"Massjid Shahid Ganj, in Lahore, was constructed as a mosque by one Falak Beg khan, in 1722. The Sikhs, however, claimed that the mosque had been built by demolishing a Gurdwara. Sometime around AD 1762 ,when Sikh power in the region was on the ascendant, they took possession of the building ... The land... became the site of a Sikh Gurdwara and the tomb of a Sikh leader, Bhai Taru Singh."
