The Science of Jarh and Ta’dil
In linguistic terms, “jarh” refers to the act of causing an injury to something, typically with a weapon, leading to a cut or a tear. In the context of hadith scholars, however, it pertains to a characteristic of narrators that can undermine their integrity—specifically, their reliability and ethical conduct, as well as their ability to accurately transmit hadiths. This results in the rejection or weakening of their narrations. Conversely, “ta’dil” denotes the process of evaluating and affirming something. In hadith terminology, it represents a characteristic of narrators that entails a judgement of their integrity and ability to retain hadith accurately, validating their narrations. Thus, jarh and ta’dil constitute a field of study wherein expert hadith scholars thoroughly investigate the conditions of narrators, determining their credibility or otherwise, with the ultimate aim of preserving the integrity of the prophetic tradition and safeguarding Islamic law from disreputable claims or misrepresentation.
Origins of the Science of Jarh and Ta’dil
The Companions of the Prophet Muhammad (peace be upon him) stressed the importance of caution when accepting hadiths from their narrators, advocating for the selection of trustworthy individuals known for their piety and memory. A trustworthy narrator is one who embodies justice, while a reliable memorizer is one who is adept and precise in recalling hadith. However, the emergence of various sects and proponents of heretical innovations following the era of the Companions and their successors led to the deliberate distortion and fabrication of hadiths to support sectarian views and innovations. Consequently, these heretics would invent false narrations to legitimize their positions. Prior to these disturbances, hadith scholars did not scrutinize the chains of narration (isnad)—the series of narrators leading back to the Prophet Muhammad. With the rise of these challenges, scholars began to assess the backgrounds of hadith narrators: accepting narrations from those of religious adherence and strong retention, while dismissing those from heretics and innovators. As noted by Ibn Sirin, the practice evolved: “Initially, we did not inquire about the isnad. However, when discord emerged, we advised them to name their narrators; we accepted the hadith of those from the Sunnah and rejected that of those from sects.” Accordingly, a common principle emerged among the general populace: the narrations of the Prophet (peace be upon him) are religious doctrines, hence, they should ascertain the sources of their faith.
Criteria for Jarh and Ta’dil
Scholarly consensus has established several criteria that must be met by those who engage in jarh and ta’dil to ensure their assessments of hadith narrators are sound, precise, and just. These criteria include:
- The individual must be knowledgeable, just, and characterized by piety and truthfulness. Imam Al-Dhahabi remarked in his work, “Mizan Al-I’tidal”: “Assessing narrators requires complete piety, freedom from bias, and thorough expertise regarding hadith and its nuances.”
- The individual must possess an understanding of the reasons behind jarh and ta’dil, ensuring fairness when judging narrators. Badr Al-Din Ibn Jama’ah stated, “If a person is not knowledgeable about the reasons behind these assessments, their jarh and ta’dil will not be accepted, whether general or specific.”
- They must be detached from worldly desires and free from sectarian bias.
- The individual should be proficient in understanding the Arabic language, ensuring that each term is used appropriately; thus, a narrator cannot be unjustly criticized based on a term that lacks relevance in juristic evaluation.
Classifications of Jarh and Ta’dil Literature
The literature on hadith scholars is essential for understanding the status of narrators concerning their credibility. This body of work can be categorized into four main types:
- The first category consists of works dedicated to trustworthy narrators. An example is “Kitab Al-Thiqat” by Ibn Hibban.
- The second category pertains to works concerning weak narrators, such as Al-Bukhari’s “Al-Du’afa Al-Saghir” and Ibn Hajar’s “Lisan Al-Mizan.”
- The third category encompasses works that include both trustworthy and weak narrators, exemplified by Al-Bukhari’s “Al-Tarikh Al-Kabir” and Ibn Sa’d’s “Kitab Al-Tabaqat Al-Kubra.”
- The fourth category is dedicated to the narrators of the six well-known collections of hadith related to the Prophet Muhammad (peace be upon him), with “Tahdhib Al-Kamal fi Asma Al-Rijal” by Al-Mizzi as a noteworthy example.
