Cross-references (Mishkat Mutashābihāt)

The cross-reference data shipped on this site — the expandable "Related verses" panels on the Read page and the browser below — is the Mishkat Mutashābihāt corpus: documented verse-to-verse parallels, browsable without tafsir traversal. Coverage: 110 of 114 surahs (not yet covered: 104, 105, 106, 110).

● dataset. See Sources.

Conceptual lineage: the QurSim corpus (Sharaf and Atwell, LREC 2012) pioneered this approach, identifying 7,679 pairs of related verses ranked by relatedness. QurSim is cited here as a conceptual reference only — its canonical host is no longer accessible, and it is not the data this site ships.

The same Mishkat data, browsable a surah at a time: every verse in it that carries a documented parallel elsewhere in the Qur'an.

Sound and rhyme — the verse endings (fawāṣil)

Most surahs end their verses on recurring sound patterns — rhyme or assonance on the verse-final word (the fāṣila). Rhyme is one of the features scholarship reads structure from (Neuwirth's study of the Meccan surahs builds on it extensively). Pick a surah to see every verse ending, the rhyme families it groups into under two mechanical keys, where the ending pattern shifts, and any refrains (identical endings recurring three or more times).

~ Computed from the bundled morphology (scripts/build-rhyme-map.mjs): each verse-final word is reduced to an approximate pausal form (vowel marks stripped — which also drops the case endings, as pause does — final tā marbūṭa read as -ah), then keyed two ways: fine (last two letters) and coarse (final letter only). These are orthographic proxies, not a phonological transcription of recitation — endings that rhyme in recitation can split under the fine key (the coarse key exists to show exactly that tension). A shift in the key is a mechanical fact, not an asserted structural boundary.

Rhyme regularity across surahs

The panel above shows one surah at a time; this ranks all 114 by mean run length — the average number of consecutive verses that share a fine rhyme key before it changes (verse count ÷ (shift count + 1)). A high value means long, sustained runs on one ending (near-monorhyme); a low value means the ending pattern changes almost every verse.

Other documented features

• Fasilah: rhyming verse-end patterns, especially marked in early Meccan surahs.
• Ring composition: chiastic structures where openings and closings mirror. We tested one narrow, mechanical proxy for this — whether a surah's rarest content roots (occurring exactly twice) sit at matching distances from the surah's start and end more often than random placement would predict — across all 114 surahs (3,067 candidate root pairs, an exact per-surah-length null distribution, Benjamini-Hochberg correction at q<0.05). Zero pairs reached significance; the single closest candidate still fell short of the corrected threshold. This does not evaluate the literary scholarship cited below, which analyzes thematic and semantic parallels, not raw word position — it only shows this specific narrow proxy carries no corpus-level signal.
  Method and closest candidates
• Block-level mirror symmetry: a second, separate test asks the question the proxy above does not: whether whole sections of a surah (mechanically divided by where its vocabulary shifts most, not a scholar's reading) mirror each other in content. Four tests per surah (mirrored-section vocabulary overlap, first-section/ last-section overlap, recurring phrases bracketing both ends, verse-length palindrome), corrected jointly across every candidate in the corpus. Zero of 345 candidates reached significance. Like the proxy above, a survivor here would describe a mechanical property, never a literary finding, and is never attributed to a scholar.
  Method and closest candidates
• Parallelism: balanced clause structures.
• Qasam: oath openings (e.g., al-'Asr, al-Shams, al-Tin).
• The believers' vocative: ya ayyuha al-ladhina amanu ("O you who believe") opens 89 verses. This counts one specific formula — direct address in the Qur'an (khitab) is far broader, reaching even single pronouns ("It is You we worship"), and no single count could capture it.

• Boundary particles and lexical continuity: verses opening with idh ("when" / "recall"), idha ("when" / "if" — same clause-initial temporal family as idh, deliberately not extended to a sequencing word like thumma, "then", which marks continuation rather than a new temporal clause), or lamma ("when" / "once") — 350 occurrences combined. In 137 of those, the verse shares a content root with the verse immediately before it (e.g., 2:29 and 2:30 both use the root a-r-ḍ, "earth"). This records only where the marker and the shared root co-occur — it does not assert that the boundary is a thematic or rhetorical turning point; that judgment is an interpretive one this site does not make.
