A Stunning Linguistic Law Discovered in the Qur’an — Without a Single Exception

Researchers have uncovered an extraordinary linguistic law in the Qur’an, one that applies to every single chapter without exception—a phenomenon unparalleled in the history of written texts.

While developing the most comprehensive statistical analysis program ever applied to the Qur’an, scholars discovered something remarkable:
each of the 114 chapters (surahs) of the Qur’an contains words that appear nowhere else in the entire book.

This rule applies to all 114 surahs, without a single exception.

🔹 Unique Words in Every Surah

For example, Surah Al-Fātiḥah contains two exclusive words:
“Iyyāka” (You alone) and “Nasta‘īn” (we seek help),
words found only in this chapter, as if reminding believers in every unit of prayer that true help can only be sought from God alone.

Surah Al-Baqarah contains 647 words unique to it (according to the original Qur’anic orthography), such as:
thread, cucumber, garlic, lentils, onions, and others.

Surah Āl-‘Imrān includes 289 exclusive words, such as:
ḥaṣūran, muḥarraran, nabtahil.

Even the shortest chapters at the end of the Qur’an follow the very same rule.

🔹 Striking Examples

• Surah Al-Ikhlāṣ
  It contains three words found nowhere else:
  As-Ṣamad, yalid, yūlad.
  These words appear exclusively in this chapter and in a negative form, emphasizing that God does not beget nor is He begotten, even though such terms could have appeared in other chapters discussing births—such as those of Jesus, Mary, Ishmael, Isaac, or John (peace be upon them all).
• The shortest chapter in the Qur’an, Surah Al-Kawthar, consisting of only ten words, contains five unique ones:
  We have given you, Al-Kawthar, sacrifice, your enemy, the cut-off.

🔹 Perfect Harmony Between Words and Meaning

What makes this law even more astonishing is that the exclusive words of each surah always reflect its core theme.

For example:

• Quraysh appears only in Surah Quraysh
• Al-Mā‘ūn only in Surah Al-Mā‘ūn
• Al-Falaq only in Surah Al-Falaq
• Al-‘Ādiyāt only in Surah Al-‘Ādiyāt
• Al-Humazah only in Surah Al-Humazah
• Al-Qadr only in Surah Al-Qadr
• At-Tīn only in Surah At-Tīn
• Al-Muṭaffifīn only in Surah Al-Muṭaffifīn
• Aṭ-Ṭāriq only in Surah Aṭ-Ṭāriq
• An-Nāzi‘āt only in Surah An-Nāzi‘āt
• Al-Mursalāt only in Surah Al-Mursalāt
• Al-Muddaththir only in Surah Al-Muddaththir
• At-Taghābun only in Surah At-Taghābun
• Adh-Dhāriyāt only in Surah Adh-Dhāriyāt
• Al-Aḥqāf only in Surah Al-Aḥqāf
• Al-Jāthiyah only in Surah Al-Jāthiyah
• An-Naḥl only in Surah An-Naḥl
• An-Naml only in Surah An-Naml
• Al-‘Ankabūt only in Surah Al-‘Ankabūt
• Al-Fīl only in Surah Al-Fīl
• Al-Kahf only in Surah Al-Kahf
• Ash-Shu‘arā’ only in Surah Ash-Shu‘arā’
• Luqmān only in Surah Luqmān
• Saba’ only in Surah Saba’
• Al-Mā’idah only in Surah Al-Mā’idah

And this pattern continues through every chapter of the Qur’an, whose exclusive words are almost always tied directly to their central message—often even to the chapter’s name itself.

🔹 A Clear and Powerful Proof

This astonishing linguistic law stands as a powerful proof that the Qur’an cannot be the product of human authorship.
No individual, no literary genius, and no collective effort could produce a text with such precision, consistency, and depth across its entirety.

As God declares in the Qur’an: “Say: If mankind and the jinn were to gather to produce the like of this Qur’an, they could not produce its like, even if they were to help one another.” (Surah Al-Isrā’, 17:88)

Another profound sign of the depth, coherence, and divine origin of the Qur’an.
