The Quran is the miraculous word of Allah and teaches absolute monotheism, affirming that Allah is a singular person without any divine plurality.

Muslims assert that the Quran is the uncreated speech of Allah, delivered through Muhammad, who is merely a passive recipient. However, a closer examination reveals that certain verses imply a plurality within the divine nature, contradicting the assertion of Allah's singularity. For instance, passages where Allah speaks in the first person and simultaneously refers to Himself as being sent or commanded by another entity suggest a multi-personal aspect to the divine. This is evident in verses where Allah claims to be a warner sent from Himself, which raises questions about the strict unitarianism that Islam promotes. Such grammatical and contextual nuances indicate that the Quran does not uphold the absolute monotheism it claims to represent, thus challenging the foundational beliefs of Islamic theology.
