What is the story about the arrival of Sai Baba's portrait as told in Chapter 41?

Chapter 41 of the Sai Satcharitra recounts a fascinating story about how one of Sai Baba's physical portraits arrived unexpectedly. It connects back to a previous event where Baba appeared in a dream on a Holi festival day, promising to come for a meal. The chapter then details the 'miracle' of how a specific photo arrived at the perfect moment. A man named Alli Mohammed explains how he found this particular portrait while wandering in Mumbai. He saw a merchant selling pictures of various saints, and among them, a portrait of Sai Baba, whom he already revered, deeply appealed to him. As described in the chapter, he purchased it, took it home, and hung it on his wall, taking daily darshan with great love.
