Concept:Hasan is a technical term used by Hadith scholars to grade how reliable a narration is.
Explanation:Hadith scholars classify narrations according to the strength of their chains of transmission.
The highest grade is
Sahih, meaning authentic.
The next grade is
Hasan, which literally means good or fair.
A Hasan Hadith has an unbroken chain of narrators.
Its narrators are trustworthy and known for accuracy, though slightly less precise than those of a Sahih Hadith.
It is free from hidden defects and unusual contradictions.
Because of this, scholars accept a Hasan Hadith as a valid proof in Islamic rulings.
It stands in contrast to
Da′if (weak) and
Mawdu′ (fabricated) Hadith.
In simple terms, Hasan describes a Hadith that is sound and reliable for practice.
