I wanted to ask: If Muslims, Jews and Christians do worship the same God, then why do Muslims not worship Jesus as God as the Christians do and why don't Christians worship Allah as God as the Muslims do? Why don't the Jews worship Allah and Jesus as God as the Muslims and Christians do?
Just to keep this in perspective,
Why do non Gaudiya-s not worship Chaitanya as an incarnation of God? Why does that not make Gaudiya-s and Saivites into different religion.

Allah - Wikipedia
Christianity
The
Aramaic word for "God" in the language of
Assyrian Christians is
ʼĔlāhā, or
Alaha.
Arabic-speakers of all Abrahamic faiths, including Christians and Jews, use the word "Allah" to mean "God".[10] The Christian Arabs of today have no other word for "God" than "Allah".[29] (Even the Arabic-descended Maltese language of Malta, whose population is almost entirely Roman Catholic, uses Alla for "God".) Arab Christians, for example,
use the terms Allāh al-ab (الله الأب) for God the Father, Allāh al-ibn (الله الابن) for God the Son, and Allāh al-rūḥ al-quds (الله الروح القدس) for God the Holy Spirit. (See
God in Christianity for the Christian concept of God.)
Arab Christians have used two forms of invocations that were
affixed to the beginning of their written works. They adopted the Muslim
bismillāh, and also created their own
Trinitized bismillāh as early as the 8th century.
[30] The Muslim
bismillāh reads: "In the name of God, the Compassionate, the Merciful." The Trinitized
bismillāh reads: "In the name of Father and the Son and the Holy Spirit, One God." The
Syriac,
Latin and
Greek invocations do not have the words "One God" at the end. This addition was made to emphasize the
monotheistic aspect of Trinitarian belief and also to make it more palatable to Muslims.

According to
Marshall Hodgson, it seems that in the pre-Islamic times, some Arab Christians made pilgrimage to the
Kaaba, a pagan temple at that time, honoring Allah there as God the Creator.
[31]
Some archaeological excavation quests have led to the discovery of ancient pre-Islamic inscriptions and tombs made by Arab Christians in the ruins of a church at Umm el-Jimal in Northern Jordan, which contained references to Allah as the proper name of God, and some of the graves contained names such as "Abd Allah" which means "the servant/slave of Allah".
[32][33][34]
The name Allah can be found countless times in the reports and the lists of names of Christian martyrs in South Arabia, as reported by antique Syriac documents of the names of those martyrs from the era of the Himyarite and Aksumite kingdoms.[35][36]
A Christian leader named Abd Allah ibn Abu Bakr ibn Muhammad was martyred in Najran in 523, as he had worn a ring that said "Allah is my lord".
[35][37]
In an inscription of Christian martyrion dated back to 512, references to Allah can be found in both Arabic and Aramaic, which called him "Allah" and "Alaha", and the inscription starts with the statement "By the Help of Allah".
[35][38][39]
In pre-Islamic Gospels, the name used for God was "Allah", as evidenced by some discovered Arabic versions of the New Testament written by Arab Christians during the pre-Islamic era in Northern and Southern Arabia.[40][41][42]
Pre-Islamic Arab Christians have been reported to have raised the battle cry "
Ya La Ibad Allah" (O slaves of Allah) to invoke each other into battle.
[43]
"Allah" was also mentioned in pre-Islamic Christian poems by some
Ghassanid and
Tanukhid poets in
Syria and Northern
Arabia.

All of this also clearly shows that Muhammed knew what he was referring to (YHWH-Elohim) when he talked about Allah (and not a moon God).
