AN APPROACHABLE GUIDE TO THE ARABIC OF GOD Allah and Ilah
Why Two Arabic Words for God Are Not a Contradiction
How Muslims, and Arabic-speaking Christians and Jews, use Allāh — and why ilāh does not cancel that name.
By Ali Hussain Amin - We have all heard the worn-out line that Allah is not the God worshiped by Jews and Christians. Some people go further and say that the very name Allah belongs to a pre-Islamic moon god. Both claims sound confident. Neither survives a close look at the Arabic itself, at how the Qur’an uses the two words for “god,” or at how Christians in the Middle East have prayed for centuries.
This article keeps the original point of a short note that many readers have already seen: Allāh and ilāh are not rivals. They do different jobs in the same language. Once that is clear, the supposed contradiction melts. What follows expands that note with classical language, Shi‘a sources wherever they speak directly to the names, and the plain evidence of the Arabic Bible.
People who do not read Arabic often treat the script as if every letter had one fixed shape, the way Latin letters do. Arabic is not built that way. Most letters change appearance depending on whether they stand alone, begin a word, sit in the middle, or end a word. The letter alif is a simple example. That is ordinary orthography, not a secret code. It does, however, explain why Allāh and ilāh can look more mysterious on a page than they are in speech.
The two words are related, but they are not interchangeable. Think of English “God” with a capital G and “god” with a small g. The first is how we name the One. The second is how we talk about deities in general, including false ones. Arabic draws a similar line, only more sharply.
Allāh is the proper name used for the one God. In ordinary Muslim use it has no plural and no feminine form. English usually renders it as God, with a capital G, or leaves it as Allah. Most linguists, and most Muslim scholars who accept a derivation at all, treat it as a contraction of al-ilāh, “the god,” that became a unique name through constant use.
WikiShia, the Shi‘a encyclopedia, puts the point cleanly: Allāh is “a proper name referring to the essence of God which possesses all perfect attributes.” The widely accepted view there is that the word comes from al-ilāh, from the root ʾ-l-h, “to worship.” So the sense is “the One who is worthy of worship.” The same page lists a feature that matters for this article: the name cannot be applied, literally or figuratively, to anyone or anything except God.
Allamah Sayyid Muhammad Husayn Tabataba’i, the great Shi‘a commentator of Tafsir al-Mizan, treats Allāh as a designated name for “the Essence of the Necessary Existent, which contains all of the attributes of perfection.” He notes that the word was already in use before the Qur’an. The Qur’an itself records that the Arabs of the Prophet’s time, when asked who created them, would answer “Allah” (Qur’an 43:87). They did not invent the name. They already used it for the Creator — and then, in Islamic teaching, they were called to stop pairing that Creator with other objects of worship.
A Shi‘a exposition published by the Shia Studies’ World Assembly says the same in slightly different words: Allah was originally al-ilāh; the middle hamzah dropped through frequent use. Al-ilāh is formed like an object-noun: as al-kitāb means “the written,” al-ilāh means al-ma’lūh, “the One who is worshiped,” or “the One about whom minds are bewildered.” It then became the proper name of God. The word is never used as an adjective for some other name. That is one of the grammatical signs that it is a proper name, not a generic label.
Ilāh is the generic word for a deity. It can mean the true God, or other gods, idols, or anything treated as an object of worship. Its plural is ālihah (“gods”). There is a feminine, ilāhah (“goddess”). In English it is usually translated god, lowercase, when the sense is “a deity in general” or “a false god.”
So ilāh is not “the word that never means Allah.” It is the category. Allāh is the specific name inside that category. Context tells you whether a given ilāh is the true One or not. The most famous sentence in Islam is built on exactly that distinction.
Read the table once, and the later arguments become easier. Allāh is to ilāh roughly what “God” is to “god.” Using both words in one sentence is not a slip. It is how Arabic says there is a category of worshiped things, and only one occupant of that category who is worthy of it.
lā ilāha illā Allāh
“There is no god but God”
“There is no deity except Allah”
The first word is the generic ilāh. The second is the proper name Allāh. A common and accurate paraphrase, used by both Sunni and Shi‘a teachers, is: there is no god worthy of worship except Allah. WikiShia calls this phrase tahlīl, “the most important phrase about the Unity of God in Islam,” and notes that the slogan of tawḥīd “exclusively involves this name.”
If Allāh and ilāh were two competing names for two different beings, the sentence would collapse. It works because they are not competing names. One is the class; the other is the Name. English can do the same thing: “There is no god but God.” No one who speaks English thinks that sentence proves the speaker worships two deities. It proves the opposite.
Shi‘a tradition gives the phrase a central place. In the Sermon of Fadak, Lady Fatimah al-Zahra’ (peace be upon her) says: “I bear witness that there is no god but Allah, alone, without partner — a word whose inner meaning is sincerity.” The wording is the same pair: no ilāh except Allāh. Shaykh al-Saduq (Ibn Babawayh, d. 381 AH / 991–92 CE), in his treatise on doctrine and in Kitāb al-Tawḥīd, states the Shi‘a belief as: there is no deity (ilāh) other than God; to God belongs creation and command. Imam Ja‘far al-Sadiq, as transmitted in the discussions gathered around al-Kafi and cited in later studies of the name, is reported to have connected the word Allāh with ilāh — not as two gods, but as name and root.
