"Allah is indeed Tawhid—the embodiment of absolute oneness. In Islam, God's nature is defined by His singularity and uniqueness. He is not a composite being, not divided into parts, nor does He share His divinity with anyone or anything. The Qur'an declares, 'Allah is He, the One, the Self-Sufficient Master' (Surah Al-Ikhlas, 112:1-2), emphasizing that His oneness is intrinsic to who He is. This isn't just a concept we believe in; it's the reality of God Himself.
Contrast this with other beliefs, like the Trinity, which introduces a division—three persons within one God. That idea muddies the purity of divinity, suggesting multiplicity where there should be unity. But Allah, as Tawhid, is free from such complications. He's the Creator who stands alone, beyond comparison or limitation. This truth resonates deeply because it's simple and absolute: God is One, always has been, always will be. That's why Islam calls humanity to recognize Allah as He truly is—Tawhid in essence, unmatched and eternal."
Surah Al-Ikhlas (112:1-4)
Surah An-Nisa, 4:171
Surah Al-Ma'idah, 5:116
As Christians, we affirm wholeheartedly that God is absolutely one. The doctrine of the Trinity does not divide God—it explains the mystery of how the one divine Being exists eternally as Father, Son, and Holy Spirit. These are not three gods, but three distinct Persons who share the same divine essence.
When the Qur'an critiques the Trinity (Surah 4:171;, 5:116), it seems to address a misconception. Christianity has never taught that Mary or any created being is divine. The Nicene Creed (325 C.E.), formulated to defend the apostolic faith, declares clearly: "We believe in one God… and in one Lord Jesus Christ… being of one substance with the Father."
Far from compromising divine unity, the Trinity reveals its fullness. Scripture tells us that "God is love" (1 John 4:8). Love, by nature, involves relationship—and within the eternal oneness of God, that love has always existed between Father, Son, and Spirit.
Thus, the Trinity does not undermine Tawhid but unveils the inner depth of divine oneness: one God, eternally self-existent, self-giving, and relational in His very being.
