Who is oracle?
As indicated by wiki, A prophet is an individual considered to give astute and adroit insight or prophetic forecasts, most remarkably including precognition of things to come, propelled by gods. Thusly, it is a type of divination.

And Prophet?
In religion, a prophet is an individual who is regarded as being in contact with a divine being and is said to speak on that entity's behalf, serving as an intermediary with humanity by delivering messages or teachings from the supernatural source to other people. The message that the prophet conveys is called a prophecy. In Islam, the Prophet Mohammed is said to be the Last of all the prophets.
Claims of prophethood have existed in many cultures throughout history, including Judaism, Christianity, Islam, in ancient Greek religion, Zoroastrianism, Manichaeism, and many others.

Here is the difference...
The Greeks looked to oracles, priests or priestesses who spoke of the Greek gods. The most important on their oracles resided and Delphi in northern central Greece. Oracles gave predictions or prophecies so they could be considered prophets.
The Hebrews called their prophets “navi” in the Old Testament. The New Testament, written in Greek called them prophets.
Prophet in Arabic called RASOOL. in Hindi or in sunskrit called "AUTAR" . Presently please go to a Prophet or a astrologer, who talks misrepresentation. They Can't tell about his future a fake subject. So here The prophets are the directly trustable and not to oracles.
