Tafsir is the explanation and interpretation of the Quran, the scholarly work of making clear what its verses mean, why they were revealed and how they apply. A tafsir is also the name for a written commentary, such as the famous Tafsir Ibn Kathir, that goes through the Quran verse by verse.
If a translation tells you what a verse says, tafsir helps you understand what it means. This guide explains the tafsir meaning, how scholars approach it, the major classical works, and why every verse on Quran Universe comes with Tafsir Ibn Kathir.
Key takeaways
- The word tafsir comes from an Arabic root meaning to explain, clarify or uncover.
- Classical scholars explain the Quran first by other verses of the Quran, then by the teachings of the Prophet Muhammad, then by the understanding of his companions and their students, and with the Arabic language.
- Tafsir Ibn Kathir, written by Ismail ibn Kathir (d. 1373 CE / 774 AH) in Damascus, is one of the most widely read Quran commentaries in the world and is available in English.
- Other major works include the tafsir of at-Tabari (d. 923 CE), Tafsir al-Qurtubi and the concise Tafsir al-Jalalayn.
- A translation conveys the meaning in another language, while a tafsir explains background, context, language and the views of scholars.
Tafsir meaning: where does the word come from?
The Arabic word tafsir comes from the root f-s-r, which carries the sense of uncovering or making something clear. A scholar who writes or teaches tafsir is called a mufassir.
The word appears in the Quran itself, in a verse about how God answers the objections of the Prophet's opponents. The phrase translated as "the best explanation" is ahsana tafsira in Arabic.
And they do not come to you with an argument except that We bring you the truth and the best explanation.
You may also hear the related word ta'wil. Early scholars often used the two words interchangeably for interpretation. Later, some used ta'wil for deeper meanings or for choosing between possible interpretations.
Why does the Quran need tafsir?
The Quran describes itself as clear, and many of its verses can be understood directly. But it was revealed over 23 years, in 7th-century Arabic, often in response to specific events. Some verses mention people and places without naming them. Others give a brief instruction whose details were explained by the Prophet Muhammad (peace be upon him).
The Quran states that explaining the revelation was part of the Prophet's role.
[We sent them] with clear proofs and written ordinances. And We revealed to you the message that you may make clear to the people what was sent down to them and that they might give thought.
Tafsir collects that explanation and adds the knowledge of language, history and law needed to read a verse in its proper context. For Muslims, it protects against taking a verse out of context. For non-Muslims, it is the best way to understand how Muslims themselves have read their scripture for fourteen centuries.
How do scholars explain the Quran?
Classical scholars, including Ibn Kathir in the introduction to his commentary, describe an order of sources for tafsir.
- The Quran explains the Quran. A brief phrase in one place is often explained in another.
- The Sunnah explains the Quran. The Prophet's sayings and example clarify many verses.
- The companions' understanding. They witnessed revelation and knew its context. Ibn Abbas, Abdullah ibn Mas'ud and Ubayy ibn Ka'b are among the most quoted.
- The successors (tabi'un). The students of the companions, such as Mujahid and Qatadah, passed on and developed this knowledge.
- The Arabic language. Grammar, vocabulary and the usage of the Arabs at the time of revelation.
Commentary built mainly on the first four sources is called tafsir bil-ma'thur, or transmitted tafsir. Commentary that relies more on scholarly reasoning is called tafsir bir-ra'y. Scholars accepted reasoned tafsir when it stays grounded in the transmitted sources and the language.
An example: the Quran explaining itself
In al-Fatihah, Muslims ask God to guide them to "the path of those upon whom You have bestowed favor." Who are these people? Another verse answers the question.
And whoever obeys Allah and the Messenger - those will be with the ones upon whom Allah has bestowed favor of the prophets, the steadfast affirmers of truth, the martyrs and the righteous. And excellent are those as companions.
An example: the Prophet explaining a verse
When the following verse was revealed, the companions were worried, since nobody is free of all wrongdoing. According to Sahih al-Bukhari, the Prophet explained that "injustice" here means associating partners with God, pointing to the words of Luqman in Quran 31:13.
They who believe and do not mix their belief with injustice - those will have security, and they are [rightly] guided.
Tafsir Ibn Kathir: the most widely read commentary
Tafsir Ibn Kathir, whose full title is Tafsir al-Quran al-Azim, was written by Imad ad-Din Ismail ibn Kathir. He was a scholar of hadith, history and law who lived in Damascus and died in 1373 CE (774 AH). He was a student of Ibn Taymiyyah and also wrote the famous history al-Bidaya wan-Nihaya.
