Ash'aris are those who adhere to Imam Abu al-Hasan al-Ash'ari in his school of theology. Ashʿarism or Ashʿarī theology (; : ) is one of the main Sunnī schools of Islamic theology, founded by the Arab Muslim scholar, Shāfiʿī jurist, and scholastic theologian Abū al-Ḥasan al-Ashʿarī in the 9th–10th century. It established an orthodox guideline based on scriptural authority, rationality.

Al-Ashʿarī established a middle way between the doctrines of the Atharī and Muʿtazila schools of Islamic theology, based both on reliance on the sacred scriptures of Islam and theological rationalism concerning the agency and attributes of God. Ashʿarism eventually became the predominant school of theological thought within Sunnī Islam, and is regarded as the single most important school of Islamic theology in the history of Islam.

Two popular sources for Asharism creeds are Maqalat al-Islamiyyin and Ibana'an Usul al-Diyana. Asharism adheres to Theological voluntarism (Divine command theory), thus right and wrong can not be determined intuitively or naturally, since they are not objective realities, but God commands – as revealed in the Quran and the ḥadīth — what is right and wrong. Good is what God commands and is by definition just; evil is what God forbids and is likewise unjust.
