This is Helesa.

There is a legend widely told in Sinop about the emergence of the Helesa tradition. On a stormy day, a ship anchored in the port of Sinop. The ship has been in port for weeks and has run out of supplies. The captain of the ship began to think of ways to get out of this situation. The sailors went door-to-door with lanterns in their hands and began to sing hymns. And because of what they said, the people started paying the sailors. This tradition is still practiced in Sinop. During Ramadan and the holiday, young people go door-to-door with lanterns and say no. The money raised is donated to a charity.
