Who was Alli Mohammed, and what was his personal experience with Sai Baba's portrait as described in Chapter 41?

In Chapter 41, Alli Mohammed is the narrator of the story concerning the miraculous arrival of Sai Baba's portrait, an event he calls a 'clear Leela' or divine play. He recounts his experience of finding the picture in Mumbai. While observing a merchant selling various pictures of saints and holy men, one portrait of Sai Baba particularly captivated his heart. Since Sai was already his worshipped deity, he felt an immediate eagerness to have it. As the chapter details, he paid the price in cash, brought the portrait home, and hung it on the wall, deriving great joy from taking its darshan daily. This sets the stage for how this specific photo would later be gifted.
