Just to put matter correctly, Sikhism did not start with Guru Nanak. Up to the ninth Guru and part of the life of Guru Gobind Sing all were Hindus. if you check there names you will see that their name s are of Hindus. Guru Gobind sing was a Gobind Rai before he created the Sikh(Khalsa). Singh Word was originally with Rajputs and all raj puts are named Singh although they are Hindus. Guru Nanak was looked upon by both Hindus and Muslims alike. For Hindus He was a Guru and for Muslims He was a Peer. Muslims still pay homage to Guru nanaks dergah and also go to Nankana Sahib to pay their Homage and Respect. How Sikhism came to being 8is another subject. which is not discus able here it is complicated. There is no space.
