Tuesday 4 August Arbaeen around the world

The provided text outlines the significance of Arbaeen, a major Shi’ite Muslim observance that marks the end of a forty-day mourning period for Imam Hussein. This historical figure was killed during the Battle of Karbala in 680 AD, an event that fundamentally defined the split between the Sunni and Shiite branches of Islam. Each year, millions of practitioners participate in the Ziara pilgrimage, traveling from dozens of different countries to gather at the holy site in Iraq. Some devotees even complete this journey barefoot as a display of religious devotion and remembrance. Beyond the primary destination in Karbala, the source highlights that secondary commemorations occur in other locations, such as marches in Tehran toward local shrines. Consequently, this event is recognized as the largest annual human gathering in the world, drawing massive crowds of pilgrims and mourners.
