Words have meaning H20 and you make a hobby of looking past them.
Muslims generally believe that since Christians use Allah as a term to refer to the Biblical-God, that isn't enough proof that they believe in the same God. This actually prove that those Muslims have no clue about the difference between types of names that the Bible uses for God and do not know that only YHWH (Jehovah) is valid as God’s proper name. They probably never notice that YHWH (Jehovah), the personal name of God is never translated to Allah but either kept intact or rendered arrabb (the-Lord).
If you're into linguistics, this site has tons of information about the differences between Allah and Yehova.
