The clearest proof that Muhammad has replaced Allah in Islamic practical theology lies in Islam’s own soteriology, its doctrine of salvation.
Ask this: Why are Jews and Christians, both of whom worship the God of Abraham, classified as kuffar, infidels, under Islamic law?
Theologically, this makes no sense.
Jews affirm the oneness of God, reject idolatry, and follow a divine moral code.
So why are they damned in the Qur’an? Why are they cursed in the hadiths? Why are they to be fought, humiliated, and subdued?
The answer is simple: because they rejected Muhammad.
Not because they worshipped a false god, but because they refused to recognize Muhammad.
This reveals the heart of Islam: Islam is not about worshipping Allah, it is about allegiance to Muhammad.
Muhammad is not merely the messenger. He is the message.
Islam claims to be a monotheistic religion centered on submission to one transcendent deity. But in practice, the deity is transcendent, terrifying, and unknowable.
Muhammad is the functional center of Islam’s religious universe.
Rejecting Allah is almost abstract. But rejecting Muhammad is what actually makes someone an enemy, a target, an apostate, or an infidel.
His person becomes the dividing line between salvation and damnation.
This is why Muslims believe even the most devout Jew or morally upright Christian is destined for hell.
Because in Islam, moral clarity, monotheism, or good works, none of it counts unless you submit to Muhammad.
His name must be on your lips. His example must be your law. His honor must be defended with your blood.
The shahada, the Islamic declaration of faith, exposes this.
It doesn’t just say “There is no god but Allah.” That would be purely monotheistic. It must include: “and Muhammad is the messenger of Allah.”
Without that second part, you’re not a Muslim.
No biblical prophet ever demanded this.
Moses never said, “Believe in me or be damned.” Isaiah never taught that rejecting him personally would lead to eternal fire. John the Baptist pointed away from himself. Even Jesus said, “I do not seek my own glory.”
But Muhammad inserts himself at the center of cosmic judgment.
In that way, Islam is not just submission to God, it is submission to a man.