His commentary follows the transmitted method closely. For each passage he typically:
- links it to other verses on the same topic
- quotes relevant hadith, often with notes on their reliability
- gives the explanations of the companions and successors
- warns about unreliable stories, especially reports taken from earlier scriptures without support
Tafsir Ibn Kathir in English
Tafsir Ibn Kathir is long in its original Arabic, so the most popular English edition is an abridged translation that keeps the core explanations and hadith while removing repetition and long chains of narration. It is widely used in mosques, study circles and homes around the English-speaking world.
Other major tafsir works
Ibn Kathir is one voice in a rich tradition. A few other works you will often hear about:
- At-Tabari's tafsir: Jami al-Bayan by Muhammad ibn Jarir at-Tabari (d. 923 CE / 310 AH) is one of the earliest complete commentaries. It gathers the reports of the companions and successors on each verse, and later commentators, including Ibn Kathir, drew on it heavily.
- Tafsir al-Qurtubi: al-Jami li-Ahkam al-Quran by al-Qurtubi of Cordoba (d. 1273 CE) is known for its focus on the legal rulings found in the Quran.
- Tafsir al-Jalalayn: written by Jalal ad-Din al-Mahalli and completed by his student Jalal ad-Din as-Suyuti, two scholars both named Jalal ad-Din, hence "the two Jalals." It is very concise and often used as a first commentary for students.
- Tafsir as-Sa'di: a modern, clear commentary by Abd ar-Rahman as-Sa'di (d. 1956), focused on lessons and guidance.
Scholars sometimes reach different conclusions on a verse. Good commentaries record these views respectfully, which shows the depth of the tradition rather than confusion.
Tafsir vs translation: what is the difference?
A translation puts the meaning of the Arabic into another language, as closely as possible. Every translation involves some interpretation, which is why Sahih International adds words in square brackets to make the meaning clear. Still, a translation is short by design.
A tafsir goes much further. It explains:
- the occasion of revelation (asbab an-nuzul), when known
- the meaning of difficult words and grammar
- how the verse connects to other verses and to hadith
- what the companions understood by it
- the rulings and lessons scholars derived from it
For example, the verses below make full sense once you know their background. According to Sahih al-Bukhari, Ibn Abbas explained that the Prophet used to move his lips quickly to memorize revelation while it was still being recited to him, and these verses told him not to worry.
Move not your tongue with it, [O Muhammad], to hasten with recitation of the Qur'an. Indeed, upon Us is its collection [in your heart] and [to make possible] its recitation. So when We have recited it [through Gabriel], then follow its recitation. Then upon Us is its clarification [to you].

Frequently asked questions
What is tafsir in simple words?
Tafsir is the explanation of the Quran. It tells you what a verse means, why it was revealed and how scholars have understood it. The word also refers to a book of Quran commentary, such as Tafsir Ibn Kathir.
What is the difference between tafsir and translation?
A translation puts the meaning of the Quran's Arabic into another language as closely as possible. A tafsir explains that meaning in detail, adding context, hadith, the views of the companions and the rulings scholars derived. Reading both together gives the clearest understanding.
Who was Ibn Kathir?
Ismail ibn Kathir was a scholar of tafsir, hadith and history who lived in Damascus and died in 1373 CE (774 AH). He was a student of Ibn Taymiyyah. His Quran commentary, Tafsir al-Quran al-Azim, is one of the most widely read in the world.
Is Tafsir Ibn Kathir available in English?
Yes. The most widely used English edition is an abridged translation that keeps Ibn Kathir's main explanations and hadith while shortening repetition. Quran Universe displays Tafsir Ibn Kathir in English for every verse of the Quran.
What is the best tafsir for beginners?
Many teachers recommend starting with a concise commentary, such as Tafsir al-Jalalayn or Tafsir as-Sa'di, or the English abridgement of Tafsir Ibn Kathir. Ibn Kathir is especially helpful because it explains verses through other verses and hadith. A teacher can also guide you on which commentary suits your level.
Can anyone do tafsir of the Quran?
Anyone can read and reflect on the Quran, and the Quran encourages this. Formal tafsir, however, requires deep knowledge of Arabic, hadith, the companions' views and Islamic law. That is why Muslims rely on qualified scholars when explaining what a verse means or what ruling it contains.
