The science of Tajweed is one of the most precise Islamic sciences to which scholars have devoted great attention because it is directly related to the words of Allah Almighty, which were revealed in clear Arabic. Muslims have been commanded to recite the Quran properly as it was revealed. Among the most important topics in this science is the concept of mistakes in Quran recitation (Laḥn), due to its direct impact on the correctness of recitation and the preservation of meaning. Scholars have classified mistakes in Quran recitation into two main categories: Major Mistakes (Al-Laḥn Al-Jalī) and Minor Mistakes (Al-Laḥn Al-Khafī). Each category has its own definition, examples, effect on recitation, and legal ruling.

First: The Meaning of Laḥn (Mistake) in Language and Terminology

Linguistically, Laḥn means deviating from correctness. It is said that a person "made laḥn in his speech" when he made an error or departed from proper eloquent language.

In the terminology of Tajweed scholars, Laḥn refers to any mistake that occurs while reciting the Holy Quran, whether related to letters, vowel markings, characteristics of letters, or recitation rules, resulting in a defect in pronunciation or meaning.

Such mistakes may be obvious and easily recognized, or they may be subtle and only noticeable to specialists. This distinction led scholars to divide mistakes into major and minor categories.

Second: Definition of Al-Laḥn Al-Jalī (Major Mistake)

Al-Laḥn Al-Jalī is a clear and obvious mistake in recitation that alters the structure of a word, changes its meaning, or significantly changes the pronunciation of a letter or vowel.

It is called "major" or "obvious" because it can be recognized by almost anyone who hears it, whether knowledgeable in Tajweed or not.

This type of mistake is considered the most serious because it directly affects the Quranic text and may alter the intended meaning of a verse.

Forms of Al-Laḥn Al-Jalī

Major mistakes can appear in several ways, including:

Changing grammatical vowel markings

Such as replacing a ḍammah (u-sound) with a fatḥah (a-sound) or changing a kasrah (i-sound) into a ḍammah, potentially altering the meaning entirely.

Substituting one letter for another

Such as pronouncing one letter in place of another, for example replacing Ṣād (ص) with Sīn (س), or Dhāl (ذ) with Zāy (ز) in certain contexts.

Adding or omitting letters

Such as inserting a letter that does not exist in the word or dropping a letter that should be pronounced.

Changing the structure of a word

Such as altering its grammatical form or morphological pattern.

Examples of Al-Laḥn Al-Jalī
Reciting "Al-ḥamdu lillāh" (الحمدُ لله) by pronouncing the final letter with a kasrah instead of a ḍammah: "Al-ḥamdi lillāh".
Reciting "An‘amta" (أنعمتَ) with a ḍammah on the final letter, making it "An‘amtu", which changes the meaning from direct address to narration.
Replacing a letter in a word, such as pronouncing "Aṣ-Ṣirāṭ" as "As-Sirāṭ" in a manner that alters the correct pronunciation.
Omitting a hamzah where it should be pronounced.
Ruling on Al-Laḥn Al-Jalī

Scholars unanimously agree that intentionally committing a major mistake is prohibited because it constitutes an alteration of the words of Allah.

However, if it occurs unintentionally due to ignorance or lack of proper learning, the person is not sinful, provided they make an effort to learn and correct their recitation. Every Muslim is required to recite the Quran correctly to the best of their ability.

Third: Definition of Al-Laḥn Al-Khafī (Minor Mistake)

Al-Laḥn Al-Khafī is a subtle mistake in recitation that generally does not alter the meaning of the text and is usually not noticeable to ordinary listeners. It can only be recognized by those knowledgeable in Tajweed and the rules of Quranic recitation.

It is called "minor" or "hidden" because only specialists are able to detect it. A person may recite the Quran for many years without realizing they are making such mistakes if they have not studied Tajweed.

Forms of Al-Laḥn Al-Khafī

Among the most common forms of minor mistakes are:

Reducing or exaggerating Ghunnah (nasalization)

Such as failing to give the proper amount of Ghunnah in stressed Nūn and Mīm.

Shortening or neglecting Madd (elongation)

Such as shortening a natural Madd or failing to complete a required elongation.

