this is not true the name of ALLAH was revealed in the Quran and not from a pagan god..the Quran was revealed from god and no human has written it thus ALLAH is indeed the name of the god of the universe...the word "ALLAH" has the same meaning and the same name in Hebrew
read this:
The
etymology of the word
Allāh has been discussed extensively by classical Arab philologists.
[17] Grammarians of the
Basra school regarded is as either formed "spontaneously" (
murtajal) or as the definite form of
lāh (from the verbal root
lyh with the meaning of "lofty" or "hidden").
[17] Others held that it was borrowed from Syriac or Hebrew, but most considered it to be derived from a
contraction of the Arabic definite article
al- "the" and
ilāh "
deity, god" to
al-lāh meaning "the deity", or "the God".
[17] The majority of modern scholars subscribe to the latter theory, and view the loanword hypothesis with skepticism.
[18]
Cognates of the name "Allāh" exist in other
Semitic languages, including
Hebrew and
Aramaic.
[19] The corresponding
Aramaic form is
Elah (אלה), but its emphatic state is
Elaha (אלהא). It is written as ܐܠܗܐ (
ʼĔlāhā) in
Biblical Aramaic and ܐܲܠܵܗܵܐ (
ʼAlâhâ) in
Syriac as used by the
Assyrian Church, both meaning simply "God".
[20] Biblical Hebrew mostly uses the plural (but functional singular) form
Elohim (אלהים), but more rarely it also uses the singular form
Eloah (אלוהּ).
