The Definition and Categories of Tafsir

Ibn Taymiyyah's treatise on the principles of Quranic interpretation stands as one of the most authoritative classical discussions of tafsir methodology. Written by one of the most rigorous intellects of the eighth Islamic century, it establishes the epistemological framework within which legitimate Quranic interpretation must operate — a framework grounded in revealed sources and classical Arabic, resistant to both arbitrary private interpretation and the importation of alien frameworks.

The word 'tafsir' derives from the Arabic root meaning to uncover or explain what is obscure. As a technical discipline, tafsir is the science of explaining the meanings of the Quran: identifying the referents of its pronouns, explaining the significance of its vocabulary, resolving apparent contradictions between verses, understanding the relationship between general and specific passages, and applying its commands and prohibitions. It is arguably the most important of the Islamic sciences, since all other religious knowledge ultimately depends on sound understanding of the revealed text.

Ibn Taymiyyah identifies several categories of tafsir distinguished by their source and methodology. Tafsir bil-ma'thur (interpretation by transmitted reports) includes interpretation of the Quran by the Quran itself, interpretation by the Sunnah of the Prophet, interpretation by the statements of the Companions, and interpretation by the statements of the Tabi'un. This category represents the most authoritative form of tafsir because it grounds Quranic meaning in sources directly connected to the revelation.

Tafsir bil-ra'y (interpretation by opinion or reasoning) is of two types. The praiseworthy type is interpretation based on sound linguistic knowledge of classical Arabic and familiarity with the full Quranic context, conducted by a qualified scholar whose reasoning is constrained by the transmitted sources. The blameworthy type is interpretation based purely on personal opinion, divorced from the transmitted tradition and from sound Arabic usage — a form of speaking about Allah without knowledge, which the Quran explicitly prohibits.

Ibn Taymiyyah also introduces the category of tafsir bil-isharah (interpretive allusion), associated with Sufi exegetes who derive spiritual meanings from Quranic verses beyond their apparent sense. He subjects this category to careful evaluation: an interpretive allusion that does not contradict the apparent meaning of the verse, is supported by evidence from elsewhere in the Quran or Sunnah, and is not presented as the exclusive or primary meaning of the verse may be acceptable. But an interpretation that contradicts the plain meaning of the text, is supported by no external evidence, and is claimed as the verse's true hidden meaning is a form of innovation condemned by the scholarly tradition.

This opening chapter establishes the evaluative framework that readers need to assess any tafsir they encounter, whether classical or contemporary. Ibn Taymiyyah's categories remain the standard reference points in traditional Islamic scholarly assessment of interpretive methodology.
