During Iran's Chaharshanbe Suri, people traditionally jump over fire while reciting a wish for health.
Chaharshanbe Suri is an Iranian fire festival held on the eve of the last Wednesday before Nowruz, the Persian New Year. Participants light small bonfires and leap over them while saying a Persian phrase commonly translated as “Give me your redness, and take back my sickly pallor.” The words express a wish to exchange weakness or illness for the fire's vitality and warmth.
The festival combines pre-Islamic Iranian seasonal customs with later cultural practice. Fire is treated as a symbol of light, energy and purification, but the ritual is not simply a ceremony of worship. It is a popular communal observance involving families, food, fireworks and other regional customs.
Safety concerns have become significant in modern cities because fireworks and improvised explosives can cause injuries. The bonfire-jumping practice is therefore often organized in controlled settings, and the exact customs differ across Iran and Iranian communities abroad.
