Criticism of Islam
Criticism of Islam spans theology, history, and modern human rights.
Last updated
Criticism of Islam has been present since the religion’s early development, with initial objections raised by Jews, Christians, and former Muslims such as Ibn al-Rawandi. Over time, critiques have targeted the life and conduct of Muhammad, including both his public role and personal affairs, as well as the authenticity and moral standing of Islamic scriptures—the Quran and hadiths. Historical practices like the institutional recognition of slavery and the effects of Islamic imperialism on native cultures have also drawn criticism. More recent scrutiny has focused on Islamic doctrines concerning human origins, predestination, and the nature of God, which some critics view as philosophically or scientifically inconsistent.
In modern contexts, criticism often centers on human rights issues in Muslim-majority countries, particularly the application of Sharia law. By 2025, 89 countries worldwide had anti-blasphemy laws, and 22 had anti-apostasy laws; as of 2017, 13 Muslim nations imposed the death penalty for apostasy or blasphemy. Muslim scholars have historically responded through apologetics and theological defenses. Early Christian reactions, such as those by St. John of Damascus, blended theological opposition with political conflict, often misrepresenting Islam as idolatry.
Medieval Christian polemicists treated Islam as a heresy, relying on inherited stereotypes rather than direct study. In the early modern period, thinkers like John Locke questioned whether Muslims could maintain undivided loyalty to a civil state given Islam’s fusion of religious and political authority. Eighteenth- and nineteenth-century European academics often exoticized Islam, using terms like “Mohammedanism” to reduce it to a derivative of Christianity. Meanwhile, medieval Muslim society itself hosted unorthodox critics like Ibn al-Rawandi and al-Ma’arri, whose radical views provoked vigorous rebuttals from theologians and philosophers, reflecting a lively intellectual climate.

Lore & Background
Criticism of Islam has been present since its formative stages, with early expressions made by Jews, Christians, and some former Muslims like Ibn al-Rawandi. Medieval Muslim society also produced unorthodox voices such as Ibn al-Rawandi and Abū Bakr al-Rāzī, whose radical critiques of prophecy provoked rebuttals from theologians and philosophers.
The eleventh-century poet al-Ma'arri was a critic of all religions, believing Islam does not have a monopoly on truth. Apologetic writings attributed to Abd-Allah ibn al-Muqaffa are not widely accepted as established fact, as his known works are translations and political writings. The Jewish philosopher Ibn Kammuna criticized Islam, arguing that Islamic law was less rational than Jewish law, rather than being absolutely incompatible with justice.
Reader's Guide
Criticism of Islam has shaped both interfaith relations and internal Islamic discourse for centuries. Early Christian reactions, such as those by St. John of Damascus, were shaped by theological opposition and political conflict, often favoring aggressive refutation over genuine understanding. During the Middle Ages, Christian church officials commonly represented Islam as a Christian heresy or idolatry, with understanding based more on inherited stereotypes than direct engagement. In the early modern period, thinkers like John Locke raised concerns about political loyalty and religious authority in Islam.
The cultural critic Edward Said argued that Western views of Islam are particularly hostile due to religious, psychological, and political reasons, placing Islam in an inferior position as an object of study. The expansion of Islam has been criticized as spread by the sword, a view opposed by many historians who see it as a multi-faceted phenomenon involving political, social, and economic processes. Muslim scholars have historically responded through apologetics and theological defenses, and the contemporary era sees criticism regarding Muslim immigrants' assimilation in host nations.
