Could you detail the miracle that caused the people of Shirdi to change their opinion of Sai Baba?

The event that changed the villagers' perception of Maharaj was a miracle involving lamps. According to Chapter 0, Maharaj was fond of lighting lamps in the Masjid and temples. He would get oil from local grocers, but one day they refused him, saying they had none. Unfazed, Maharaj put water in the lamps instead of oil and proceeded to light them. To the astonishment of the villagers, the lamps lit instantly and continued to burn all night. This incredible display caused the people to realize their mistake, surrender to Maharaj, and apologize for having insulted and harassed him.
