Allah is another name for Jehovah.
Not exactly, Jehovah, or YHWH, is the specific name of God, or that specific class of beings when not standing alone all by itself, etc, and the other just means the generic term "God" in that language, etc...
Allah is not God's name, but only means just simply "God" in their language, etc, and because Muslims do not believe in a Trinity, they believe themselves to be referring to what they think is the "only true God", or God in and of the OT, etc, but that God has a specific name, etc, and that name is the four consonants YHWH/YHVH in our English language, etc, (they are still not sure which of those two it actually is due to how it (that name) is "sounded out" or pronounced, etc), but the word "Allah" has absolutely no resemblance of those four consonants sounds, etc, so is not God's name, etc, but is just simply "God", in their language, etc...
And like I said, they do not in any way believe in any kind of "Trinity", etc, so they think they are referring to the true God, or the number one always and forever highest God, etc, and think they are referring to God in and of the OT, etc, but I do not think they truly are, etc......
They follow Muhammad's teachings more than they do anything else, even the Bible, etc, and believe Muhammad's God/god to be the true God/god in reality, etc, and not really God in and of the OT, not really anyway...
And this is just my own personal opinion, but Muhammad had some strange ways and teachings, and many of them were very very "dark", etc, and I just don't believe his heart was pure enough to even know of the real true God truly or really, etc...
He was supposedly going off what he knew of the God in the first five books of the Bible, or the first five books of Moses, etc, but I really don't think he (Muhammad) truly knew Him/Them, etc...
Muhammad's life also I don't think reflects any of either the God/god, or gods, or True God very well either, etc...
He had "other ambitions" and "reasons" for creating the writings and books and philosophies that he did, during the day and time that he did, and for the situation he was in, etc, and in my opinion, hardly any of them were really very "pure" hardly at all either, in my opinion, etc...
I don't think Muhammad knew Him (God), or Them (any of the Three) in any way shape or form whatsoever, etc, and was "not even close to it", etc, or was very, very off, and very, very far away, from truly knowing not only the True God, but "any of them" really, any God/gods at all really, etc...
I think he created a god of his own making, etc, one very, very much just like himself, etc, and I think it's very very sad that he got all these people following him as if he were a God/god himself also, etc...
Cause I am fully convinced that he didn't know the True God, let alone any of the Three, etc, or even any of the Angels really at all either even, as I don't think he really knew "any of any of them", etc, or truly anything at all about that "class of beings" and their lives/existence, etc, and like I said, I think it's very, very sad, that his books, ways, philosophies, etc, all got turned into a "religion", etc, and that there are so very very many that follow him, and it is "him", etc, so very very blindly, etc...
Anyway...
God Bless!
