The Prophet Muhammad has been prophesied in many scriptures including the Bible, however some may not be aware of the ancient Persian scriptures of the ancient Persian faith of "Zoroastrianism", which is considered one of the oldest monothiestic religions before Judaism, Christianity, and Islam.

If you understand "Perenniel Philosophy" of Islam then you will understand that from an Islamic perspective, all the previous faiths were Islam by a different name. The message of "The One God" has always been the same from the first Prophet Adam to the last Prophet Muhammad (peace be upon them all).
