In 1664 Emperor Aurangzeb summoned the seven-year-old Guru Har Krishan Ji to Delhi. Raja Jai Singh of Jaipur offered his bungalow, or bangla, for the Guru's stay. The Rani doubted so young a Guru and tested him: a maid sat on the throne in royal dress while the Rani sat among the maids. The Guru walked straight past the throne and sat beside the real Rani.
Delhi was then suffering from smallpox and cholera. Crowds came to the Guru, who gave them water from the bungalow's well, and the sickness began to recede. The Guru himself caught the disease and passed away on 30 March 1664. The Raja developed the well and gifted the bangla to the Sikhs; a small Gurudwara followed in 1783.
