Hadith report, the scale of the report's transmission, the routes through which the report was transmitted, and the individual narrators involved in its transmission. On the basis of these criteria, various classifications were devised for hadith. The earliest comprehensive work in hadith studies was Abu Muhammad al-Ramahurmuzi's "al-Muhaddith al-Fasil", while another significant work was al-Hakim al-Naysaburi's "Ma‘rifat ‘ulum al-hadith". Ibn al-Salah's "ʻUlum al-hadith" is considered the standard classical reference on hadith studies. By means of hadith terminology, hadith are categorized as "ṣaḥīḥ" (sound, authentic), "ḍaʿīf" (weak), or "mawḍūʿ" (fabricated). Other classifications used also include: "ḥasan" (good), which refers to an otherwise
Criticism of Hadith to be obsessed with isr’iliyyat, i.e. tales from Jewish lore about earlier prophets. According to author Israr Ahmed Khan, traditional methods used to establish authenticity of hadith rely almost entirely on the personal characters of the reported narrators, and fail to pay enough attention to the actual content of the hadith being evaluated. Among the problems he sees in the traditional hadith analysis are: the inability of some narrators to maintain preciseness of the report, textual conflicts among reports, ignoring textual analysis when the hadith was reported by a narrator of good character, and probability of fabrication of hadith.
