The Difference between Ḥadīth and Sunnah

 

1.       A Ḥadīth is established through the authenticity of its chain of transmission (sanad), yet it is not classified as Sunnah unless it is consistently practiced and the Companion who narrated it adopted it into his own practice. Rasūlullāh ṣallallāhu ‘alayhi wa sallam designated Sunnah—not Ḥadīth—as the second source of knowledge. Furthermore, in the early centuries, those who stood against the Mu'tazila, Rawāfiḍ, and Khawarij became known as Ahl al-Sunnah, not Ahl al-Ḥadīth.

2.       In classical terminology, Ahl al-Ḥadīth referred to a scholarly rank rather than a specific school of thought, much like the terms Ahl al-Tafsīr (scholars of exegesis) or Ahl al-‘Arabiyyah (scholars of Arabic language).

3.       A narration does not become a binding authority (ḥujjah) merely based on the authenticity of its chain of transmission; the ruling contained within it might have been abrogated. However, for the Ahl al-Ḥadīth (in the modern sense of the term), such a narration remains actionable, and the fact that it has been abrogated does not prevent it from serving as an authority. Their prominent scholar, Maulana Nazir Hussain Dehlvi, writes: "If a knowledgeable person, to the best of their ability, researches a Ḥadīth and acts upon it—and the ultimate outcome turns out to be that the Hadith was actually abrogated—then we maintain that the person would not be considered sinful for acting upon it, nor would their action be deemed invalid or requiring repetition." [Mi'yār-ul-Ḥaq, p. 41]

4.       This clarifies that the Ahl al-Ḥadīth (in the modern sense) regard Ḥadīth itself as a binding religious authority (ḥujjah). In contrast, Ahl al-Sunnah maintain that Rasūlullāh ṣallallāhu ‘alayhi wa sallam identified Sunnah—not Ḥadīth—as the second source of knowledge.

5.       A Ḥadīth can be weak (ḍa'īf), whereas Sunnah is never weak. An action that occurred only sporadically—such as urinating while standing—may constitute a Hadith, but it cannot be termed Sunnah.

6.       In terms of practice, the principle of "Mā ana 'alaihi wa Aṣḥābī" (that upon which I and my Companions stand) is regarded as the criterion of truth—a standard established by Ḥadīth itself. Thus, Ḥadīth serves as a source of knowledge; in the early era, those possessing knowledge of Ḥadīth were designated as Ahl-e-Ḥadīth (People of Ḥadīth), just as Ahl-e-Tafsīr (People of Exegesis) and Ahl-e-Adab (People of Literature) were recognized as adherents of their respective disciplines.
