Jama Masjid, Bhilai is one of the largest mosques in Chhattisgarh, India, with a capacity to accommodate more than 3000 worshippers at a time. It is the first Mosque to be built in the word "Ya Allah" in Arabic script. It took three years for the construction of the Mosque, which was completed in 1967. Before the Mosque's construction, the Muslims of Bhilai used to pray in their respective localities. They gathered only on Eid al-Fitr and Eid al-Adha to offer common prayer near Nehru house of Culture in sector-1, Bhilai. The Muslim executives of the Bhilai steel plant formed a committee and applied for its registration. It was registered as Bhilai Nagar Masjid Trust under the Madhya Pradesh public Trust act 1951. The Bhilai steel plant allotted a plot measuring 12000 square feet in sector-6 to this committee for the Mosque. The construction began in 1964 and was completed in 1967. The first Friday prayer was held in the new Mosque on 31 March 1967. The special design of the Mosque has created a history in the world of Islamic architecture through its monumental elevation, which forms an Arabic word Y? Allah.
