Imam Tahawi's al-Aqidah, representative of the viewpoint of ahl-al-Sunnah wal-Jama'ah, has long been the most widely acclaimed, and indeed indispensable, reference-work on Muslim beliefs. Being a text on Islamic doctrines, this work draws heavily on arguments set forth in the Holy Qur'an and Sunnah.
Likewise, the arguments advanced in refuting the views of sects that have deviated from the Sunnah are also taken from the Holy Qur'an and Sunnah.
It contains references to views of the Shi'ah, Khawarij and such mystics that had departed from the right path. There is an explicit reference in the work to the non-sensical controversy on khalq-al- Qur'an in the times of Ma'mun and some other 'Abbasid Caliphs.
