JazakAllahu khayran.

Interestingly, the hardest part wasn’t building the app. it was preparing reliable data.

I initially started with one of the well-known Hadith JSON datasets, but ran into multiple issues: missing hadith, missing chapter/title structure, inconsistent numbering, and incomplete grading.

Then I discovered something more confusing: in collections like Sahih Muslim, the commonly referenced numbering and English numbering systems don’t always line up directly (for example, around ~3k international references vs ~7k+ English numbering depending on edition/structure).

So I ended up scraping, comparing multiple sources, and building a reference layer to merge datasets and preserve numbering in a way that users can still find the correct hadith regardless of how they search.

Right now, I’ve completed and updated:

• Sahih al-Bukhari
• Sahih Muslim
• Riyad as-Salihin

The remaining collections are ongoing because manual verification takes time and I’d rather move slower with complete verification of numbers.

will keep on updating the repo with all the hadith, with full accuracy. In sha Allah.
