About IsItSahih
An educational Islamic claims verification tool. Not a fatwa service.
What We Do
IsItSahih helps you verify whether an Islamic claim, statement, or practice is supported by
the Quran or authentic Hadith. You enter a claim — for example, "Is it permissible to pray
with shoes on?" — and the tool searches primary Islamic sources and returns a verdict
(True, False, or Uncertain) with the actual Arabic text and English translation of each
supporting reference.
Every result is stored permanently at a unique URL (/share/{id}), so you can
share exact verified findings without re-running the check.
Our Methodology
1
Semantic Search
Your claim is sent to Kalimat.dev, a semantic vector search engine trained on Islamic
scripture. It searches both the Quran and six Hadith collections
(Sahih al-Bukhari, Sahih Muslim, Sunan Abu Dawood, Sunan an-Nasa'i, Sunan at-Tirmidhi,
Sunan Ibn Majah) and retrieves the most semantically relevant passages. Only Hadith
graded Sahih (authentic) or Hasan (good) are included — weak or
fabricated narrations are excluded by default.
2
AI Verdict — Constrained to Retrieved Sources Only
The retrieved passages are passed to Gemini AI with a strict prompt: the AI may only
render a verdict based on what the search returned. It cannot invent citations, paraphrase
scripture, or draw on general training knowledge about Islam. If the retrieved sources
do not clearly support a True or False verdict, the system defaults to Uncertain.
3
Integrity Guard
A final check removes any reference that the AI did not explicitly mark as relevant.
If a True or False verdict is returned with zero supporting references after this
filtering step, it is automatically downgraded to Uncertain. This prevents
confident-sounding verdicts without evidential basis.
Sources
- The Holy Quran
- Sahih al-Bukhari (compiled by Imam Muhammad al-Bukhari, d. 870 CE)
- Sahih Muslim (compiled by Imam Muslim ibn al-Hajjaj, d. 875 CE)
- Sunan Abu Dawood (compiled by Imam Abu Dawood al-Sijistani, d. 889 CE)
- Sunan an-Nasa'i (compiled by Imam Ahmad an-Nasa'i, d. 915 CE)

- Sunan Ibn Majah (compiled by Imam Ibn Majah, d. 887 CE)
These six collections, collectively known as the Kutub al-Sittah, are the most
widely accepted Hadith compilations in Sunni Islam and form the scholarly standard for
Hadith authentication.
Important Limitations
Not a Fatwa
IsItSahih is an educational reference tool. Verdicts are based on AI analysis of
retrieved primary sources. They do not constitute religious legal rulings (fatwas) and
may not reflect the consensus of Islamic scholars or the positions of particular schools
of jurisprudence (madhabs).
For personal religious decisions, please consult a qualified Islamic scholar.
Results reflect what is found in the above collections and may differ from rulings
based on weak Hadith, regional scholarly tradition, or later jurisprudential consensus.
Languages
IsItSahih supports verification in English and Bangla (Bengali). Arabic text is always
displayed verbatim — we do not translate or paraphrase scripture.
