I also believe that the Abrahamic religions have one and the same God, but just have different names.
Surah 29:46:
"Do not argue with the People of the Book [the Jews and Christians] except in the kindest possible manner, save those of them who are oppressive, and say: “We believe in what was revealed to us and what was revealed to you; our God and your God are one and the same, and to Him do we submit ourselves."
"Elah" is a hebrew word for God and the Aramaic equivalent of it is "Alaha," taken from the Biblical Aramaic "Elaha" - and since Arabic is a sister language of the two languages - Allah is the Arabic cognate of the Aramaic word "Alaha." Given the prevalence of Judaism and Christianity in Arabia, the name "Alaha" would have been well-known and one would expect them to have Arabicized it by dropping the final "a" vowel.
Also, you'll see that the words "Elah," "Eloah," and "Alaha" appear in many places in the Tanakh (Jewish canon) such as in the books Ezra, Daniel, and Jeremiah when referring to the god of the Jews. These names are etymologically related to the name "Allah"

Etymology of the term Allah:
The term Allāh is derived from a contraction of the Arabic definite article al- "the" and ʾilāh "deity, god" to al-lāh meaning "the [sole] deity, God" (ὁ θεὸς μόνος, ho theos monos). Cognates of the name "Allāh" exist in other Semitic languages, including Hebrew and Aramaic. Biblical Hebrew mostly uses the plural form (but functional singular) Elohim. The corresponding Aramaic form is ʼĔlāhā אֱלָהָא in Biblical Aramaic and ʼAlâhâ ܐܰܠܳܗܳܐ in Syriac as used by the Assyrian Church, both meaning simply "God." - Wikipedia
During the course of my research, which is still ongoing, I've learned that the scriptures of Judaism have a lot more similarities with Islam than they do with Christianity.
Also, here is a Yemeni Jew who speaks Arabic, Hebrew, and Aramaic explaining how Allah is merely the Arabic form of a Hebrew word for God:
