Tawrat and Injil — The Torah and Gospel in Islamic Theology: Revelation, Corruption, and the Quran's Relationship to Previous Scripture

The Positive Islamic Affirmation — Previous Scriptures Were Real

The Quran explicitly confirms the divine origin of previous revelations:

“Indeed, We sent down the Torah, in which was guidance and light.” (5:44)

“And We sent, following in their footsteps, Jesus, the son of Mary, confirming that which came before him in the Torah; and We gave him the Gospel, in which was guidance and light.” (5:46)

“Say: We have believed in Allah and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them.” (3:84)

This is the foundational Islamic position: the original Tawrat and Injil were genuine revelations from Allah.

What Is Tahrif — The Types of Corruption

Tahrif al-lafzi (textual corruption): The actual words of the original revelation were changed — additions, deletions, or substitutions. The scholarly debate among Muslim scholars: was the original text corrupted, or were later translations and manuscripts corrupted?

Tahrif al-ma’nawi (interpretive corruption): The words were preserved but their meaning was distorted through misinterpretation, mistranslation, or contextual removal. Many contemporary Muslim scholars favor this form as the primary tahrif — arguing that human interpretation overlaid and distorted divine meaning without necessarily altering every word.

The historical argument for corruption: Islam points to:

1. Manuscripts vary across centuries and communities
2. The Nicene Council (325 CE) made doctrinal decisions about what counted as scripture
3. Books attributed to Moses, David, and Solomon show clear internal evidence of later editing
4. The description of Muhammad’s prophethood that the Quran says exists in the Torah and Gospel (7:157) is not found in current versions — suggesting either deletion or interpretive concealment

The Quran as Criterion (Muhaymin)

“And We have revealed to you the Book in truth, confirming that which preceded it of the Scripture and as a criterion (muhaymin) over it.” (5:48)

Muhaymin (guardian, criterion, judge) means the Quran serves as the standard by which the preserved elements of previous scriptures are to be assessed. Where current Torah or Gospel content aligns with the Quran, it represents preserved divine content; where it contradicts, the Quran is authoritative.

The Ismaili Esoteric Reading

In Ismaili ta’wil, the Tawrat, Injil, and the Quran are successive revelations carrying both a zahir (outward law) and a batin (esoteric wisdom). The corruption (tahrif) of previous scriptures occurred partly because the esoteric interpretation (ta’wil) became inaccessible after the prophets who carried it departed and their successors were unable to transmit the batin authentically. The Quran’s preservation is guaranteed by Allah (“Indeed, it is We who sent down the Reminder, and indeed, it is We who are its Guardian” — 15:9), and the Imam’s presence ensures the batin dimension continues to be accessible.
