Silsilat al-Ahadith as-Sahihah

سلسلة الأحاديث الصحيحة

A modern hadith authentication project by the 20th century's foremost hadith verifier. Al-Albani collected and authenticated hadith from across classical sources, providing detailed analysis of each chain of narration. The series, along with its companion Silsilat ad-Da'ifah (weak narrations), represents the most extensive modern effort to grade hadith outside the classical canon.
