What is the Baha’i Faith to the Naqshbandi Sufis? It came from the Naqshbandi Sufis?
The Bahai Faith is not part of Islam. It was created by a group in Iran who claimed their leader is a prophet after Sayyidina Muhammad (s). This is an invalid belief in the creed of Islam, which all Naqshbandis follow, for Naqshbandi belief is that Sayyidina Muhammad (s) is the Seal of Messengers, meaning the last and final in the succession of prophets and messengers since Sayyidina Adam (as), after whom there is no other prophet or messenger.
You are likely confusing the name of the founder of the Naqshbandi Tariqah, Shah Bahauddin Naqshband with the founder of the Bahai Faith. Next time you have such a question, try a basic encyclopedia first.
