Criteria for Authenticating Hadith

Hadith scholars developed a rigorous methodology for evaluating the authenticity of prophetic traditions. This science, known as Mustalah al-Hadith, examines both the chain of narration (isnad) and the text (matn).

Conditions for a Sahih (Authentic) Hadith

1. Continuous chain of narration (ittisal al-sanad)
2. Integrity of narrators (adalah)
3. Precision of narrators (dabt)
4. Freedom from irregularity (adam al-shudhudh)
5. Freedom from hidden defects (adam al-illah)

If a hadith meets all five conditions, it is classified as sahih (authentic). Missing one or more conditions results in different classifications such as hasan (good) or da'if (weak).
