Was Sai Baba a Hindu lord or a Muslim?
If he was a Hindu, then why did he distribute non-vegetarian food as prasada to people?
In the Charitra (biography) of Shri Sai Baba, nowhere his religion is mentioned.
He used to say "सबका मालिक एक |"
He was beyond any religion.
Devotees of all religions worship him.
Although Sai Baba is often connotated with Hinduism but he was never associated with a particular religion, nor his religion is explicitly mentioned anywhere in the records. He used to embrace every religion with equal respect. So it's hard to reach to any definite conclusion.
He taught us to see Ram in Ramzaan and Ali in Diwali. How could he differentiate? Destination is one paths are many. Truth is ONE, ways to realize are many, GOD is one but religion are many that lead us to HIM. He is that GOD. Those who had faith could see his Divinity and are even today seeing HIM in all HIS splendor blessing those who seek HIS refuge. He gave non-veg to check the faith of HIS Brahmin devotee. He later didnt allow HIM to eat once the brahmnin proved his faith.(Sathcharithra). He did it to both check faith and also to tell that HE has come for all.
