The story that Arbaeen remembers is not long, but it is heavy. Here it is, told plainly.
A demand, and a refusal
In the year 680 CE, the ruler Yazid demanded the allegiance of Imam Hussain. To give it would have meant endorsing a rule Hussain believed to be unjust. He refused, and left the city of Medina rather than be forced.
The journey
Invited by supporters in the city of Kufa, Hussain travelled towards Iraq with his family and a small band of companions — fewer than a hundred people, including women and children. On the plain of Karbala, an army of thousands, sent by the governor, blocked their path.
The siege
For several days the small group was surrounded. Then the water was cut off. In the desert heat, the children of Hussain’s camp went thirsty. Still, Hussain would not submit.
Ashura
On the tenth day of the month of Muharram — the day known as Ashura — Hussain and his companions were killed, one by one. He is said to have fallen last, in prayer. His half-brother al-Abbas, who tried to bring water to the children, was killed at the river’s edge. The women and remaining children were taken captive.
Why it endures
Karbala was a defeat, and yet it became one of history’s most enduring victories of conscience. By refusing to legitimise tyranny — even at the cost of his life and family — Hussain made his stand impossible to forget. Forty days later is the fortieth: Arbaeen.
