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

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba's identity was intentionally ambiguous, making it impossible to definitively label him. For instance, if one called him a Hindu, he resided in a mosque. Conversely, if one called him a Muslim, a sacred fire (Dhuni) burned day and night in that same mosque, and Hindu rituals like ringing bells, blowing conches, and offering bhajans were common. The text also notes physical contradictions: he had pierced ears like a Hindu, but evidence of circumcision, a Muslim practice. This chapter concludes that Sai's incarnation was holy and beyond such distinctions, as he treated both communities with equal impartiality.
