Could this be a warning to those who say Christians and Muslims worship the same God?

As I have written many times, I don't believe that Christians and Muslims follow the same God.  I think these verses could well be a warning to those who claim that we do follow the same God. 

Malachi 2:11-12(NKJV)

    Judah has dealt treacherously,     And an abomination has been committed in Israel and in Jerusalem,     For Judah has profaned     The Lord’S holy institution which He loves:     He has married the daughter of a foreign god.

    May the Lord cut off from the tents of Jacob     The man who does this, being awake and aware,     Yet who brings an offering to the Lord of hosts!
