Could you explain the backstory of the Sai portrait mentioned in the text and the reason for the long delay in sharing its history?

The source material from Chapter 41 recounts the history of a specific portrait of Sai Baba. The narrator and a priest named Ismu made a mutual and firm decision that this 'portrait of the powerful Sai' should be kept in the Maulana court. The narrator then personally presented the image. However, upon seeing that the recipient's meal was ready, he returned quickly without explaining the full story behind this action. He intended to share the long history at a more leisurely time, but as he states, while meaning to tell it 'today or tomorrow,' a full nine years passed. It was only after this long gap that an unexpected meeting finally provided the opportunity to remember and recount the past events.
