What primary story is introduced in Chapter 41 of the Sai Satcharitra, and who is the narrator of that specific account?

Chapter 41 introduces the miraculous story of how a physical photograph of Sai Baba arrived at the narrator's house at a predestined time. This chapter connects back to a previous event where Sai had promised in a dream, "On a Holi festival day, I am coming to your house for a meal today." The new account explains how this promise was fulfilled through the arrival of the photo. The specific story of the photo's origin and journey is narrated by a man named Alli Mohammed. As recounted in Chapter 41, this event is described as a humorous and clear divine play (Leela) that demonstrates Sai's power to fulfill the heartfelt desires of His devotees.
