How did Sai Baba's actions and appearance make it impossible to classify him as either Hindu or Muslim?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba's life was a paradox that defied religious categorization. If he was called 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. The text notes that while he resided in a mosque, a practice associated with Islam, he maintained a perpetually burning sacred fire (Dhuni) and allowed the ringing of bells and blowing of conches, which are Hindu customs. Furthermore, if one considered him a Hindu, his circumcision was evident; if one called him a Muslim, his ears were pierced, a Hindu tradition. The chapter concludes that he was a holy incarnation beyond both classifications, as his conduct was always equal and impartial.
