Imam Hasan and Imam Hussain, the two sons of the Holy Imam Ali ibn Abi Talib and Hazrat Fatima, were respected and revered as the ‘Leaders of the Youths of Paradise’ as stated by the Holy Prophet.

The purpose of the march is for Shias to pay their respects to Imam Husain's holy shrine. Not all Shia carry on this tradition. It depends on how the individual was raised.
