زيارة الأربعين is an important religious observance for millions of Muslims, particularly among the Shia community. It occurs 40 days after the day of Ashura, which commemorates the martyrdom of Imam Hussein, the grandson of the Prophet Muhammad. During this time, pilgrims travel to the holy city of Karbala in Iraq to pay their respects at his shrine. The event symbolizes the values of sacrifice, justice, and standing against oppression. Many participants engage in acts of charity, communal prayers, and processions, reflecting their devotion and solidarity with the message of Imam Hussein. The gathering serves as a reminder of the historical significance of his struggle.
