According to Chapter 7, what specific physical attributes and yogic practices made it impossible to categorize Sai Baba's religious background?

Chapter 7 of the Shri Sai Satcharitra highlights several physical and mystical attributes that made it impossible to assign a specific religion to Sai Baba. The text points out the paradox that 'If called a Muslim, His ears were pierced; if called a Hindu, His circumcision was evident.' This combination of features, one traditionally Hindu and the other Muslim, confounded observers. Additionally, the chapter mentions his extraordinary yogic abilities, such as Khanda-yoga, where he could disjoint and reattach his limbs at will, and internal cleansing practices like Dhauti. These supernatural feats elevated him beyond ordinary human and religious classifications, showing his divine nature.
