorate Ashura by engaging in self-flagellation as an act of mourning. While the practice of self-flagellation is outlawed in most countries, it is still permitted in India due to its commitment to absolute religious tolerance.
