There is no way in hell that allah is a translation of the word Yahweh, no way. check out wikipedia -
"Yahweh" is not the Name of God, it is an approximation thereof based on the unvocalized Tetragrammaton YHVH. Since "Yahweh" appears nowhere in the Hebrew text of the Bible, the vocalization marks of Adonai were added later to remind the readers to refrain from attempting to pronounce The Name, which hasn't been pronounced since the destruction of the Second Temple.
It's a generic word meaning "the god".
Then it would be two words: the definite article al- and the word for "god" ilah.
Allah = Alaha = Elaha = Eloah. A generic title for a deity.
And on the Cross, when Jesus said Eloi Eloi Lama Sabachthani?, He was invoking a generic god as well? He certainly didn't say "Yahweh" or the complete 72-syllable name of God.
To this day I have yet to see the name Yahweh translated into Arabic.
Proper nouns, especially personal names, rarely require translation.
1) Allah didn't exist in written form before muhammed's time?
http://www.pantheon.org/articles/a/allah.html
This link says otherwise.
2) Where then is the muslim equivalent of the word Yahweh? If middle eastern Christians can do it, why not muslims? To this day, does ANYONE know what Yahweh translates into in arabic?
3) If that's the case then how do you explain allah's daughter's name "Allat" which literally means "The Goddess"? or his other daughter's name "Aluzzah" which means "The invincible"? allah means "the god". What muslims say now means nothing to me. It originally meant "the god", nothing more, nothing less.
4) Jesus didn't call out "Yahweh" because Jews (believing Jews) never used that word because it was considered so holy. Eloi means "my God", Jesus being Jewish was addressing it to Yahweh. When a Christian says "Thank God" we rigthly assume he's referring to the Judeo-Christian deity Yahweh. When a Hindu says "Thank God" we would rightly assume he's addressing a deity in his pantheon of Gods. God is not a proper name like : Jesus, Vishnu, Yahweh, Zeus, etc....
5) Find, show me how the word Yahweh is in any way connected with the word "allah".
