According to Islamic belief, Allah is the most common word to represent God, and humble submission to his will, divine ordinances and commandments is the pivot of the Muslim faith. "He is the only God, creator of the universe, and the judge of humankind."
Allah, Arabic Allāh (“God”), the one and only God in Islam. Etymologically, the name Allah is probably a contraction of the Arabic al-Ilāh, “the God.” The name's origin can be traced to the earliest Semitic writings in which the word for god was il, el, or eloah, the latter two used in the Hebrew Bible (Old Testament).
Allah is the Arabic language word referring to "God", "the Lord" and, literally according to the Qur'an, to the "God of Abraham, Isaac and Jacob" in the Abrahamic religions. It does not mean "a god", but rather "the Only God", the Supreme Creator of the universe, and it is the main term for the deity in Islam.
Allah and the god of the Bible
Allah is usually thought to mean “the god” (al-ilah) in Arabic and is probably cognate with rather than derived from the Aramaic Alaha. All Muslims and most Christians acknowledge that they believe in the same god even though their understandings differ.
The transcendent nature of the Qur'an is simply a reflection of the transcendent nature of Allah himself. While Muslims of course believe that Allah is alive, he does not enter into the human realm as a living being, and so our knowledge of him is, at best, static, at worst, dead.
In Islam, Allah is not depicted as male or female — Allah has no gender. Yet Allah has traditionally been referred to, and imagined by many, as a man. Some Muslim women have begun to refer to Allah with feminine or gender neutral pronouns.
Indeed, Arabic-speaking Christians call God Allah. That may be jarring to modern day US Christians (who tend to think of Allah as “the god of Islam”), but the term existed in the Arabic world long before Islam arrived on the scene, and it is the Arabic equivalent of the Hebrew word Elohim.
Those who follow it are called Muslims (meaning "submitters to God"). Muslims view Christians to be People of the Book, and also regard them as kafirs (unbelievers) committing shirk (polytheism) because of the Trinity, and thus, contend that they must be dhimmis (religious taxpayers) under Sharia law.
Most mainstream Muslims would generally agree they worship the same God that Christians — or Jews — worship. Zeki Saritoprak, a professor of Islamic studies at John Carroll University in Cleveland, points out that in the Quran there's the Biblical story of Jacob asking his sons whom they'll worship after his death.
The Catholic Church since Vatican II has taught in different ways that Muslims and Christians do worship the same God.
As a religion, it is the world's third-largest, with over 1.2–1.35 billion followers, or 15–16% of the global population, known as Hindus. Hinduism has been called the world's oldest religion still practised, though some debate remains.
Aramaic is best known as the language Jesus spoke. It is a Semitic language originating in the middle Euphrates. In 800-600 BC it spread from there to Syria and Mesopotamia. The oldest preserved inscriptions are from this period and written in Old Aramaic.
Mainstream Bible translations in the language use Allah as the translation of Hebrew Elohim (translated in English Bibles as "God"). This goes back to early translation work by Francis Xavier in the 16th century.
The Quran repeatedly and firmly asserts God's absolute oneness, thus ruling out the possibility of another being sharing his sovereignty or nature. In Islam, the Holy Spirit is believed to be the Angel Gabriel.
Accordingly, Muslim scholars reject the Christian canonical Gospels, which they say are not the original teachings of Jesus and which they say have been corrupted over time.
The Afterlife
The Quran states that God will judge each individual by his or her deeds and that heaven awaits those who have lived righteously and hell those who have not. Belief in the afterlife is widespread among Muslims – majorities in all but one of the countries surveyed say they believe in heaven and in hell.
Christianity was born from within the Jewish tradition, and Islam developed from both Christianity and Judaism. While there have been differences among these religions, there was a rich cultural interchange between Jews, Christians, and Muslims that took place in Islamic Spain and other places over centuries.
Catholics worship the One and Only God, who is the Trinity (Father, Son, and Holy Spirit.) He is ONE God, in three divine Persons, and his name is YHWH or Yahweh. The second Person of this Trinity (the Son) came to earth and took on humanity. His name is Yeshua (meaning: “Yahweh Saves”).
Of course, Jesus was a Jew. He was born of a Jewish mother, in Galilee, a Jewish part of the world. All of his friends, associates, colleagues, disciples, all of them were Jews. He regularly worshipped in Jewish communal worship, what we call synagogues.
Dogs in Islam, as they are in Rabbinic Judaism, are conventionally thought of as ritually impure. This idea taps into a long tradition that considers even the mere sight of a dog during prayer to have the power to nullify a pious Muslim's supplications.
According to the Qur'an the use of hunting dogs is permitted, which is a reason the Maliki school draws a distinction between feral and domesticated dogs―since Muslims can eat game that has been caught in a domesticated dog's mouth, the saliva of a domesticated dog cannot be impure.
In Abrahamic religions, eating pig flesh is clearly forbidden by Jewish (kashrut), Islamic (halal) and Adventist (kosher animals) dietary laws. Although Christianity is also an Abrahamic religion, most of its adherents do not follow these aspects of Mosaic law and do consume its meat.
Muslims and Christians also believe that all humans are children of God. This means that both religions are monotheistic - meaning one God. Christians and Muslims believe that the word of their God was revealed to them through prophets, both believe that Jesus was a prophet who performed miracles!
God in Christianity is believed to be the eternal, supreme being who created and preserves all things. Christians believe in a monotheistic conception of God, which is both transcendent (wholly independent of, and removed from, the material universe) and immanent (involved in the material universe).
