Which specific Hindu practices did Sai Baba permit inside the mosque, challenging conventional religious boundaries?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba integrated numerous Hindu rituals into the mosque where he lived, demonstrating that it was a place for all. A sacred fire, or Dhuni, was kept burning day and night. The mosque also housed a grinding stone for grain, and the sounds of ringing bells and blowing conches, typical of Hindu temples, could be heard. Furthermore, the text mentions that offerings were made to the fire, bhajans were constantly sung, and ritual foot washing and worship occurred within its walls, all of which underscores Baba's transcendence of religious labels.
