طسٓمٓ · تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ٱلْمُبِينِ
The question has been set out many times across the series (al-Baqara, Yāsīn, Ṣād, Qāf, al-Qalam) and is not repeated. Its summary: no certain knowledge about the meaning of these letters has been transmitted; the most honest position is to say that it is not known.
The only thing to be added here is a datum from the text: the letters ṭā-sīn-mīm occur in the Qurʾān at the head of two sūras — al-Shuʿarāʾ (26) and al-Qaṣaṣ (28). Sūrat al-Naml, which lies between them, begins with ṭā-sīn. Three consecutive sūras — 26, 27, 28 — thus open with the same family of letters, and all three recount the account of Moses. This is an overlap that can be counted.
The opening of al-Qaṣaṣ was treated in this commentary (al-Qaṣaṣ 28/1-6), and the same note was entered there.
تِلْكَ — feminine, the demonstrative pronoun used for the distant ("that", "there it is"). For the near one would say hādhihi.
A point of word order worth recording: the verses are in the hand of the one addressed, they are being recited — that is, they are near. Yet the distant demonstrative is used. The Arabic grammarians explain this usage as exaltation (taʿẓīm): the pronoun that points to the distant announces the elevated rank of what is pointed to.
The same opening is repeated in several sūras of the Qurʾān: tilka āyātu'l-kitābi'l-ḥakīm (Yūnus 10/1), tilka āyātu'l-kitābi'l-mubīn (Yūsuf 12/1), tilka āyātu'l-kitābi'l-ḥakīm (Luqmān 31/2 — treated in Luqmān). Al-Shuʿarāʾ uses the same attribute as Yūsuf: al-mubīn.
The root has been analysed in many places across the series (al-Zukhruf 43/2, al-Dukhān 44/2, Yāsīn) and is not repeated. The description given there: at the core of the root lies separation, the opening of a gap between two things; bayn — the space between. A thing becomes visible when it separates out.
And mubīn is an active participle, that is, not "made clear" but "making clear". The distinction matters here: the Book is not merely intelligible, it is what makes things intelligible.
| Verse | Construction | What it qualifies |
|---|---|---|
| 2 | al-kitābi'l-mubīn | The Book |
| 32 | thuʿbānun mubīn | What the staff turned into |
| 97 | ḍalālin mubīn | Error |
| 115 | nadhīrun mubīn | Noah himself |
| 195 | lisānin ʿarabiyyin mubīn | The language |
The sūra thus opens with the word for clarity and, in verse 195, ties that same word to language. This link will be treated in the section on 192-199.
