How did Sai Baba's actions and appearance create confusion about whether he was Hindu or Muslim?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba presented a profound paradox regarding his religious identity. If considered a Hindu, he looked like a Yavana (Muslim), yet if called a Yavana, he bore the noble marks of a Hindu. This ambiguity was central to his being. For instance, he resided in a mosque, a Muslim practice, but simultaneously maintained a constantly burning sacred fire (Dhuni) within it, a Hindu tradition. The text also points out the physical contradictions: if called a Muslim, his ears were pierced like a Hindu, and if called a Hindu, his circumcision was evident, suggesting he transcended these religious classifications entirely.
