What is the primary story introduced in Chapter 41 of the Sai Satcharitra, and how does it connect to a previous event?

Chapter 41 of the Sai Satcharitra introduces the miraculous story of how a physical portrait of Sai Baba arrived unexpectedly. The chapter connects this event to a previous story where the narrator had a dream in which Sai promised, "On a Holi festival day, I am coming to your house for a meal today." The arrival of the photo is presented as the fulfillment of this dream. As detailed in this chapter, a man named Alli Mohammed brought the portrait at the exact peak moment when the narrator was about to sit for lunch on that very Holi day, delighting him and serving as a clear example of Sai's divine play, or Leela.
