Daʻīf

Ḍaʻīf (ضَعِيْف) is the categorization of a hadith as "weak". Ibn Hajar described the cause of a hadith being classified as weak as "either due to discontinuity in the chain of narrators or due to some criticism of a narrator."[10] This discontinuity refers to the omission of a narrator occurring at different positions within the isnād and is referred to using specific terminology accordingly as discussed below.
