The opening as it read in 2025

Mourning of Al-Muharram ( Arabic : عَزَاءُ ٱلْمُحَرَّمِ , romanized : ʿAzāʾ Al-Muḥarram ; Persian : عزاداری محرم , romanized : ʿAzādārī-i Muḥarram ; Azerbaijani : Məhərrəmlik; محرمليک ) is a set of religious rituals observed by Shia Muslims during the month of Al-Muharram , the first month of the Islamic calendar . These annual rituals commemorate the death of Husayn ibn Ali , grandson of the Islamic prophet Muhammad and the third Shia imam . Husayn and his small retinue were slaughtered in the Battle of Karbala on 10 Al-Muharram 61 AH (680 CE ) against the army of the Umayyad caliph Yazid I ( r. 680–683 ). The battle followed Husayn's refusal to pledge his allegiance to Yazid, who is often portrayed by Muslim historians as impious and immoral. In Shia Islam, Karbala symbolizes the eternal struggle between good and evil, the pinnacle of self-sacrifice, and the ultimate sabotage of Muhammad's prophetic mission. Historically, the event served to crystallize the Shia community into a distinct sect and remains an integral part of their religious identity to date. Mourning for Karbala began with its female survivors, particularly Husayn's sister Zaynab , and evolved over time into distinct rituals that help define the Shia identity. Nowadays, most mourning rituals take place during the first ten days of Al-Muharram, culminating with processions in major Shia cities on the tenth day, known as Ashura . Often held in dedicated buildings, the main component of mourning ceremonies is the recitation of Karbala narratives intended to raise the sympathy of audience and move them to tears. Elegies and dirges are also chanted in such gatherings, as the participants strike their chests to share in the pain of Husayn and benefit from his intercession on the Day of Judgement . Extreme forms of self-flagellation are also sometimes practiced, often involving self-inflicted bloodshed. Such practices are highly controversial among the Shia, condemned by many Shia scholars, and outlawed in some Shia communities. Theatrical reenactment of Karbala narratives is a historically significant ritual found mostly in Iran .
