Traditionalist theology is a movement of Islamic scholars who reject rationalistic Islamic theology (kalam) in favor of strict textualism in interpreting the Quran and sunnah. The name derives from "tradition" in its technical sense as translation of the Arabic word hadith. It is also sometimes referred to by several other names.
Adherents of traditionalist theology believe the zahir (literal, apparent) meaning of the Qur'an and the hadith are the sole authorities in matters of belief and law; and that the use of rational disputation is forbidden even verifying the truth. They engage in a literal reading of the Qur'an, as opposed to one engaged in ta'wil (metaphorical interpretation). They do not attempt to conceptualize the meanings of the Qur'an rationally, and believe that their realities should be consigned to God alone (tafwid). In essence, the text of the Qur'an and Hadith is accepted without asking "how" or "Bi-la kaifa".
Traditionalist theology emerged among hadith scholars who eventually coalesced into a movement called ahl al-hadith under the leadership of Ahmad ibn Hanbal. In matters of faith, they were pitted against Mu'tazilites and other theological currents, condemning many points of their doctrine as well as the rationalistic methods they used in defending them. In the tenth century al-Ash'ari and al-Maturidi found a middle ground between Mu'tazilite rationalism and Hanbalite literalism, using the rationalistic methods championed by Mu'tazilites to defend most tenets of the traditionalist doctrine. Although the mainly Hanbali scholars who rejected this synthesis were in the minority, their emotive, narrative-based approach to faith remained influential among the urban masses in some areas, particularly in Abbasid Baghdad.
