One of the other Muharram rituals in South Khorasan province is Bil Zani. This is one of the ancient traditions that are on Iran’s national heritage list. Birjand and Khusf cities are the main centers for the ritual.
The ritual of Bil Zani, also called Bil Gardani, is a reminder of the Banu Asad tribe. Three days after Ashura, the Banu Asad tribe reached Karbala and encountered the bodies of Imam Hussein (AS) companions. Then they dig the earth with their shovels and buried them. Bil Gardani in South Khorasan province is a symbol of the event.