Incorrect application of letter characteristics

Such as failing to properly pronounce heavy letters with Tafkhīm (emphasis) or incorrectly lightening them.

Neglecting the rules of Nūn Sākinah and Tanwīn

Such as failing to apply Iẓhār, Idghām, or other related rules correctly.

Failure to apply Qalqalah properly

Particularly in the letters of the phrase "Qutbu Jadd" (قطب جد) when they occur in a state of sukoon.

Examples of Al-Laḥn Al-Khafī
Pronouncing the word "Inna" (إنَّ) without a complete Ghunnah.
Shortening the natural Madd in words such as "Qāla" (قال) or "Fī" (في).
Failing to apply proper Tafkhīm to the letter Ṭā’ in a word like "Aṭ-Ṭarīq" (الطريق).
Weakening the Qalqalah in a word such as "Aḥad" (أحد).
Ruling on Al-Laḥn Al-Khafī

Minor mistakes do not carry the same ruling as major mistakes. According to the majority of scholars, they are considered disliked or a deficiency in the perfection of recitation because they indicate a lack of precision after learning.

As for someone who has not yet studied Tajweed, they are not held accountable for such mistakes, though they are encouraged to learn and improve their recitation.

Fourth: The Difference Between Major and Minor Mistakes

The differences between the two can be summarized as follows:

In Terms of Clarity

Major mistakes are obvious and noticeable to everyone, whereas minor mistakes are generally recognized only by specialists.

In Terms of Impact on Meaning

Major mistakes may alter the meaning of the Quranic text, while minor mistakes generally do not affect the meaning.

In Terms of Ruling

Major mistakes are prohibited when committed deliberately, whereas minor mistakes are considered a deficiency in the completeness and excellence of recitation.

In Terms of Severity

Major mistakes are more serious because they directly affect the Quranic text, while minor mistakes primarily affect the quality and precision of recitation.

Fifth: Causes of Recitation Mistakes

Some of the most common causes of both major and minor mistakes include:

Weak understanding of Tajweed rules.
Failure to learn directly from a qualified teacher.
Relying solely on personal reading without correction.
Reciting too quickly without proper attention.
Influence of local dialects that alter the articulation points of letters.
Sixth: Ways to Avoid Recitation Mistakes

To protect oneself from recitation mistakes, a Muslim should adopt a structured approach to learning, including:

Learning directly from a qualified and proficient teacher.
Studying the articulation points and characteristics of letters correctly.
Practicing slow recitation during the early stages of learning.
Listening regularly to skilled Quran reciters.
Continuously correcting mistakes and being willing to learn from others.
Seventh: The Impact of Mistakes on Recitation

Both major and minor mistakes affect recitation in several ways:

They may diminish the beauty and spiritual impact of recitation.
Major mistakes may alter the intended meaning of Quranic verses.
Minor mistakes indicate a lack of precision and mastery.
Persistent mistakes may weaken a person's connection with the Quran if they do not strive to improve.
Eighth: The Importance of Excellence in Quran Recitation

Perfecting Quran recitation is not merely about improving one's voice; it is a profound act of worship that reflects reverence for the words of Allah.

The righteous predecessors were meticulous in correcting even the smallest details of recitation because they understood that the Quran must be recited exactly as it was revealed, without alteration or distortion.

Moreover, excellence in recitation enhances reflection, humility, and attentiveness to the meanings of the verses, allowing the reader to develop a deeper connection with the Quran.

Conclusion

Studying major and minor mistakes in Quran recitation is one of the most important aspects of Tajweed because it helps Muslims appreciate the precision required in the recitation that Allah has commanded. Major mistakes are obvious errors that must be completely avoided, while minor mistakes are deficiencies in perfection that every reciter should strive to correct.

Whoever wishes to master the recitation of the Holy Quran should combine knowledge with practical application and remain committed to continuous learning. By doing so, their recitation will become free from errors, closer to the practice of the Prophet ﷺ, and a means of attaining the honor of correct recitation, the reward of reflection upon the Quran, and a higher status with Allah Almighty.
