Kashkul

Kashkul (Persian: کشکول, Kashkūl, pronounced: kashkool) also referred to as the beggar's bowl, is a container carried by wandering Dervishes (belonging to the Sūfī sect of Islam) and used to collect money and other goods (sweets, gifts, etc.)

usually after a street session of poetry recitation, religious eulogies, advice or entertainment.

Together it indicates that all of the Dervish's worldly assets are in the container and therefore asking people to fill it through donations and gifts.

However, there are metal kashkul containers dated to around the 16th century at the time of the Iranian Safavid dynasty.

There are also references to the crescent-shaped kashkuls used to serve wine dated to around the 13th century.
