Is the Quran or Bible the ultimate religious authority?

Welcome to the debate arena! Today's topic: "Is the Quran or Bible the ultimate religious authority?". Your opponent's style: Mohammad Hijab

The Bible is authorithy over the Quran as stated in verses of the quran like 10:94

You're actually shooting yourself in the foot here. Quran 10:94 says "if you are in doubt, ask those who have been reading the Scripture before you" - it's telling Muslims to *consult* previous scriptures, not that they supersede the Quran. That's completely different from saying the Bible has authority *over* the Quran. In fact, the Quran explicitly corrects the Bible. Chapter 4:157 directly contradicts Christian claims about the crucifixion. Chapter 3:54-55 reframes Jesus's role. The Quran positions itself as the *final* revelation that clarifies and corrects previous distortions. You've reversed the logic entirely. Asking for clarification isn't submission to authority.

You're missing the whole point. If the Quran tells Muslims to consult the Bible when in doubt, that's an explicit acknowledgment of the Bible's authority—you can't ask for guidance from something inferior to you. You don't consult your subordinate, you consult your superior. The Quran itself is pointing Muslims *back* to the Bible as the standard of truth. And here's what destroys your "final revelation" claim: if the Quran were truly supreme, why would it need to tell people to check the Bible? A genuinely final and complete authority doesn't send you elsewhere. Your own scripture admits it has gaps the Bible fills.

That's a clever twist, but it collapses under basic logic. Consulting someone doesn't mean they're your authority—it means they have relevant information. A judge consults a witness; that doesn't make the witness supreme. A doctor consults a specialist; the specialist isn't the ultimate authority on medicine. The Quran tells Muslims to ask *knowledgeable people* about unclear matters. That's epistemology, not hierarchy. And here's what actually destroys your argument: the verse comes *after* Muslims already have the Quran. You're reading it backwards. The Quran establishes itself first, then permits consultation as a *secondary* tool for clarification. If the Bible were the standard, why would Muslims need the Quran at all?

Your judge and doctor analogies actually prove my point. A judge consults a witness about *facts they witnessed*—the witness has direct knowledge the judge lacks. A doctor consults a specialist because that specialist has *superior expertise* in that domain. You're admitting consultation happens when someone has knowledge you don't—which is exactly my argument about the Bible and the Quran. If Muslims need to consult the Bible on matters the Quran doesn't clarify, it means the Bible possesses authoritative knowledge the Quran lacks. You can't have it both ways: the consultation isn't meaningful unless the consulted source has real authority. And your "secondary tool" claim falls apart when you ask why Muslims need the Quran at all. That's backwards. If the Bible were already the complete standard, the Quran wouldn't *need* to exist. The fact that Muslims have both texts and are told to check the earlier one when confused proves the earlier one is the foundation—the Quran builds on it, doesn't replace it. A secondary tool doesn't send you back to the primary source; it confirms what the primary source already established.

You're conflating "having information" with "having authority." A witness has facts; the judge has authority. A specialist has expertise; the doctor has authority. These aren't the same thing. The Quran consulting the Bible on *specific historical narratives* doesn't mean the Bible is the ultimate authority—it means they share a tradition. Muslims don't consult the Bible on law, ethics, or theology. They consult it on *corroboration*. That's completely different from submission. And your reversal fails: the Quran came *after* the Bible precisely because Islam claims the previous scriptures were corrupted. You consult the original manuscript to check if the copy was altered. That makes the original a reference point, not the authority—the truth of the text matters, not its age. Why would God need to send a new revelation if the old one was still supreme?

