In Varanasi, one of the world"s oldest living cities, Hindus and Muslims have prayed close to each other in a temple and a mosque that sit cheek by jowl. The heavily-guarded complex points to its uneasy history. The Gyanvapi mosque was allegedly built on the ruins of the Vishwanath temple, a grand 16th century Hindu shrine. The Hindus claim that the temple was partially destroyed in 1669 on the orders of Aurangzeb, the sixth Mughal emperor. Now the place is in the throes of a dispute which could stoke fresh tensions in Hindu-majority India, where Muslims are the largest religious minority. A bunch of Hindu petitioners have gone to a local court asking for access to pray at a shrine behind the mosque and other places within the complex. A controversial court order which allowed video-recorded survey of the mosque is said to have revealed a stone shaft that is the symbol of the Hindu deity Shiva, a claim that has been disputed by the mosque authorities. After this, a part of the mosque has been sealed by the court without giving the mosque authorities a chance to present their case. The dispute has now reached the Supreme Court, which said on Tuesday that the complex would be protected, and prayers will continue in the mosque. This has triggered fears of a re-run of a decades-long dispute involving the Babri Masjid, a 16th-Century mosque which was razed to the ground by Hindu mobs in the holy city of Ayodhya in 1992. The demolition of the mosque climaxed a six-year-long campaign by the Hindu nationalist Bharatiya Janata Party (BJP) — then in opposition — and sparked riots that killed nearly 2,000 people. In 2019, the Supreme Court ruled that the disputed site in Ayodhya should be given to Hindus who are now building a temple there. Muslims were given another plot to construct a mosque. A 1991 law called the Places of Worship Act disallows conversion of a place of worship and maintains its religious character as "it existed" on 15 August 1947, India"s Independence Day. Critics of the dispute in Varanasi say this is a defiance of the law. Asaduddin Owaisi, a prominent Muslim leader, says the "mosque exists and it will exist". A leader of the ruling BJP in Uttar Pradesh state, where Varanasi is located, believes nothing is set in stone. "The truth has come to light... We will welcome and follow orders of the court in the matter," Keshav Prasad Maurya, the deputy chief minister, says. But as Pratap Bhanu Mehta, a prominent commentator, observes: "Secularism will be deepened if it lets history be history, not make history the foundations of a secular ethic." And that the ongoing dispute in Varanasi can only end up opening "another communal front". Such concerns are premature, says Swapan Dasgupta, a right-leaning columnist. "There is, as yet, no demand for the removal of the mosque and the restoration of the previously existing state of affairs... Also the law does not allow any scope for the present religious character of a shrine to be modified," he wrote. "To that extent, the present tussle in Varanasi is aimed at securing greater elbow room for worshippers." Such assurances do not find many takers. Last year the Supreme Court accepted a petition challenging the Places of Worship law, which by itself could open a fresh fault line. "This campaign [in Varanasi] is just the beginning of a series of demands in respect to other places of worship on which there are [Hindu] claims," says Madan Lokur, a retired justice of India"s Supreme Court. — BBC
