Qadariyah
school of Islamic theology, which holds that humans possess free will, whose exercise makes them responsible for their actions, justifying divine punishment and absolving God of responsibility for evil
Qadariyyah (Arabic: قَدَرِيَّة, romanized: Qadariyya), also Qadarites or Kadarites, from qadar (قدر), meaning "power", was originally a derogatory term designating early Islamic theologians who rejected the concept of predestination in Islam, qadr, and asserted that humans possess absolute free will, making them responsible for their actions, justifying divine punishment and absolving God of responsibility for evil in the world. Originally, the Qadarites also reject belief in the prior knowledge of God, and they deny that God wrote the decrees concerning His creation before He created the heavens and the earth; Consequently, their belief goes against the teachings of Sunni Islam. Some of their doctrines were later adopted by the Mu'tazilis and rejected by the Ash'aris. They argued that evil actions of human beings could not be decreed by God, as they would have to be if there was no free will and all events in the universe were determined by God.
Qadariyyah was one of the first philosophical schools in Islam. The earliest document associated with the movement is the pseudoepigraphical text Risala attributed to Hasan al-Basri, which was composed between 75 AH/694 CE and 80/699, though debates about free will in Islam probably predate this text. According to Sunni sources, the Qadariyah were censured by Muhammad himself by being compared to Zoroastrians, who likewise deny predestination.
Sources
The medieval sources upon which information about the Qadariya is based include Risālat al-qadar ilā ʿAbd al-Malik (Epistle to ʿAbd al-Malik against the Predestinarians) which is incorrectly ascribed to Hasan al-Basri; anti-Qadari letters by Hasan ibn Muhammad ibn al-Hanafiyyah and Caliph Umar II; the work of the 9th-century Islamic scholar Khushaysh; the list of Qadarites by Ibn Qutayba, Ibn Hajar, al-Suyuti, Ibn al-Murtada and al-Dhahabi; scattered references to the Qadariya in the work of al-Tabari; and counter-Qadari polemics in the standard hadith collections of Sahih Muslim.
In Sunan Abu Dawood, it is narrated Abdullah ibn Umar that the Prophet said,"The Qadariyyah are the Magians of this community. If they are ill, do not pay a sick visit to them, and if they die, do not attend their funerals."Another report states"To every Ummah there is a magian and the magian of this ummah are those who reject the Qadr.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Qadariyah”, the useful work is to connect “school of Islamic theology, which holds that humans possess free will, whose exercise makes them responsible for their actions, justifying divine punishment and absolving God of responsibility for evil” to the records capable of establishing context and consequence.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jun 27, 2026. The linked authority identifier is Q143069. None of the 0 selected statements returned an explicit reference.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
