According to Chapter 41, who was Alli Mohammed and what was his role in the story of the portrait?

In Chapter 41 of the Sai Satcharitra, Alli Mohammed is the person who brings a portrait of Sai Baba to the narrator. His story provides the background for how the picture came into his possession. He explains that one day in Mumbai, he was wandering the streets and saw a merchant selling various pictures of saints. As he looked through them, one particular portrait of Sai Baba appealed to his heart more than any other. Since Sai was already his worshipped deity, he eagerly paid for the picture and took it home. As the chapter recounts, it was Alli Mohammed who then brought this cherished portrait to the narrator's house on Holi, arriving at the perfect time and fulfilling a divine promise.
