Al-ʿUṣūr al-Wusṭā 23 (2015): 141-142 Book Review Th i s i s e v i d e n t l y a n e d i t i o n o f Maḥjūbī’s doctoral dissertation from around 2003, under the direction of Muḥammad al-Ṣiqillī al-Ḥusaynī, presum- ably in Fez. It is a highly systematic survey of hadith terminology in Ibn Abī Ḥātim’s huge biographical dictionary, al-Jarḥ wa-al- taʿdīl. About half of his entries include an evaluation of the person’s hadith trans- mission, especially (in descending order of frequency) from his father, Abū Ḥātim (d. 277/890), Yaḥyā ibn Maʿīn (d. 233/848), Aḥmad ibn Ḥanbal (d. 241/855), and Abū Zurʿah al-Rāzī (d. 264/878). Maḥjūbī takes one term after another and gives first its dictionary (non-technical) definition, then its technical meaning, its appearance in prophetic hadith, if any, then the way it is used in al-Jarḥ wa-al-taʿdīl. This study will be useful principally as a reference, so that if one comes across an odd term, one can look it up to see how it used in al-Jarḥ wa-al-taʿdīl, e.g. malīʾ (new to me), meaning “trustworthy.” It seems to be accurate, at least as regards hadith terminology. Fairly often, Maḥjūbī goes beyond identifying usage in al-Jarḥ wa-al- taʿdīl, as when he interprets Yaḥyā ibn Maʿīn’s calling someone ṣuwayliḥ by means of quoting Ibn ʿĀdī, al-Dhahabī, and Ibn Ḥajar concerning the same man (134-5). The dubious underlying assumption is evidently that characterizations of men are effectively observations of fact, so that Ibn ʿĀdī and the rest must have meant exactly the same thing as Yaḥyā ibn Maʿīn. Occasionally, however, Maḥjūbī does recognize change over time; for example, the concentration of ninth-century critics on isnād comparison to define who was thiqah (“trustworthy”) where critics of the High Middle Ages such as Ibn al-Ṣalāḥ stressed personal characteristics such as probity and precision (81). He is not so good at terminology outside the field of hadith; for example, when he quotes Ibn Ḥibbān as saying that someone was a mujtahid as if it were relevant to his reliability as a traditionist (129), whereas this quotation must mean rather that he ʿAbd al-Raḥmān Maḥjūbī, Al-Muṣṭalaḥ al-ḥadīthī min khilāl Kitāb al-Jarḥ wa-al-taʿdīl li-Ibn Abī Ḥātim al-Rāzī (240-327 H) [Ḥadīth terms by way of Kitāb al-Jarḥ wa-al-taʿdīl by Ibn Abī Ḥātim al-Rāzī].

Another example: he defines the abdāl as ʿthe virtuous, trustworthy ones given to renunciation and worship’ (156) without reference to the theory of substitution (that each one can be said to have taken the place of another, deceased intercessor), association with Syria, and so on. I also missed a few terms, outstandingly laysa bi-dhāk. In all, then, this is a workmanlike s t u d y , s o m e w h a t u n i m a g i n a t i v e b u t useful, still, for understanding particular expressions of early hadith criticism.
