Abstract

The type of ‘Al-isnād al-āli’ (higher chain of authority) which has great importance for the science of ḥadīths that constitutes the second best source of the Islam, expresses the value in terms of its proximity to the period of the Prophet Muhammad (peace be upon him). If ḥadīth has ‘al-isnād al-āli’ in the works of the scholars provides us with assurance on the intend of the ḥadīth. For this reason, the values of the works of those authors who have constructed their works with al-isnād al-āli undoubted in the science of ḥadīth. However the work of Abu al-Jahm al-Bāhilī’s (d. 228/842) named al-Juz‘ had that kind of ḥadīth, it has not appreciated by scholars, he could not get enough attention in his period and after it. His work contains famous scholar al-Layth Ibn Sa‘d’s (d. 175/791) narrative who claimed by ḥadīth scholars that his students neglected and omitted his ḥadīths and knowledge. Al-Layth Ibn Sa‘d was known doing transmission by written copies. The similarity of al-Layth Ibn Sa‘d narrations in al-Juz‘ with al-Layth narrations, which are also found in other sources, strengthens the claims of the existence of a narrative process based on the written texts in the early periods. In this study, these transfers of Abu al-Jahm reflected on other works will be examined and tried to build narrations of his teacher al-Layth Ibn Sa‘d. country, we can say that the article will contribute to the studies of the history of religions.Summary: Ḥadīth works written in the third century of hijri are the most distinguished sources. The most fundamental works in the science of ḥadīth were written in this time. In the following period, numerous studies have been committed to paper on them. One of the eminent works is the named al-Juz’, which belongs to Abu al-Jahm al-Bāhilī (d. 228/842). The author was not a person that was taken into consideration much during his time. It is possible to that he has been criticized about his scientific proficiency (al-Jarh). Nevertheless, al-Juz’ attracts attention due to the fact that it contains the type of ‘al-Isnād al-āli’ (higher chain of authority). Al-Isnād al-āli, which means access with the least number of narration from the author to the Prophet has very major role to determining of being dependable and certainty of the ḥadīths. The work of Abu al-Jahm which contains the ‘al-Isnād al-āli’ did not attract enough attention. However, another value of the al-Juz‘ is that its been included the narration of famous muhaddith Al-Layth Ibn Sa'd (d. 175/791). He is one of the valued mujtahid imams who have played an active and important role in second century of hijri. Al-Layth's narrations have been available insufficient amount present day. At this point the al-Juz‘ of Abu al-Jahm has great important because it contains many narrations of his shaykh Al-Layth Ibn Sa'd.The Juz‘ seems to has attracted the attention of the ḥadīths scholars in the following period. Indeed, various authors had the get authorization to narrate al-Juz‘. Furthermore, it is also known that some scholar in his period utilized his narration in their own study. For in¬stance, it was declared by Ibn Ḥajar (d. 852/1449) that al-Bukhārī (d. 256/870) had a narra¬tion belonging to Abu al-Jahm in his work ‘al-Ṣaḥīḥ al-Bukhārī’ with a muʻallaq chain (Omit¬ting his name). In the following periods, we come across famous muhaddith such as Aḥmad b. Ḥanbal (d. 241/855), al-Ṭabaranī (d. 360/971), Abū Bakr al-Marwazī (d. 292/905), al-Dāraquṭnī (d.385/995) and al-Bayhaqī (d. 458/1066) who received qualify of Juz's narra¬tion. Although the narrations of Abu al-Jahm are included in the prominent works of schol¬ars, it is clearly seems that the Juz‘ had not enough value except being procure as a written text. As far as we determined there are eleven narration of Abu al-Jahm in the main ḥadīth sources. In addition, we detected that some studies which contain some ḥadīth of al-Juz’ are list them in the same layout and order. This situation indicates that al-Juz’ is owned by these people as a duplicated edition and they narrated by not only orally transmitted but also spread by writing copy. This inference strengthens the theory which conceived by Modern researcher Fuad Sezgin (1924-2018) that ḥadīth transmission had conducted not only through oral transfer but also through written copies.Even though he lived in a very active time of oral transmission of ḥadīth and the time of specific journey for learning and pursuing ḥadīth, it is seen that Abu al-Jahm formed his Juz‘ from the ḥadīths that he procured only from his six shaykhs. That was quite less amount in that period. Juz‘, has an ʿAlāʾ al-Rijāl classification (ranked according to narrators) as ex¬pected in his period method. Abu al-Jahm began his study with his shaykh Al-Layth Ibn Sa'd’s narration, then completed with Sufyān ibn ʿUyayna’s. Juz‘ includes 112 ḥadīths. Ex¬cept two muʻallaq isnāds (omitting one or more narrators), all of ḥadīth has muttaṣil isnāds (narrators in the chain connected each other without omitting). Al-Juz‘ available nowadays in a published form. It seems that some of ḥadīth datas included in the Juz‘ have content against Islamic juris-prudential judgements. For example, the Prophet’s sayings ‘One or two swallow of breast milk does not make haram’ and ‘Nobody can fast or pilgrimage for the benefit of someone else’; allowing to Subay‘a al-Aslamī to marry without waiting her ‘iddah (waiting period of a woman after the death of her husband or divorce); when she gave birth, ʿUthmān b. ʿAffān’s permission to al-Rubay‘a bint Mu‘avvidh not to wait her ‘iddah; when ʿAbd Allāh b. ʿUmar has nasal bleeding he leaves the prayer, goes to wash, then back and continue where he leave off, without taking ablution; and describing marriage with polytheist women as for¬bidden (ḥarām). Of course, all this information must be examined within the framework of Islamic jurisprudence. However, Abu al-Jahm stands alone (tafarrūd) in such issues, it can be seen as the reasons to be recognized as a censured person (majrūḥ).Al-Juz‘ included 66 isnāds of Al-Layth Ibn Sa'd’s narration. Therefore it leaves behind all the works that compile the narration of Ibn Sa'd. That is why, we hypothesize that Juz‘ is a form of Al-Layth’s study that has survived to the present days. As a matter of fact, the muhaddiths who included the narrations of Al-Layth in their works, especially Ibn ḳuṭlūbughā could not ignore the Juz‘ of Abu al-Jahm; on the contrary, they took it as reference. In this case, it should be said that Abu al-Jahm al-Bāhilī is a loyal follower of Al-Layth and the word at¬tributed to Imām Shāfi‘ī and characterizing Al-Layth’s followers with disloyalty is invalid.
