Step 3 — Understand
Classical Meaning & Context
Toggle open Mufradat al-Quran for al-Raghib al-Isfahani's classical definition of the root — the standard Quranic lexicon for over 900 years.

Linguistic Distinctions shows how near-synonyms differ. Arabic has multiple words for concepts like "knowledge" or "fear" — each root carries a distinct shade of meaning.

Step 4 — Connect
Families & Connected Verses
The Semantic Family panel shows which thematic group this root belongs to — 39 families like mercy, justice, prayer, trade, eschatology.

Connected Verses lists every ayah in the Quran containing this root, so you can trace how a concept threads through different surahs.

What the Data Reveals

When you connect 6,236 Quran verses to 112,000+ hadiths through 1,590 shared Arabic roots, patterns emerge that no manual reading could surface.

Meccan Compression

Meccan surahs use fewer, more concentrated roots — the same core vocabulary repeated with intensity. Medinan surahs expand into a broader vocabulary covering law, governance, and social contracts. The Quran's own linguistic structure shifts as its audience and purpose shift.

Provision Connects to Action

The thematic family for provision (rizq) overlaps most with body (hands, feet), travel, worship, and speech. The hadith corpus links sustenance to physical effort, movement, devotion, and what you say — not to passive waiting.

Book Fingerprints

Each hadith collection has a thematic signature. Musannaf Ibn Abi Shaybah is heavy on fighting, inheritance, and wealth (fiqh rulings). Malik's Muwatta concentrates on purification and worship (Madinan practice). Bukhari is distinctive in knowledge and eschatology. The data confirms what scholars have said for centuries about each compiler's editorial intent.

Quran–Hadith Root Correlation

Roots that are frequent in the Quran tend to be frequent in hadith — but with significant outliers. Some roots are far more prominent in hadith than their Quranic frequency would predict (practical, legal roots), while others are Quran-heavy but rare in hadith (cosmological, poetic roots). These divergences reveal the different registers of revelation vs. prophetic teaching.

Built On

Itqan builds on and extends three open-source projects. Full technical details in the GitHub README.

KASHAF

Isnad visualization concept and Sankey data model. Itqan extends it from Bukhari-only to 11 books with D3, narrator grading, and interactive controls.

BasilSuhail

FAISS semantic search concept. Itqan upgrades from 15k hadiths to 112k, swaps the English-only model for multilingual-e5-small (Arabic-native), and adds root family tagging.

HadithRAG

RAG conversational Q&A with isnad-preserving retrieval. Itqan replaces GPT with open-source Qwen2.5, adds multi-turn, deduplication, and source grounding.

What’s Original in Itqan

The source projects provided concepts. Everything below was built from scratch and has no precedent in any open-source Islamic studies tool.

Quran–Hadith Root Bridge

1,590 shared Arabic roots connecting 6,236 ayahs to 112,000+ hadiths through 1,528,346 verified links. Click a root in the Quran, see every hadith across 18 books. No existing tool does this.

39 Thematic Families

Roots grouped by semantic field from classical lexicography (al-Raghib al-Isfahani). Mercy, justice, prayer, trade, eschatology — each family spans both Quran and Hadith.

Word-Level Morphology

33,758 Arabic words across 112k hadiths, each mapped to its root, Lane’s Lexicon definition, and grammatical form. Click any word in any hadith for instant analysis.

Largest Open-Source Rijal Database

115,735 narrator profiles parsed from 22 classical texts of hadith scholarship (Tahdhib al-Kamal, Mizan al-I’tidal, Al-Jarh wa al-Ta’dil, Al-Thiqat, and more). 217,762 name variants, 31,822 classical source cross-references. Multi-scholar comparison that previously required consulting several physical volumes — in one JSON file.

Concordance, Chords & Guide

A full Mu’jam al-Mufahris (1.15M word×hadith entries), three interactive chord diagrams with interpretive annotations, and a visual discovery guide — all new.
