What Is Arbaeen?

The meaning of Arbaeen

In the Islamic calendar, Arbaeen falls on the 20th of Safar, forty days after Ashura. For Shia Muslims — and for many others who honour Imam Hussain’s stand for truth and justice — it is a day of remembrance and renewal. Every year, millions travel to Karbala in Iraq, many walking the roughly 80 km from Najaf in what has become one of the largest peaceful gatherings on earth.

Ashura and Karbala

On the 10th of Muharram in 61 AH (680 CE) — the day known as Ashura — Imam Hussain (AS) and 72 of his closest companions and family members were killed on the plains of Karbala by the forces of the Umayyad caliph Yazid ibn Muawiyah. Among the fallen were his brother and standard-bearer Abbas ibn Ali, his sons, and even his infant child Abdullah (Ali al-Asghar).

Hussain had refused to give his allegiance to a ruler he saw as destroying the essence of his grandfather’s message. Cut off from water for three days and vastly outnumbered, he chose death with dignity over life in humiliation.

A stand that still calls the conscience of humanity

Karbala is remembered not simply as a tragedy, but as a moral horizon: truth before comfort, dignity before submission, and sacrifice before silence. Imam Hussain declared that he rose “to seek reform in the nation of my grandfather — to enjoin what is good and forbid what is evil.” That declaration has echoed for fourteen centuries.

Karbala is not only a place in history. It is a question each generation must answer.

The captives and the first ziyarah

After the massacre, the women and children of the Prophet’s household — led by Sayyida Zaynab (SA) and the ailing Imam Ali ibn al-Hussain, Zayn al-Abidin (AS) — were taken captive and marched to Kufa and then Damascus. Their sermons in the courts of the oppressors turned a military defeat into a moral victory that could never be silenced.

Tradition holds that on the first Arbaeen, the family returned to Karbala to mourn at the graves, and that Jabir ibn Abdullah al-Ansari — an elderly companion of the Prophet — became one of the first pilgrims to visit the grave of Imam Hussain. Every pilgrim since walks in their footsteps.

Why pilgrims walk today

The walk from Najaf to Karbala is a moving act of remembrance: grief for what happened, love for the family of the Prophet, gratitude for the lesson, and a promise to carry it forward. Along the way, an unmatched culture of service flourishes — hundreds of mawakib (volunteer camps) feed, shelter, and care for pilgrims entirely for free.