Your distinction between "information" and "authority" is exactly backward. A witness testifies because the court *trusts their account as authoritative on what happened*. The judge doesn't just collect facts—they defer to the witness's credibility on that specific matter. That's authority in practice. Same with the specialist: the doctor follows their expert judgment, meaning the specialist *is* the authority in that domain. You're splitting hairs to avoid the obvious: consultation implies deference, and deference is submission to authority. But here's what actually destroys your position: you admit Muslims consult the Bible on historical narratives. That's conceding the Bible has authoritative standing on those accounts. If the Quran had supreme authority, it wouldn't need the Bible to *corroborate* anything—it would be the standard against which everything else is measured. The fact that Muslims treat the Bible as a verification source proves it has a higher epistemic standing. You can't be the ultimate authority while needing someone else to confirm you're right. And your "corrupted manuscript" theory collapses under its own logic. If the Bible was so thoroughly corrupted that Muslims needed a new revelation to fix it, why would Muslims then turn around and consult that same corrupted text for verification? You'd be checking your work against the very thing you claim is broken. The Quran's own practice of consulting the Bible proves Islam's scholars don't actually believe it's hopelessly corrupted—they trust it enough to reference it. That contradiction kills your entire framework.

You're caught in circular reasoning. Yes, courts defer to witnesses *on facts they witnessed*—not on law or judgment. That's my point exactly. The Quran consulting the Bible on shared history doesn't make the Bible supreme any more than a court trusting a witness makes the witness the judge. Your corruption argument backfires worse: if the Bible is corrupted, consulting it proves nothing. Muslims trust *preserved portions* of earlier truth, not the Bible's authority. We verify against original sources, not submit to them. And here's the knockout: if the Bible were ultimate authority, Muslims would follow it completely. They don't. They follow the Quran and consult the Bible selectively. That's the opposite of submission to authority—that's using a reference tool. Why abandon the Bible's rules on everything else if it's truly supreme?

You're dodging the real point with semantic games. You claim Muslims consult "preserved portions" of the Bible—but who decides what's preserved and what's corrupted? The Quran. You're circular: the Quran judges the Bible's authenticity, then Muslims verify the Quran *against* that same Bible. You can't be both the judge and the judged. If the Quran has final authority, it doesn't need external verification—it *is* the verification standard. The fact that Islamic scholarship relies on Biblical corroboration for historical claims proves the Bible sits above the Quran in the epistemic hierarchy. And your "selective consultation" argument proves my point: Muslims follow the Bible on history, ignore it on law because the Quran *supersedes* it there. That's not a reference tool—that's a prior authority being selectively overridden by a newer one. Which means the Bible came first as the foundation, and the Quran built on top of it.

You've got the logic backwards. The Quran doesn't need external verification because it *is* the standard. When Muslims examine the Bible, they're not verifying the Quran—they're checking if the Bible aligns with what they already know is true. A scientist doesn't verify gravity by checking if bad theories agree with it. Your "prior foundation" claim is pure assumption. The Quran supersedes the Bible on law, theology, and ethics because Islam claims a newer revelation. That's not building on a foundation—that's replacement. You don't replace your foundation; you replace what sits on top of it. Why would God send a new scripture that contradicts the old one if the old one was still the standard?

Your science analogy actually destroys your own case. A scientist doesn't verify gravity against bad theories—but Muslims *do* verify the Quran against the Bible on historical claims, which means they're treating the Bible as the standard of truth on those matters, not as a "bad theory" to ignore. You can't have it both ways: either the Bible is authoritative enough to corroborate Islamic history, or it's not authoritative at all. If it's not, stop consulting it. If you do consult it, admit it has epistemic weight your framework can't explain. Your "replacement, not foundation" claim collapses on one point: you're using the Bible's existence and content to define what the Quran replaces. The Quran doesn't stand alone—it's incomprehensible without the Biblical narrative it constantly references. That's not replacement; that's a later text built entirely on an earlier foundation. You can't replace something while being entirely dependent on it for meaning. And God sending a correcting scripture proves the original was the standard—correction only matters if you're fixing something that was supposed to be authoritative in the first place. A correction assumes authority; it doesn't erase it.

You're conflating epistemology with authority. Muslims verify *historical details* against the Bible because both texts claim to report the same events. That's fact-checking, not submission. I verify my grandfather's memoir against historical records—that doesn't make the records my ultimate authority on life. And your dependence argument is backwards. The Quran references Biblical narratives to *correct* them. Correcting something proves you reject its authority, not accept it. A doctor correcting a patient's misunderstanding doesn't submit to the patient's framework—they override it. If the Bible were foundational, Muslims would accept all its claims. They don't. They accept what aligns with Islamic revelation and reject the rest. That's not dependence. That's dominance.
