Thiru Allah Puja
In 1740 AD the men of the Nawab took away the golden deity. At that time, the Nawab’s wife was afflicted with a serious illness.The physicians could do nothing about it. Then the Deity appeared in the dream of the temple priest and ordered him to go to Nawab’s palace and inform the Nawab that if the Deity was returned, his wife would be cured of illness.
Explaining the greatness of the Lord, the priest convinced the Nawab that the illness would be cured once the Deity was restored to its original place in the temple. The Nawab complied and acted accordingly. Nawab’s wife was cured. He was surprised that the illness of his wife had disappeared. The Nawab repented for his deeds and as a token of gratitude, he offered a pillow, crown, a golden plate and cup to the Lord.
A special worship was performed wherein a cap that is used to crown the Deity is fashioned like the Muslim head-dress. This was started by the Nawab and is still performed during the two annual festival and the paraphernalia offered by Nawab is used at the time of Seeveli puja every day. He also provided the fund for conducting annual puja, which is called Thiru Allah Pooja. The Thiru Allah mandapam within the temple is linked with this episode and is the place where 21-day Thiru Allah puja takes place even today.
