The festival commemorates the martyrdom of the prophet Mohammed's grandson- Hazrat Imam Hussein. It is celebrated with great fervour by the Muslims especially the Shia community. Tazias, glittering replicas of the Martyr's tomb, are carried in procession through the streets. The Tazias of Lucknow and Hyderabad are noted for their splendour. In places such as Lucknow, Delhi, Agra and Jaipur, grand scale processions are held. People beat their chest in mourning to the tune of beating drums and chants 'Ya Hussain'.
