===Levels of criticism===
#The least severe level for the criticism of a narrator is ''soft in hadith'' (''layyin al-ḥadīth'') and, according to al-'Iraqi, ''they have spoken about him'' (''takallamū fīhi''). This level would also be taken into consideration as a corroborating narrator, but at a level less than the lowest level of praise.
#Next is ''he is not strong'' (''laysa bi l-qawī''). The hadith of a narrator determined to be at this level would also be taken into consideration, as with the previous level, however, this narrator is weaker than one of the previous level.
#More severe than ''he is not strong'' is ''weak in hadith'' (''ḍaʻīf al-ḥadīth''), however, none of these first three categories are rejected outright.
#The fourth of the levels of severity of criticism includes terms such as: ''his hadith is rejected'' (''rudd al-ḥadīth'') and ''very weak'' (''ḍaʻīf jiddan'').
#The fifth includes terms such as: ''his hadith is abandoned'' (''matrūk al-ḥadīth'') and ''destroyed'' (''hālik'').
#From the most severe level of terms of criticism are: ''compulsive liar'' (''kadhdhāb''), ''he lies'' (''yakdhib'') and ''fabricator'' (''waḍḍāʻ'') among other terms.<ref name="Tadrib 1/573-80"/>
