The name Yehovah, pronounced Y'hoVAH in Hebrew, is derived from the verb HYH, meaning "to exist, to be". This meaning for His name is first revealed in scripture to Mosheh (Moses) in Sh'mot (Exodus) 3:14 where God says, "ehyeh asher ehyeh" which is translated "I am that I am", or better, "I shall be what I shall be". The meaning of His name indicates that He is the self-determining God who exists above all that there is (unlike the false-gods of the Egyptians).
Allah has no meaning, it just says "The God" yet the parsis in a same way refer to Ahura Mazda as the God, it's a title... and neither can the parsis be the same as islam either, since the parsis don't include the people of the book and are the ones who were persecuted by Muhammed. So they weren't practising islam when they prayed to their Allah. Their goes your theory as a proper noun for yahweh.
And i see God as a personal God, not as pantheistic being, Since God has revealed his nature i know what God is not. I know who He isn't. And i merely see Him as a peron -- regardless of Jesus diety (wich has nothing to do with it)--- based on His charateristicts i know what God sees as Good and what he sees as Evil. That defines who God is.
Basicilly The God defined in the bible isn't The God defined in the quran.
Two contradictionary revelations, of wich one is lying and will be exposed... i know wich one, when will you?
