How did Sai Baba's life and practices make it impossible to label him as either Hindu or Muslim?

Sai Baba's life was a testament to his transcendence of religious labels. As Chapter 7 of the Shri Sai Satcharitra explains, his identity was a paradox. If he was called a Hindu, he looked like a Yavana (Muslim), but if called a Yavana, he possessed the noble marks of a Hindu. This ambiguity was physical as well; his ears were pierced like a Hindu, yet there was evidence of circumcision. He resided in a mosque, a traditionally Muslim place of worship, but within it, a sacred fire (Dhuni) burned day and night, and bells and conches were used, which are Hindu practices. Chapter 7 emphasizes that he was a 'holy' incarnation beyond these distinctions, as his conduct was always equal and impartial toward both communities, making it impossible to find even a trace of which caste he belonged to.
