What is the proper noun for prophet?

There isn't a single, universally accepted proper noun for "prophet." The word itself is a noun, and while there are many famous prophets across different religions, they are typically identified by their individual names.

For example:

* Prophet Muhammad

* Prophet Moses

* Prophet Isaiah

* Prophet Zoroaster

You could also refer to a prophet by their title and then specify the religion:

* The Prophet of Islam (referring to Muhammad)

* The Prophet of Judaism (referring to Moses)

* The Prophet of Christianity (referring to Jesus, though he's often referred to as Christ or Messiah)

It's important to remember that these titles are not interchangeable, and using them correctly depends on the specific context and the religion in question.
