Islamic Epistemic problem of Deception
Let me know your thoughts on this argument as I have deployed it a few times when someone asks why I'm not a muslim and it doesn't actually pit Christianity VS Islam as it's doing an internal epistemic critique of the Quran's own revelation.
Surah 4:157 denies the crucifixion: wa-lākin shubbiha lahum — "but it was made to appear so to them." On the Quran's own account, Allah caused the crucifixion to appear to occur when it did not. The predictable consequence — held across two millennia by hundreds of millions — is the central false belief of the world's largest religion.
The Muslim response typically appeals to Ezekiel 14:9 ("I the Lord have deceived that prophet") as a biblical parallel. It isn't one. The two cases are categorically different, and the difference matters because it determines whether divine deception is a contingent judicial act or a standing divine attribute.
The Argument
P1. Surah 4:157 attributes the appearance of the crucifixion directly to divine causation. Shubbiha lahum is a passive construction with Allah as the implicit agent.
P2. Ezekiel 14:9 is categorically different: it describes God hardening a prophet who has already compromised with idolaters, on a people who have already rejected the covenant. It is responsive, particular, and announced (cf. 1 Kings 22:19-23, where Micaiah openly tells Ahab the lying spirit is operating). It is judicial, not essential.
P3. The crucifixion deception in 4:157 has none of these features. The witnesses had not rejected the Quranic revelation — it didn't exist yet. The propagation extends to people across centuries with no access to correction. It is unannounced, non-judicial, and indiscriminate.
P4. Therefore Allah is, on the Quran's own testimony, a deceiver in the essential sense — one who produces appearances that create enduring false belief, where deception is a positive divine attribute rather than a contingent moral response.
Conclusion. A genuine inquirer has no non-circular epistemic warrant for trusting the Quran itself. If Allah causes appearances that produce false belief in matters of central religious importance, the inquirer cannot rule out that the Quran is itself such an appearance. The framework destroys its own foundation.
Objection 1: "It's a test, and the Quran is the correction."
It's a weak unfalsifiable claim and nothing would distinguish between God deceiving and a test from God.
Objection 2: "Allah judges people on the revelation they received, regardless of deception."
This concedes that Allah is a deceiver and gives no mechanism to discern truth from falsity.
