How did Sai Baba demonstrate his omniscience when the Dhurandhar brothers visited Shirdi?

Sai Baba showed his divine foreknowledge in a remarkable way when the Dhurandhar brothers planned their visit to Shirdi. As detailed in Chapter 51, even before the brothers arrived in April 1912, Baba announced to the people in his court, "Today many of my court-people are going to come here." This greatly amazed the Dhurandhar brothers when they heard about it, especially since they had not informed anyone of their travel plans. This incident, where Baba knew of their arrival in advance, served as immediate proof of his extraordinary power, filling the brothers with wonder and deepening their faith as they ran to embrace his feet upon seeing him.
