The coming of Mohammed - Isaiah 21:7

Isaiah 21:7 (KJV) And he saw a chariot with a couple of horsemen, a chariot of asses, and a chariot of camels; and he hearkened diligently with much heed:

Some Muslims commentators (see two references below) contend that this is a prophecy referring to the coming of both Jesus Christ and Mohammed, with Mohammed coming after and therefore bringing a fuller revelation from God. However, this passage has nothing whatsoever do to with the coming of Jesus or Muhammad! Neither, according to the texts of Scripture, rode man-made "chariots." If Jesus was riding the asses and Mohammed the camels; who was riding the horses? This group doesn't fit anywhere in the Muslim philosophy. The context of the passage is a reference to the fall of Babylon. Isaiah 21:9 says, "Fallen, fallen is Babylon." The references to horsemen, donkeys, and camels, simply refer to the means by which the news of Babylon's fall was spread.
