How did the villagers' view of Sai Baba change from thinking he was a madman to revering him?

Initially, the villagers of Shirdi considered Maharaj a mad Fakir due to his appearance and behavior. As described in Chapter 0, he wore torn clothes, sat in random places, and sometimes assumed a fierce form. However, a specific event dramatically shifted their perception. Maharaj was fond of lighting lamps in the Masjid, but one day the grocers refused to give him oil. Instead of forgoing his routine, he filled the lamps with water and lit them, and they miraculously burned all night. This astonishing event, mentioned in Chapter 0, made the villagers realize his divine nature. They were amazed, surrendered to him, and apologized for their previous insults and harassment.
