Al-Bulqini commented that"the terminology of the hadith specialists is more than this, while,
at the same time, is only Ṣaḥīḥ and its opposite.
He then defines a hadith that is Ṣaḥīḥ lighairihi-"Ṣaḥīḥ due to external factors"-
as a hadith"with something, such as numerous chains of narration, strengthening it.
While the individual terms of hadith terminology are many, many more than these three terms, the final outcome is
essentially determining whether a particular hadith is Ṣaḥīḥ and, therefore, actionable, or ḍaʻīf and not actionable.
Ibn Hajar defines a hadith that is ḥasan lithatihi-"ḥasan in and of itself"-
with the same definition a Ṣaḥīḥ hadith except that the competence of one of its narrators is less than complete;
while a hadith that is ḥasan ligharihi("ḥasan due to external factors") is determined to be ḥasan due to corroborating factors such as numerous chains of narration.
