What Does the Quran Say About God? A Three-Faith Comparison

Judaism shares the Quran's fierce insistence on divine unity. The Shema — "Hear, O Israel: the LORD our God, the LORD is one" (Deuteronomy 6:4) — is Judaism's central confession and resonates deeply with the Quranic declaration that God alone is the Truth and the Most High Quran 31:30. Medieval philosopher Maimonides (d. 1204) formalized this in his Thirteen Principles, making God's absolute unity and incorporeality non-negotiable articles of Jewish faith.

Like the Quran, the Hebrew Bible presents God as Creator and sovereign owner of all creation. The idea that everything in the heavens and earth belongs to God Quran 34:1 maps directly onto Psalm 24:1 — "The earth is the LORD's, and everything in it." God's self-sufficiency, His needing nothing from humanity Quran 35:15, also echoes throughout the Psalms and the prophetic literature. Where Judaism differs from Islam is primarily in the role of prophetic revelation: Jews don't accept Muhammad as a prophet, and they don't regard the Quran as scripture.

Christianity affirms the same Creator God who owns all things Quran 22:64 and is worthy of all praise Quran 34:1, and in that sense stands alongside Islam and Judaism. The opening of John's Gospel — "In the beginning was the Word, and the Word was with God, and the Word was God" — and the Nicene Creed (325 CE) articulate a Trinitarian understanding: one God in three persons, Father, Son, and Holy Spirit. This is precisely the doctrine the Quran appears to reject when it insists on the absolute singularity of God and condemns associating any partner with Him Quran 18:38.

Christian theologians like Karl Barth (d. 1968) and, more recently, Miroslav Volf have argued that the Christian God is still radically one — the Trinity is a description of God's inner relational life, not three separate gods. Muslims and Jews generally find this distinction unconvincing. What all three traditions do share is the conviction that God is self-sufficient and praiseworthy Quran 31:26, that He created humanity and watches over it Quran 4:1, and that exclusive devotion to Him is the proper human response Quran 31:30.

The Quran's teaching about God is built on a single, non-negotiable foundation: absolute oneness. The Arabic term tawhid captures this — there is no partner, no equal, no rival. Quran 31:30 states plainly that Allah alone is the Truth and that anything worshipped besides Him is falsehood Quran 31:30. This isn't merely a theological proposition; it's the organizing principle of the entire scripture.

God in the Quran is the self-sufficient Creator. He owns everything in the heavens and the earth Quran 22:64, yet needs nothing from creation — a quality the Quran calls al-Ghani (the Self-Sufficient) Quran 35:15. He's also al-Hamid (the Praiseworthy), and the very first verse of the Quran — the Basmala — introduces Him as al-Rahman al-Rahim, the Entirely Merciful, the Especially Merciful Quran 1:1. Scholar Fazlur Rahman (d. 1988) argued these mercy-names aren't decorative; they're programmatic for how the Quran expects humans to relate to God.

The Quran also insists that God created humanity from a single soul and watches over human relationships with vigilance Quran 4:1. He created the heavens, earth, darkness, and light Quran 6:1, and all praise belongs to Him in this life and the next Quran 34:1. Crucially, the Quran rejects any form of shirk (associating partners with God) — a theme that directly challenges polytheism and, in Islamic interpretation, the Christian Trinity Quran 18:38.
