Gugga or Jahar Pir is supposed to be the greatest of the snake-kings,with his kingdom somewhere near Ganganagar. Believed to be a Chauhan Rajput named Jahar originally, he later embraced Islam. Gugga is worshipped all over Haryana
. The 9th and the 15th of Bhadra, especially the former, is considered as Gugga Naumi
and dedicated to this Pir. Generally the 9th of any month and usually Mondays are regarded as his days. His shrine usually is a small one-room building with a minaret on each corner and a grave inside. Known as a 'mari' it is marked by a long bamboo with peacock plumes, a coconut, colored threads and some handpankhas with a blue flag on the top.
Gugga Fair in Himachal Pradesh and Gugga Dance of Haryana are also associated with Gugga.
