What is the story behind the acquisition of Sai Baba's portrait as recounted by Alli Mohammed in Chapter 41?

In Chapter 41 of the Sai Satcharitra, Alli Mohammed shares the wonderful story of how he came to possess a portrait of Sai Baba. He explains that while walking on the streets of Mumbai, he saw a merchant selling various beautiful pictures of saints and holy men. As he perused the collection, a specific portrait of Sai Baba deeply appealed to his heart, standing out from all the others. Since Sai was already his worshipped deity, he felt a strong urge to have it. Alli Mohammed then purchased the picture, brought it home, and hung it on his wall, where he would joyfully take Darshan of it daily, reflecting his great love for Baba.
