Ash'ari

Ash'arism or Ashʿari theology (/æʃəˈriː/;Arabic: الأشعرية‎‎ al-ʾAshʿarīyya or الأشاعرة al-ʾAshāʿira) is an early theological school of Sunni Islam based on clerical authority and rejection of cause and effect reasoning, it was founded by Imam Abu al-Hasan al-Ash'ari (d. 324 AH / 936 AD). The disciples of the school are known as Ash'arites, and the school is also referred to as the Ash'arite school. It is considered one of the orthodox theologies in Sunni Islam alongside the Maturidi.

Amongst the most famous Ash'arites: Al-Bayhaqi, Al-Nawawi, Al-Ghazali, Izz al-Din ibn 'Abd al-Salam, Al-Suyuti, Ibn 'Asakir, Ibn Hajar al-Asqalani, Al-Qurtubi and Al-Subki.

The school arose mainly as a response to the Mu'tazila school of thought and some of their beliefs, although both schools advocated the use of Rationalism in Religion and held the same opinion on the Athari School, some Muslims thought that Mu'tazilizm gave rise to strange and against previously-held opinions. For example, the Mu'tazila believed the Quran to be created, whereas Ash'arites believe that it is uncreated.
