Tabayyun means seeking clarity before you speak or act.

In Surah Al-Hujurat, believers are told to verify news before acting on it. Tabayyun applies that discipline to software: retrieve from a known corpus, show the sources, and withhold what cannot be confirmed.

Standard answers are drawn from 115,805 indexed sources — the full Qur'an (6,236 verses), six major hadith collections, and multiple classical tafsir works. We do not invent a tafsir-passage total. Hadith trust is not flattened: Bukhari and Muslim are treated as canonical ṣaḥīḥ collections; the four Sunan often carry mixed grades, which are shown when the record has them.

We do not claim infallibility. We claim that the process is inspectable: fail-closed citation checks, grading left intact where the record has it, and Scholar Mode labeled when it goes outside the verified library.

Tabayyun is being built as a source-grounded workspace where users can ask questions, inspect sources, conduct research, and build khutbahs.
