应当熟悉圣训学者（muhaddithin）经常使用的术语的含义。它们是：hadīth（圣训）、khabar（传闻）、athar（圣迹）和Sunnah（逊奈）；从圣训及其传述的角度来看：matn（正文）、sanad（传述系统）、isnād（传述链）、musnad（有传述链的圣训集）和musnid（编纂有传述链圣训的学者）；从传述者的角度来看：muhaddith（圣训学家）、hāfidh（熟背圣训者）、hujjah（圣训权威）和hākim（圣训鉴定权威）。至于这些词在圣训术语中的含义阐释，内容如下：

One should be familiar with the meanings of terms that are frequently used by the muhaddithin. They are: hadīth, khabar, athar and Sunnah; from the perspective of the terms of hadīth and its transmission: matn, sanad, isnād, musnad and musnid; from the perspective of the transmitters: muhaddith, hāfidh, hujjah and hākim. As for the exposition of the meanings of these words in the terminology of hadīth, then it is as follows:

1. 圣训（Hadīth）：凡归于先知的言论、行为、默许或体貌特征的内容，即与其被造之形相关的内容，例如他既不高也不矮，以及与其品性相关的内容，例如他从不以任何厌恶之事回应他人。Khabar（信息）与Sunnah（圣行）具有相同的含义，它们与hadīth一词同义。也就是说，hadīth、khabar与Sunnah三者含义相同。至于athar（圣伴之言），则是止于圣门弟子（Sahābah）的圣训（mawqūf）。

1. Hadīth: Whatever has been attributed to the Prophet  of his sayings, actions, consent or physical attributes i.e, relating to his creation such as his not being tall nor short, or his character, that is, relating to his character such as his [not countering anyone with anything makrūh]. Khabar and Sunnah have this same meaning. They are synonymous with the term hadīth. All of them, i.e, hadīth, khabar and Sunnah have the same meaning. As for athar it is the hadīth stopping [mawqūf] at the Sahābah .

2. matn（正文）：指圣训传述链（sanad）末端所指的那段话语本身。sanad是通向matn的传述路线，即引出该段话语的各位传述人。isnād（传述链）把圣训追溯到说出它的人。musnad（相连的）指其传述链从开头到结尾彼此相连、没有中断的圣训，即使它是mawqūf（止于门徒的）也是如此。musnad一词也用于指汇集门徒传述的圣训的书籍。至于musnid（传述者），则是指以其传述链来传述圣训的人。

2. Matn: The speech which comes at the end of the highest part of the sanad. The sanad is the path leading to the matn which is the men (transmitters) who lead to it. The isnād raises (links) the hadīth to the one who said it. Musnad is that (hadīth) whose chain connects its beginning to its end (without any breaks) even if it is mawqūf. The word musnad is also applied to a book in which transmissions of the Sahabah are collected. As for musnid it is the person who narrates the Hadith with its isnād.

3. 穆哈迪ษ（Muhaddith）：指传承圣训并专注于圣训的传述与含义的人。 哈菲兹（Hāfidh）：指能够背诵十万段圣训（包括matn正文与sanad传述系统，即使经由不同的传述途径）并明了其所需知识的人。 胡贾（Hujjah）：指精通三十万段圣训的人。 哈基姆（Hākim）：指全面精通整个逊奈（Sunnah）的人。

3. Muhaddith: someone who carries the hadīth and devotes his attention to it in terms of its transmission and meaning. The hāfidh: someone who has committed to memory a hundred thousand ahadīth with the matn and sanad even if through various lines of transmission and he is aware of what he requires. The hujjah: someone who is thoroughly acquainted with three hundred thousand ahadīth; and the hākim: someone who is thoroughly acquainted with the entirety of the Sunnah.
