Ziyarat Arba'een (Arabic: زیارة الأربعین) is an annual pilgrimage that takes place in the holy city of Karbala in Iraq.
It is the world's largest pilgrimage, reaching an estimated number of over 22 million pilgrims in 2023.
The pilgrimage seeks to honour the death of the third Shi'ite Imam, Husayn ibn Ali, who was a grandson of Muhammad.
[1] While the visitation of Husayn is not considered an Islamic obligation, like the Hajj (pilgrimage to Mecca), it plays an integral role in the religious life of Shia.
And Moses said to his brother Aaron, "Take my place among my people, do right [by them], and do not follow the way of the corrupters",[5] while the Hadith also reported that the earth mourns a death of believer for forty morning.
