Though Muslims and Christians can describe Allah and Yahweh in similar ways at times, they are not the same god.
The Qur'an refers to Allah as the Lord of the Worlds. Unlike the biblical Yahweh (sometimes misread as Jehovah), he has no personal name, and his traditional 99 names are really epithets. These include the Creator, the King, the Almighty, and the All-Seer.
Yahweh, name for the God of the Israelites, representing the biblical pronunciation of “YHWH,” the Hebrew name revealed to Moses in the book of Exodus. The name YHWH, consisting of the sequence of consonants Yod, Heh, Waw, and Heh, is known as the tetragrammaton.
Mainstream Bible translations in the language use Allah as the translation of Hebrew Elohim (translated in English Bibles as "God").
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. Today, Arabic Bibles call God of Christianity Allah.
Towards the end of the Babylonian captivity, the very existence of foreign gods was denied, and Yahweh was proclaimed as the creator of the cosmos and the one true God of all the world, giving birth to Judaism, which has c. 14–15 million adherents today.
According to Amzallag, long before becoming the deity of the Israelites, Yahweh was a god of metallurgy in the ancient Canaanite pantheon, worshipped by smelters and metalworkers throughout the Levant, not just by the Hebrews. His theory is not exactly widely accepted, but has recently been gaining traction.
Jehovah (/dʒɪˈhoʊvə/) is a Latinization of the Hebrew יְהֹוָה Yəhōwā, one vocalization of the Tetragrammaton יהוה (YHWH), the proper name of the God of Israel in the Hebrew Bible/Old Testament. The Tetragrammaton יהוה is considered one of the seven names of God in Judaism and the personal name of God in Christianity.
And yet, despite the manifest differences in how they practise their religions, Jews, Christians and Muslims all worship the same God. The founder of Islam, Muhammad, saw himself as the last in a line of prophets that reached back through Jesus to Moses, beyond him to Abraham and as far back as Noah.
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).
Yahweh is the name of the state god of the ancient Kingdom of Israel and, later, the Kingdom of Judah. His name is composed of four Hebrew consonants (YHWH, known as the Tetragrammaton) which the prophet Moses is said to have revealed to his people.
The Nation of Yahweh is predominantly a Black Hebrew Israelite religious movement which was founded in 1979 in Miami by Hulon Mitchell Jr., who went by the name Yahweh ben Yahweh. (Yahweh is the proper name of the Abrahamic god, so Yahweh ben Yahweh literally means "God, son of God".)
In this case, the meaning of God's name Yahweh is explained with the sound-alike ehyeh, a Hebrew being verb usually translated, “I am” or “I will be.” But the usage of being verbs such as hayah/ehyeh in Hebrew differs slightly but significantly from the way being verbs are used in most Western languages.
"Yahweh" is the Hebrew word for the self-revealed name of the God of the Old Testament. It comes from the Hebrew verb "To be." At its core, "Yahweh" means "To be." The English Bible translates it as "LORD," which distinguishes it from "Lord" (which is translated as "master").
God in Judaism has been conceived in a variety of ways. Traditionally, Judaism holds that Yahweh, the God of Abraham, Isaac, and Jacob and the national god of the Israelites, delivered the Israelites from slavery in Egypt, and gave them the Law of Moses at Mount Sinai as described in the Torah.
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.
Allāh. Translation. "The God" 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.
Yahweh is the principal name in the Old Testament by which God reveals himself and is the most sacred, distinctive and incommunicable name of God.
Jesus' name in Hebrew was “Yeshua” which translates to English as Joshua.
The 100th name of Allah is “ana” (me/I am). The learned scholar and mystic Mansur Al-Hallaj was put to death in the 9th century for revealing this secret.
The Catholic Church since Vatican II has taught in different ways that Muslims and Christians do worship the same God.
Christianity developed out of Second Temple Judaism in the 1st century CE. It is founded on the life, teachings, death, and resurrection of Jesus Christ, and those who follow it are called Christians. Islam developed in the 7th century CE.
