Can you tell me the story of how Sai Baba protected his devotee Kashiram from robbers?

Certainly. Kashiram, a cloth seller, was once attacked by Bhil robbers. While he fought them to protect a small bundle, Sai Baba, who was miles away in Shirdi, became extremely agitated. As described in Chapter 0, Baba was shouting and swearing, which the people nearby recognized as his way of protecting a devotee in great danger. Despite being outnumbered, armed, and severely injured by an axe, Kashiram survived the encounter. The text notes, "what can the killer do against the Savior?" After the attack, Kashiram insisted on being taken to Shirdi, where he recovered under Baba's grace.
