According to Chapter 41, what is the story behind the acquisition of Sai Baba's portrait by Alli Mohammed?

The story of the portrait's acquisition is detailed in Chapter 41. Alli Mohammed recounts that one day, while wandering the streets of Mumbai, he came across a merchant selling various pictures of saints and holy men. As he looked through them, one particular portrait of Sai Baba deeply appealed to his heart, standing out as more attractive than all the others. Since Sai was already his worshipped deity, he became eager to have it, paid the price in cash, and took it home. He then hung the portrait on his wall and took daily Darshan with great joy and love for Baba. This account from Chapter 41 illustrates how Baba's leelas manifest in unexpected ways to fulfill devotees' desires.
