The Hindu devotees of Imam Hussain: A case of cross-veneration
One of the most important events in early Muslim history was the battle of Karbala fought in 680 CE in which Imam Hussain, grandson of the Prophet through his daughter Fatima and her husband Imam Ali, was slaughtered along with a small band of disciples in a bloody battle against Yazid, a tyrant who had usurped the Muslim caliphate. The slaughter of Ali is one of the pivotal events that led to a divide between the 'mainstream' Sunni and Shi'ite communities, with the latter ascribing special importance to the family of Ali. This event occurred in the Islamic month of Muharram, and it is for this reason that this month is observed with great solemnity in many parts of the Muslim world.
What is particularly striking about the observances of the month of Muharram in India is the prominent participation of Hindus in the rituals. This has been a feature of popular religion for centuries in large parts of India, and continues even today, albeit on a smaller scale. In towns and villages all over the country, Hindus join Muslims in lamenting the death of Hussain, by sponsoring or taking part in lamentation rituals and tazia processions. In Lucknow, seat of the Shia nawabs of Awadh, prominent Hindu noblemen like Raja Tikait Rai and Raja Bilas Rai built Imambaras to house alams, standards representing the Karbala event. The non- Muslim tribal Lambadi community in Andhra Pradesh have their own genre of Muharram lamentation songs in Telugu. Among certain Hindu castes in Rajasthan, the Karbala battle is recounted by staging plays in which the death of Imam Hussain is enacted, after which the women of the village come out in a procession, crying and cursing Yazid for his cruelty. This custom is known as pitna dalna. In large parts of north India, Hindus believe that if barren women slip under an alam moving in a procession they will be blessed with a child.
