Historically, some sects of the
Kharijites rejected the Hadith. There were some who opposed even the writing down of the Hadith itself for fear that it would compete, or even replace the
Qur'an.
Mu'tazilites also rejected the hadiths as the basis for Islamic law, while at the same time accepting the Sunnah and
ijma. Similarly, critics of collection and/or use of hadith in Islam can be found in the early era when the classical consensus of
al-Shafiʿi was being developed and established (particularly by the
ahl-i-kalam and Muʿtazilites) and many centuries later in the modern era when Islamic reformists (such as the
ahl-i-Quran and thinkers such as
Syed Ahmed Khan,
Muhammad Iqbal) sought to revitalize Islam. Although scholars and critics of the Hadith such as
Aslam Jairajpuri and
Ghulam Ahmed Perwez) have "never attracted a large following", they and others who propose limitations on usage of
ḥadīth literature outside of the mainstream include both early Muslims (
Al-Nawawi,
Wāṣil b. ʿAṭāʾ,
Ibrahim an-Nazzam) and later reformers (Syed Ahmed Khan, Muhammad Iqbal). Both
modernist Muslims and Quranists believe that the problems in the
Islamic world come partly from the traditional elements of the hadith and seek to reject those teachings.
Medieval criticism Sunnis Whether al-Bukhari and other traditional hadith scholars were successful in narrowing down hadith to its authentic "core" is disputed among Sunni Muslim scholars, especially prior to the early modern era.
Al-Nawawi wrote that "a number of scholars discovered many hadiths" in the two most authentic hadith collections known as the
Sahihayn—
Sahih al-Bukhari and
Sahih Muslim—"which do not fulfill the conditions of verification assumed" by the collectors of those works. Al-Ghazali addresses questions from an unnamed "questioner" about a number of problems the questioner sees in several hadith, such as "Satan runs in the blood vessels of one of you"; "satans nourish themselves from manure and bones"; and "Paradise is as wide as heaven and earth", yet it must be "contained somewhere within the bounds of those two?" In the fifteenth century, when
Ibn Hajar al-Asqalani encountered the hadith • When `God created Adam, and he was sixty arms tall,' and that, after Adam fell, 'mankind has continued to shrink since that time.' he noted that the ancient inhabitants of houses carved out of cliffs he had seen must have been about the same size humans of his day, simply "admitted frankly that 'to this day, I have not found how to resolve this problem, without doubting the hadith's authenticity. However, with the rise of natural sciences and technology of the West, some Muslims came to a different conclusion. Critics also complained of hadith that sound less like what a prophet would say than someone in the post-Shafiʿi era justifying fabricating hadith. Such as • '[Sayings attributed to me] which agree with the Koran, go back to me, whether I actually said them or not', and • 'Whatever good sayings there are, I said them.' Joseph Schacht argues that the very large number of contradictory hadith are very likely the result of hadith fabricated "polemically with a view to rebutting a contrary doctrine or practice" supported by another hadith. While criticism of the authenticity of any hadith in the Sahihayn ceased during the early modern era, it has been revived again by the
Salafi movement, a prominent example of this being
Al-Albani.
Kalam theologians According to scholar
Daniel W. Brown, the questioning of the authenticity, scholarship and importance of Hadith goes back to the second century of Islam when al-Shafiʿi was establishing the final authority of a hadith of Muhammad in Islamic law. An opposing group, known as
Ahl al-Kalam (or the
Kalam theologians), were "highly critical of both the traditionists' method and the results of their work", doubting "the reliability of the transmission" of the hadith, including the traditionists' evaluation of the "qualities of the transmitters" of hadith they considered "purely arbitrary", and thought the collections of hadiths to be "filled with contradictory, blasphemous, and absurd traditions." They did not doubt that Muslims ought to follow the example of the prophet, but maintained his "true legacy" was found "first and foremost in following the Quran"—an "explanation of all things" ()—which hadith "should never be allowed to rule on". If a question was "not referred to in the Qur'an",
Ahl al-Kalam "tended" to regard it as "having been left deliberately unregulated by God." They contended that obedience to the Prophet was contained in obeying only the Qur'an that God has sent down to him, and that when the Qur'an mentioned "the Book" together with "Wisdom" (, , ), "Wisdom" was not another word for hadith, but for "the specific rulings of the Book".
Mutazilites Later, a similar group, the
Mu'tazilites (which flourished in Basra and Baghdad in the 8th–10th centuries CE), also viewed the transmission of the Prophetic sunnah as not sufficiently reliable. The Hadith, according to them, was mere guesswork and conjecture, while the Quran was complete and perfect, and did not require the Hadith or any other book to supplement or complement it." Mutazilites believed that hadith were susceptible to ideological manipulation, that scrutiny of authenticity should be extended to the
matn (content) of the hadith and not just the
isnad, and that only
mutawatir hadith should be accepted (i.e. hadith so widely transmitted that it was thought they could not be invented). In later periods, it was still accepted (such as with
Al-Nawawi in the thirteenth century CE) that
ahad hadith (those with a single chain of transmitters) only yield theoretical probability of historicity and not certainty. However scholars like
Ibn al-Salah (d. 1245 CE), al-Ansari (d. 1707 CE), and Ibn ‘Abd al-Shakur (d. 1810 CE) found "no more than eight or nine" hadiths that fell into the
mutawatir category.
Wāṣil b. ʿAṭāʾ (700–748 CE) defined a
mutawatir hadith as one passed on by four independent transmitters, inspired by the juridical notion of the necessary number of witnesses needed as proof that an event took place (and to the exclusion that they all collaborated on a lie). Abū l-Hudhayl al-ʿAllāf (d. 227/841) suggested that twenty transmitters were needed with at least one being a believer.
