Hadith

Oral traditions and early sectarianism

Though the authenticity of any of the Hadith has come under increasing scrutiny in modern times (in light of scholarship on the reliability of oral traditions, virtually unending political conflicts after Muhammad's death, frequent internal contradiction, and, often, clear cases of fabrication), the early scholars of Islam responsible for the transcription of the hadith did themselves employ a seemingly sophisticated method of verification that relied on the plausibility of: the "chains" of transmission (or asaneed; sing. isnad) allegedly connecting the hadith back to the prophet, the reliability of the narrators' morals and memory, and, indeed, the matn, or text, of the hadith itself (that is, the plausibility of the prophet actually having said/done what the report attests to).

Despite this apparent rigor, the hadith would ultimately be compiled along sectarian, political, and polemical lines, generally with narrations supporting the compiling group's point of view (matn-based analysis playing no small part in this outcome). Today, Sunnis and Shi'ites have separate collections of hadiths. That the meaning of "hadith" extended to include the sayings and doings of Muhammad's companions, many of whom would be deeply embroiled in the political turmoil that would follow Muhammad's death (prominently, Ali and Aisha), only facilitated the splitting of the tradition.

Degrees of authenticity

While circumstances surrounding and preceding the compilation of the hadith cast the entire corpus in a dubious light, the hadith cannot be viewed as entirely reliable or unreliable, as even hadith scholars themselves differentiate(d) between what they grade(d) as:

Sahih (authentic),

Hasan (good),

Da'if (weak),

Mawdu' (fabricated hadith),

and Munkar (rejected; referring usually to less reliable hadith that contradict more reliable hadith).

Consequently, even from an Islamic standpoint, the vast, vast, majority of hadith floating around prior to the compilation of the hadith are considered unreliable. Most famously, the Sunni scholars Imam Bukhari (d. 870) and Imam Muslim (d. 875) are said to have sifted through hundreds of thousands of narrations to ultimately decide only a few thousand were truly reliable. Slightly earlier collections of hadith do exist, famously the collections of Imam Malik (d. 795) and Imam Ibn Hanbal (d. 855), but these are not considered as altogether reliable (even if individual traditions within these works are reliable) as the collections of Bukhari and Muslim.

Collections of hadith, unlike the Qur'an, are generally grouped topically, chronologically, or by the companion who is alleged to have narrated them (this last type of organization within a collection of hadith renders the work a musnad, such as the Musnad of Imam Ahmad).^[1]

The word 'Sunni' comes from the word 'Sunnah', and most of the world's Muslims (as many as 80-90%)^{[2][3][4][5][6]} follow this Sunni form of Islam. There are certain Hadith collections considered by most Sunnis to be trustworthy and these are commonly known as the Authentic Six. Only two of them, however, are considered entirely authentic (sahih), and these are Bukhari and Muslim. These collections are second only to the Qur'an in authority. The others are from Abu Dawud, Tirmidhi, Nasa'i, and Ibn Majah. In strength, Malik's Muwatta' is placed just below the two Sahihs, but is not generally included among the authentic six.^[7]

Online hadith collections in English

• Sahih Bukhari
• Sahih Muslim
• Sunan Abu Dawud (partial)
• Malik's Muwatta
• Jami al-Tirmidhi
• Hadith Qudsi (hadith which contain non-Qur'anic words from Allah, repeated by Muhammad)

In Shi'ite Islam (approx 10-20% of the world's Muslim population)^[2][8][5][6] they have their own collections and are more particular in regards to the Hadith narrations they will accept. If a narrator was not a member of the Ahl al-Bayt (Muhammad's household) or one of their supporters, then the narration is typically rejected. For example, they reject narrations from Abu Huraira. Al-Kafi is considered the most reliable collection of Shi'ite hadith.^[9]

This minority group rejects the Hadith altogether and are classed as heretics by mainstream Islam. This "Qur'an-only" approach to the Islamic faith is not without its criticisms, as in the absence of hadith, much of Islamic ritual and religious history lacks basis.
