How did Sai Baba's lifestyle and physical appearance create ambiguity about his religious identity as a Hindu or a Muslim?

According to Chapter 7, Sai Baba embodied a paradoxical identity that defied categorization as either Hindu or Muslim. If one considered him a Hindu, he looked like a Yavana (Muslim), yet if called a Muslim, he displayed the noble marks of a Hindu. This ambiguity was physical as well as practical; the text notes that his ears were pierced in the Hindu tradition, but it also mentions his circumcision, a Muslim practice. He resided in a mosque, a Muslim place of worship, further complicating any attempt to label him, making his incarnation, as the chapter states, holy and beyond both religions.
