Why was it so confusing for people to label Sai Baba as either Hindu or Muslim based on his life in the mosque?

According to Chapter 7, Sai Baba's life was a collection of paradoxes that defied simple religious labels, especially concerning his residence in a mosque. While living in a mosque would suggest he was Muslim, the activities within it were often associated with Hinduism. The text highlights that a sacred fire (Dhuni) burned there day and night. Furthermore, there was the grinding of grain, the ringing of bells, the blowing of conches, constant Bhajan (devotional singing), and ritual worship. These practices, as Chapter 7 explains, made people question how he could be a Muslim, reinforcing the idea that his incarnation was holy and beyond both religions.
