Independent convergence with Sahih al-Bukhari
Our computational grading pipeline independently arrived at the same authenticity verdicts as classical scholars — without being trained on their conclusions.
Narrator reliability
12-Tier Grading System
Every narrator assessed across 12 tiers of scholarly reliability — from the most trustworthy to the fabricators.
Hadith authentication
Five Conditions of Authenticity
Every narration evaluated against the classical five conditions that scholars have applied for over a millennium.
- Chain continuity اتّصال السند
- Narrator uprightness عدالة الرواة
- Narrator precision ضبط الرواة
- Absence of anomaly عدم الشذوذ
- Absence of hidden defect عدم العلّة
Not everything is sahih. That's how you know it's real.
22% not graded — rather than force a classification, the corpus openly marks these narrations as ungraded. This reflects scholarly honesty: acknowledging the limits of current verification rather than overstating certainty.
How do I pray Tahajjud step by step?
وَمِنَ ٱلَّيْلِ فَٱسْجُدْ لَهُۥ وَسَبِّحْهُ لَيْلًا طَوِيلًا
Surah Al-Insan 76:26
Tahajjud is prayed after sleeping and waking during the last third of the night. The Prophet ﷺ would pray it in sets of two rak'ahs, then close with one witr. He was consistent in this practice throughout his life.
