بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

Qur'an & Islamic study companion

رسوخRusukh

/ruˈsuːx/ — “firm rootedness”

The Qur'an companion that never invents sacred text.

Ask about the Qur'an and authentic hadith. Rusukh answers only by quoting verified sources, word for word — and when it can't cite one, it defers to a scholar. It never guesses.

Cite or defer — never generate.

Ask grounded

You How does the Qur'an open?

Established

Every chapter but one opens with the Basmala [1:1]:

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

“In the name of Allah, the Entirely Merciful, the Especially Merciful.”

source Qur'an Foundation ref 1:1 · Sahih Int'l checksum verified

The Rule — non-negotiable

Cite, or defer.
Never generate.

Every āyah, hadith and translation Rusukh shows is retrieved from a verified corpus, quoted verbatim, and validated against the database before it ever reaches your screen. Nothing sacred is ever spoken from a model's memory.

01 · INGESTION

Sourced & checksummed

No sacred text is hand-typed. Every row is pulled from an upstream authority and stamped with provenance and a sha256 checksum of the verified text.

02 · VALIDATION GATE

Re-checked before display

Every quote in an answer is verified against the corpus at request time — verse_exists(), hadith_grade() — or it is stripped. A grounded answer, or a defer.

03 · ACCURACY SUITE

Enforced in CI

A religious-accuracy test suite fails the build on any citation, hallucination, or grade breach. A breach of the Rule is a release blocker, not a warning.

// It is a study aid, not a mufti.

Four pillars

Study, grounded end to end.

Ask, Read and Hifz — one companion for questions, reading and memorization. Every pillar answers to the same Rule.

Q&A grounded in a verified corpus through hybrid vector + full-text retrieval. Every answer carries citation chips, a sources panel, and a scope banner — Established, Differs by school, or Consult a scholar.

An offline mushaf: Uthmani text with translation, per-verse recitation, and a surah index you can jump into by name or by reference like 2:255. Tap any verse to play, bookmark, or send it to Hifz.

حفظ

Memorization the way huffāẓ actually revise — Sabaq, Sabqi, and Manzil buckets layered over an SM-2 spaced-repetition engine. A daily queue, four-button self-grading, weak-spot logging, streaks, and a hands-free audio trainer.

What makes it trustworthy

Every quote carries its lineage.

Islamic scholarship authenticates knowledge by its chain of transmission. Rusukh does the same for every line it shows you.

Provenance on every row

Each displayed quote traces back to a verified upstream source. This is the record that travels with it:

Hadith grade is data, never decoration

Where a narration appears, its grade is shown verbatim from the stored value — and validated server-side before display.

Verbatim onlyQuotes are copied, not composed. The model may never author sacred text.

Row-level securityPostgres RLS guards every user and tenant table on the backend.

Server-side modelsThe app never calls a model directly — retrieval runs behind an edge function.

CI release-blockerAccuracy tests gate every release. A breach of the Rule stops the ship.

For masjids & networks

Your masjid's companion, in your masjid's colors.

Rusukh is built to be distributed through masjid and ICNA networks — and to compound with Deenify, the multi-tenant Masjid OS. Connect a community and the app becomes theirs.

One shared identity. Members sign in once across Rusukh and Deenify.
Tenant branding. A single seed color flows through the whole app.
The imam is the authority. The app supports that relationship — it never replaces it.

firm rootedness

Rooted in what's verified. Honest about what isn't.

“I could not find an adequate, verified source for this question in the available corpus. Rather than guess, I would encourage you to consult a knowledgeable scholar or your local imam.”
