While disbelief ( kufr ) is a clear Qur’anic category, the declaration of Takfīr against a professed Muslim is a much graver matter. The Qur’an warns against rash judgments on belief and commands believers to investigate before condemning another who professes Islam [6] .
Likewise, in Islamic jurisprudence, making an unfounded accusation of Takfīr is regarded as a major forbidden act (haram) [7] , and a hadith states that anyone who wrongly declares another Muslim an unbeliever becomes an apostate themselves [8] . Hence, jurists across traditions, including Shia scholars, affirm that Takfīr applies only to those who deny the basic tenets of Islam—not those who differ in interpretation, law, or political stance.
This careful distinction is central to the Shia perspective on Takfīr, which promotes dialogue and understanding instead of condemnation. Historical Background of Takfīr The phenomenon of Takfīr among the People of the Qiblah dates back to the first century AH, shortly after the passing of the Holy Prophet (PBUHH).
During the caliphate of Abū Bakr, some Muslims who rejected his authority, believing that leadership should remain with the Prophet’s Household () [9] were declared unbelievers and rebels. Among them was Mālik ibn Nuwayrah, a devout Muslim who continued to pray but refused to pay zakāt to Abū Bakr’s government [10] . As a result, he and others were accused of apostasy and executed during what became known as the Riddah wars [11] .
During the caliphate of Imam ʿAli (a.s), the Khawārij [12] rebelled after the arbitration at Ṣiffīn, accusing both Imam Ali (a.s) and Muʿāwiyah of disbelief for accepting human judgment in what they claimed was “God’s matter. [13] ” Consequently, they withdrew from the camp of Imam Ali (a.s) and subsequently launched the Battle of Nahrawān against him [14] . The Shia perspective on Takfīr draws heavily from Imam ʿAli’s response to such extremism.
Despite being unjustly accused, Imam ʿAli refused to reciprocate with Takfīr . He treated his opponents as misguided Muslims, not unbelievers, showing patience and restraint. Over time, Takfīr became a political tool used to silence rivals and justify violence. However, the Shia perspective on Takfīr challenges this history by calling for restraint, justice, and humility, reminding Muslims that no political authority or group has the right to monopolize faith.
