The Qurʼān calls the Torah and Gospel guidance and light, tells Muhammad to consult those who have been reading the prior scripture, and says the Prophet is written in the Torah and Gospel they have. Yet popular dawah claims the Bible was textually corrupted before Muhammad — which would make those Qurʼānic appeals incoherent. The Christian dilemma is: if the Bible is corrupted, why does the Qurʼān keep appealing to it? If the Qurʼān is right to appeal to it, then the Gospel that names Jesus as Lord predates Muhammad and stands.
What the Qurʼān actually says about previous scripture
The Qurʼān is not silent on the Bible. It treats the Torah and the Gospel as living, accessible scripture in Muhammad's lifetime.
- Q 5:46-47 says Allah gave Jesus the Gospel, containing guidance and light, and tells the people of the Gospel to judge by what Allah has revealed in it.
- Q 5:68 commands the People of the Book: You stand on nothing until you uphold the Torah and the Gospel and what was revealed to you from your Lord.
- Q 10:94 tells Muhammad: If you are in doubt about what We have revealed to you, ask those who have been reading the Book before you.
- Q 7:157 describes the Prophet as one whom they find written in the Torah and the Gospel they have.
- Q 5:43 asks why Jews come to Muhammad for judgment when the Torah is with them.
Classical tafsīr — al-Ṭabarī on Q 10:94, Ibn Kathīr on Q 5:68, al-Rāzī across multiple verses — repeatedly distinguishes taḥrīf al-maʿnā (distortion of meaning, by interpretation) from taḥrīf al-naṣṣ (corruption of the actual text), and most classical scholars favor the former for most cases.
The dilemma stated plainly
Take any modern dawah claim that the Bible was textually corrupted before Muhammad's lifetime and put it next to the Qurʼānic verses above. The two cannot stand together.
- Why call the Gospel guidance and light (Q 5:46) if the Gospel they have is corrupt?
- Why command the People of the Gospel to judge by it (Q 5:47) if the Gospel they have is corrupt?
- Why send the doubting prophet to those who read previous scripture (Q 10:94) if those scriptures were corrupt?
- Why describe Muhammad as already written in the Torah and Gospel they have (Q 7:157) if those scriptures had been altered?
A Christian friend can ask their Muslim friend: when did the corruption happen — before Muhammad, after Muhammad, or never? Each answer has costs.
What Bible Muhammad's contemporaries actually had
The Bible Muhammad's contemporaries read in the seventh century is the same Bible Christians read today. The four Gospels — Matthew, Mark, Luke, and John — were already universally received and copied in Greek, Syriac, Latin, Coptic, and Ethiopic.
We still have the manuscripts: Codex Sinaiticus (c. 350 AD) and Codex Vaticanus (c. 325 AD) preserve the New Testament from centuries before Muhammad. The Greek text of the Gospels these codices preserve is the same Gospel the Qurʼān commanded the People of the Gospel to judge by (Q 5:47).
In other words: the Bible Muhammad's contemporaries had is the Bible we still have — and it teaches the deity of Christ (John 1:1), the Trinity (Matthew 28:19), and the crucifixion of Jesus (1 Corinthians 15:3-8, John 19:30).
How Muslims usually answer the dilemma
Muslim friends typically answer the dilemma in one of two ways.
1. Distortion of meaning, not text (taḥrīf al-maʿnā)
This is the classical position. The text was not changed; the People of the Book misread it. On this view, the Qurʼān is not contradicting itself — it is rebuking misinterpretation, not affirming a corrupted book.
This position is honest and internally consistent. But it makes the popular slogan "the Bible is corrupted" misleading, because the New Testament's actual teaching on the deity of Christ, the Trinity, and the cross is not later corruption — it is what the Bible the Qurʼān points to actually says.
2. Wholesale textual corruption before Muhammad
This is the popular modern position. Christians changed the Bible centuries before Muhammad, the original Injīl was lost, and the Qurʼān corrects what was lost.
The difficulty is that the Qurʼān itself does not act as if this were the case. Q 5:46-48, Q 5:68, Q 10:94, and Q 7:157 only make sense if the scriptures Muhammad's contemporaries had were a reliable witness. If they were already corrupt, the Qurʼān has Allah commanding people to obey, judge by, and consult corrupt books. That is the heart of the dilemma.

How to think about it
- State the dilemma plainly. If the Bible is corrupt, the Qurʼān cannot rationally appeal to it as a witness. If the Qurʼān appeals to it, the Bible is not (textually) corrupt.
- Press for a date. When did the corruption happen — before Muhammad, after Muhammad, or never? Each answer has costs.
- Land on the gospel kindly. If the New Testament Muhammad's contemporaries had really is the New Testament we still read, then John 1, John 14, Matthew 28, and 1 Corinthians 15 are not late corruption. They are the Gospel Allah commanded the People of the Book to judge by — and they say Jesus is Lord.
Common objections
- But Q 2:79 says some of them write the book with their own hands.
Q 2:79 is read by classical commentators (al-Ṭabarī, Ibn Kathīr, al-Rāzī) as describing certain individuals, not the Bible as a whole. Even on the strongest reading, it does not warrant the modern claim that the entire Torah and Gospel had been falsified before Muhammad.
- Doesn't Q 3:78 prove they twisted scripture?
Q 3:78 describes a group twisting their tongues with the scripture so that the hearer thinks it is from the book when it is not. That is distortion of meaning in delivery, not textual corruption. Classical commentators take it that way.
- Maybe the original Injīl was a separate book Allah gave Jesus, lost before Muhammad.
The Qurʼān nowhere says the Injīl was lost. It says the People of the Gospel have it (Q 5:47). For more, see What is the Injīl?.
- Aren't there textual variants in the New Testament?
Yes — and Christian scholars are unusually transparent about them. But variants among 5,800+ Greek manuscripts let scholars reconstruct the text with very high confidence. Variants are not the same as wholesale corruption. See Are textual variants the same as corruption?.
