"The name 'Allah' as God's name actually has roots that connect to the Bible itself. In Arabic, 'Allah' is the word for God, derived from 'Al-Ilah,' meaning 'The God'—the one, true deity. Now, Jesus (peace be upon him) spoke Aramaic, a sister language to Arabic, and in Aramaic, God is called 'Alaha' or 'Elah,' which sounds strikingly similar to 'Allah.' For example, in the Bible, when Jesus cries out on the cross, he says, 'Eli, Eli, lama sabachthani?' (Matthew 27:46), where 'Eli' is a form of 'Elah,' meaning 'My God.' These terms all trace back to the same Semitic root for God.
So, when the Qur'an calls God 'Allah,' it's not a new invention—it's consistent with the language of the prophets. The Bible doesn't use 'Trinity' or split God into three; it points to one God, and 'Allah' aligns with that ancient name. Islam preserves this truth, calling all people to worship the same One God—Allah—without partners or divisions, just as the prophets did. This linguistic link shows continuity, not contradiction, between the scriptures."
The word for God is "Elaha" (אלהא) in Aramaic. This comes from the word Elohim from Hebrew. Which Jesus also would have spoken. Elohim has a strong "El" sound at the beginning which would translate over into Elaha. Eloi Eloi is what was used by Jesus on the cross which was also closer to what the Aramaic would have been pronounced for God's name. This is nothing like the Quranic name for God. Elohim is directly translated into Theos in Greek. No where does anyone think Theos is the name of God, instead it is describing who he is. He is God. The name of God given to all mankind is Yahweh or Ehya (Exodus 3:14-16) [with Yahweh being the masculine plural of Ehya]. Which is used over 6,500 times in the bible. It was also transliterated into Greek with a similar sounding name (Iota-Alpha-Omega, Yah-Ooh, Greek didn't have a sound for W when the bible was written, the digamma). God said his name would be Yahweh for all generations (). This contradicts the Quran.
