If the retention (ḍabṭ) is light while the other attributes of ṣaḥīḥ remain present, it is al-ḥasan li-dhātihi (the fair in itself).
An accepted report safe from contradiction by another accepted report is al-muḥkam; if it is contradicted, it is mukhtalaf al-ḥadīth.
If the narrators of a ḥadīth agree in their wording of transmission, in any verbal feature, in an action, or in some shared quality, this is al-musalsal (literally, a chained or serial ḥadīth).
Khabar al-wāḥid is categorised, with respect to acceptance and rejection, into al-ṣaḥīḥ, al-ḥasan, and al-ḍaʿīf.