The Qur’an uses the same pair over and over. “Your God is One God; there is no god except Him” (2:163). “Allah — there is no god except Him. To Him belong the most beautiful names” (20:8). Surah al-Ikhlas, which Shi‘a and Sunni sources alike treat as a compressed creed, begins: “Say: He is Allah, One.” The pattern is consistent. Allāh names. Ilāh classifies. Tawḥīd is the claim that the class has one rightful member.
Arabic is a Semitic language, close to Hebrew and Aramaic, the languages of much of the Bible. The generic Arabic ilāh sits in the same family as Hebrew ʾelōah / ʾelōhīm and Aramaic / Syriac ʾelāh / ʾalāhā. English “God” is not a relative of those words. Allāh is. That is why Arabic-speaking Jews and Christians did not need a new vocabulary when they spoke about the God of Abraham. They already had the word.
This is a point about language, not a claim that every doctrine is the same. Muslims, Jews, and Christians describe God differently on questions such as the Trinity, incarnation, and the final prophet. Those disagreements are real. They are not settled, and they are not erased, by noticing that the Arabic noun is shared. What the shared noun does settle is a smaller, stubborn rumor: that Allah is, by the mere sound of the word, “a different god.” In Arabic it is the ordinary word.
This is the fact that surprises many English-speaking readers most. Arabic-speaking Christians — Copts in Egypt, Greek Orthodox and Melkites in the Levant, Maronites in Lebanon, Chaldeans and Assyrians who pray in Arabic, Palestinian and Jordanian Protestants — call God Allāh in church, at home, and in the Bible. They did not borrow the word from the Qur’an as a courtesy. They inherited it as their own language’s word for God. Pre-Islamic Arabian inscriptions already use Allah for the supreme God, and Arabic Christian use of the name is continuous from the early Islamic centuries to the present.
When Arabic-speaking Christians invoke the Trinity, a common formula is:
Bismi l-Āb wa-l-Ibn wa-r-Rūḥ al-Qudus, ilāhin wāḥidin, āmīn.
“In the name of the Father, and of the Son, and of the Holy Spirit, one God, Amen.”
Notice both words at work again: the three Persons are confessed as one God (ilāh wāḥid). In running prose and in Scripture, the name that fills the slot of English “God” is Allāh.
The Smith–Van Dyck Arabic Bible, completed in 1865 in Beirut and still the most widely used Protestant Arabic version — the King James of many Arab churches — renders John 3:16 this way:
“For God so loved the world, that He gave His only Son…”
The word printed where English has “God” is Allāh. The Jesuit Arabic Bible of the late nineteenth century does the same. So do earlier Arabic Gospel manuscripts. Islamic Awareness and several Christian translation studies have set the verses side by side: Genesis 1:1 in the Arabic Bible begins, in effect, “In the beginning Allah created the heavens and the earth.” That is not a Muslim interpolation. It is how Arabic says God.
To apply a blanket statement that Allāh does not mean God is an uninformed claim. A little reading of the book Arab Christians actually carry to church is enough to clear it up.
The moon-god theory is a modern polemic, popularized in the late twentieth century, especially by writings that tied the name Allah to a statue from Hazor in Palestine and to the moon deity Hubal. Professional historians of Arabia have not accepted the identification.
A few plain reasons are enough for a general reader. First, the Qur’an commands people not to bow to the sun or the moon, but to the One who created them (41:37). A scripture that forbids worship of the moon is a poor candidate for moon-god theology. Second, Hubal and Allah are distinguished in the early reports; if they had been the same deity, Hubal would likely have survived as an epithet of Allah, and it did not. Third, the Hazor figure used in popular slides is a Canaanite statue from far outside Mecca; specialists do not identify it with Allah. Fourth, Arabic-speaking Christians use the same name. A theory that makes “Allah” a pagan moon idol also insults those churches, as the Islamic studies scholar Joseph Lumbard has pointed out.
Pre-Islamic Arabs did use Allah for the high God, and they also worshiped other deities beside Him. Islamic tawḥīd is a protest against that pairing, not a baptism of the moon. Shi‘a and Sunni creed alike insist that nothing resembles God (42:11) and that the moon is a created sign, not a partner.
A reader who is new to Arabic only needs three habits.
1. When you see Allāh in a Muslim text, an Arabic Bible, or a church liturgy, read it as the proper name of God — the same slot English fills with “God.”
2. When you see ilāh or its plural, ask what the sentence is doing. It may mean the true God, or it may mean a false god. The grammar of “there is no ilāh except Allāh” is built for that question.
3. Do not treat a shared word as a completed theology. Muslims and Arabic-speaking Christians can use the same noun and still disagree about who God is. The noun does not invent that disagreement, and it does not erase it. It only shows that the disagreement is not about an accidental English translation.
Allāh is not a rival to the word “God.” In Arabic it is that word, raised to a proper name. Ilāh is the wider net. The two together let a speaker say, without contradiction, that the net should catch only One. Arabic-speaking Jews and Christians have long used the same proper name in their own scriptures and prayers. The claim that the name itself is foreign to the God of Abraham is not a careful conclusion. It is a rumor that cannot survive the page of an Arabic Bible or the opening line of the Islamic witness.
A little Arabic, a little history, and a little fairness are enough. The rest is older than the argument.

A note on method. This article explains words. It does not settle the larger theological debate among Muslims, Christians, and Jews about the nature of God. It only shows that the Arabic lexicon does not contain the contradiction some English polemics have placed there.
