Hadith

Major Sunni collections (AR + EN). Grades are study aids, not classical re-takhrīj. Bukhārī / Muslim = whole-book ṣaḥīḥ. Others use machine-extracted labels from matn wording (especially Tirmidhī formulas).

The four Sunan and Muwaṭṭaʾ carry per-report grades from published takhrīj works (Albānī, Arnaʾūṭ, Zubair Ali Zai et al., matched on the Arabic text); Musnad Aḥmad remains largely ungraded here. Grades summarize named scholars' judgments — consult the takhrīj literature for the reasoning.