Modern criticism Since the 19th century Islamic scholar
Syed Ahmed Khan, three important subjects concerning Islamic discourse on hadith included the character and competence of the
Companions of the Prophet, scrutiny over the means of the preservation and transmission of hadith, and discourse on how efficacious sinad criticism itself was in parsing between genuine and unreliable traditions. Many conservative revivalists and liberal modernists of 20th century believed that a recourse to the Quran should be made in evaluating the Sunnah, contrary to
Al-Shafiʽi and classical hadith criticism.
Revivalists Revivalists (like
Shah Waliullah Dehlawi,
Shibli Nomani,
Rashid Rida, Salafi Jamal al-Din al-Qasimi,
Abul A'la Maududi, and
Mohammed al-Ghazali), however, believed in the classical principles of hadith and Shariah law and held highly negative views about those who express skepticism towards classical hadith collections. Nevertheless, some also believed in the re-examination of those classical collections and enhancing emphasis on the content (matn) of hadith during evaluation. Later in the 20th century,
Salafist revivalists
Shibli Nomani,
Rashid Rida,
Abul A'la Maududi, and
Mohammed al-Ghazali also sought "to restore Islam to ascendency" (not just in India) and in particular to restore
Sharia to the law of the lands of Islam it had been before being replaced by "secular, Western inspired law codes" of colonialism and modernity. At the same time they agreed that restoring
relevant Sharia required "some reformulation" of the law, which would require a return to sources, which required agreement on how the sources were to be "interpreted and understand" and reassessment of hadith.
Shibli Nomani (1857–1914) argued that the traditional science of Hadith had errored by ignoring legal scholarship when its work "required the participation of legal scholars" (
fuqaha). Instead had been dominated by Hadith collectors (
muhaddith). Applying legal scholarship involved examining hadith content (
matn) for its spirit and relevance "within the context of the Sharia as a whole" according to the method of scholars of Islamic law (
fuqaha) and weeding out corrupted hadith inconsistent with "reason, with human nature, and with historical conditions". (Rather than hadith collectors being the scholars of hadith science, they more resembled "laborers" who provided the raw materials to the "engineers" of hadith—namely the scholars of Islamic law.)
Abul A'la Maududi (1903–1979), the leading South Asian revivalist of the 20th century, also argued
matn was neglected and resulting in Hadith collectors accepting "traditions that ring false" and rejecting "traditions that ring true". Maududi also raised the question of the reliability of companions of the prophet as transmitters of hadith, saying "even the noble companions were overcome by human weaknesses, one attacking another", and cited disputes among the companions: Ibn Umar called Abu Hurayra a liar; Aisha criticized Anas for transmitting traditions although he was only a child during the life of the Prophet, and Hasan b. Ali called both Ibn Umar and Ibn al-Zubayr liars. (Maududi's criticism clashed with the doctrine of classical hadith criticism that the collective moral character (
ʿadāla) of the first generation of Muslims was above reproach, and though Maududi strongly opposed modernists who thought hadith should be used sparingly or not at all in Islamic law, he nonetheless came under attack from traditional Islamic scholars (
ulama) for his views).
Quranism Another development was the view that the Quran (and sometimes mutawatir traditions) should be used to re-evaluate the Sunnah, as among
Mohammed al-Ghazali (1917–1996). While Shafīʿī and classical scholarship held that the "Sunnah rules on the Quran", al-Ghazali (and Shibli, Rashid Rida, Maududi) believed that the Quran must be "the supreme arbiter of the authenticity" of hadith. Rida "argued that all traditions at variance with the Quran should be discarded, irrespective of their chain of transmission". Examples of conflicts between the two sources were • whether consumption of beef was haram, (The Quran gave permission to eat it, but muhaddith
Muhammad Nasiruddin al-Albani declared it forbidden citing a hadith.) • Whether the murder of a non-Muslim should be punished just as the murder of a Muslim was—with
qiṣāṣ, or retribution. (When a non-Muslim engineer was attacked and killed in Saudi Arabia, a religious judge—
qadi—ruled that qiṣāṣ could not be applied to his murderer, citing a hadith stating
la yuqtalu muslimun fi kafirin. According to Muhammad al-Ghazali, this violated a Quranic principle of human dignity, though others do not find it in disagreement with the Quran.)
Modernists Later, in nineteenth century
British Raj, Islamic modernists like
Syed Ahmed Khan sought to deal with Western colonial influence and the decline of Muslim powers through greater understanding of science and application of reason. They often favored reinterpretation of some doctrines, including sharia law in favor of modern norms like equal rights, peaceful coexistence, and
freedom of thought. Ahmed Khan "questioned the historicity and authenticity of many, if not most, traditions, much as the noted scholars Ignaz Goldziher and Joseph Schacht would later do." He blamed corruption of hadith on transmission according to ''bi'l-ma'na
(sense of the story rather than verbatim) in particular, and "came to believe" only mutawatir hadith as "a reliable basis for belief independent of the Quran". Ahmed Khan was one of the pioneers of "the argument that the traditional hadith scientists (muḥaddithūn
) neglected criticism of the matn'' (hadith content)—emersed in the difficulties of "examining the trustworthiness" of the narrators of the hadith, "they never got around" to the task of examining the hadith content. One of the most influential modernist critiques comes from Mahmoud Abu Rayya, who argued that the basis of Islam rests on the Quran, reason, and mutawatir (as opposed to merely sahih) hadith. == Hadith limitations ==
