early Islāmic history and were known for their neutrality in the dispute between Alī and his opponents after the death of the third caliph, Uthman. By the 10th century CE the term had also come to refer to an Islamic school of speculative theology (kalām) that flourished in Basra and Baghdad (8th–10th century). According to Sunni sources, Muʿtazili theology originated in the eighth century in Basra (now in Iraq) when Wāṣil ibn ʿAṭā' (died 131 AH/748 AD) withdrew (iʿtazala, hence the name Mu'tazila) from the teaching lessons of Hasan al-Basri after a theological dispute regarding the issue of al-Manzilah bayna al-Manzilatayn (a position between two positions), where Wasil ibn Ata reasoned that a grave sinner (fāsiq) could be classed neither as believer nor unbeliever but was in an intermediate position (al-manzilah bayna manzilatayn). The later Mu'tazila school developed an Islamic type of rationalism, partly influenced by Ancient Greek philosophy, based around three fundamental principles: the oneness (Tawhid) and justice (Al-'adl) of God, human freedom of action, and the creation of the Quran. The Muʿtazilites are best known for rejecting the doctrine of the Quran as uncreated and co-eternal with God, asserting that if the Quran is the word of God, he logically "must have preceded his own speech". This went against the orthodox Sunni position which argued that with God being all knowing, his knowledge of the Quran must have been eternal, hence uncreated just like him. Though Muʿtazilis later relied on logic and different aspects of early Islamic philosophy, ancient Greek philosophy, and Indian philosophy, the basics of Islam is their starting point and ultimate reference. Several groups were later influenced by Muʿtazilite theology, such as the Bishriyya, who followed the teachings of Bishr ibn al-Mu'tamir, and the Bahshamiyya, who followed the teachings of Abu Hashim al-Jubba'i. Ashʿarīyyah Ashʿarīyyah is a school of theology that was founded by the Arab Muslim scholar, reformer, and scholastic theologian Abū al-Ḥasan al-Ashʿarī in the 9th–10th century who developed the school of thought founded by Ibn Kullab a century earlier. It established an orthodox guideline based on scriptural authority, rationality, and theological rationalism. As a young man, al-Ashʿarī studied under al-Jubba'i, a renowned teacher of Muʿtazilite theology and philosophy. He was noted for his teachings on atomism, among the earliest Islamic philosophies, and for al-Ashʿarī this was the basis for propagating the view that God created every moment in time and every particle
