DetailInformationClassificationSignificance

SurahAl-KāfirūnMeccanThe absolute distinctiveness of monotheism from polytheism

Key Fiqh IssueIkrāh fī l-dīn coercion to convert to Islam: is it permitted?Ḥarām unanimously prohibitedOne of the clearest cases of unanimous four-school prohibition

School ComparisonAll four schools: coercing conversion to Islam is ḥarām; forced declaration of Islam has no legal effect; the coerced person retains their original religious status; the coercer bears sinUnanimous prohibitionRare case of complete four-school unanimity on a prohibition

Uṣūl Principle"Lā ikrāha fī l-dīn" no compulsion in religion (Qurʾān 2:256) as the foundational principleAbsolute Qurʾānic ruleThe clearest statement of religious liberty in Islamic law

Al-Qurṭubī derives from verse 6 "for you is your religion and for me is my religion" the Qurʾānic foundation for religious distinctiveness and the prohibition on forced conversion. He connects this to Qurʾān 2:256 "there is no compulsion in religion" as the foundational principle. Together, these verses establish that genuine faith cannot be coerced; a forced declaration of belief carries no legal weight as a valid change of religious status.

Al-Qurṭubī applies the ikrāh doctrine: a person who declares Islam under genuine physical or psychological coercion retains their original religious status legally the declaration is null and void. The coercer bears a sin (threatening someone's life or property to force conversion). This does not mean the Islamic state cannot present Islam daʿwah (invitation) is not coercion. The prohibition is specifically on using force, threat, or compulsion to produce a declaration of faith. Al-Qurṭubī also derives from this surah the Islamic epistemological principle: faith is a matter of conviction (yaqīn), not external pressure only genuine internal conviction produces valid iman.

لَكُمْ دِينُكُمْ وَلِيَ دِينِ Lakum dīnukum wa-liya dīn Meaning: "For you is your religion and for me is my religion" Al-Qurṭubī: this verse is the Islamic declaration of religious self-determination; it does not imply that all religions are equally valid (al-Qurṭubī strongly affirms Islam's truth) but that religious conviction cannot be transferred by coercion; the separation between "your dīn" and "my dīn" is categorical.

لَا أَعْبُدُ مَا تَعْبُدُونَ وَلَا أَنتُمْ عَابِدُونَ مَا أَعْبُدُ Lā aʿbudu mā taʿbudūna wa-lā antum ʿābidūna mā aʿbud Meaning: "I do not worship what you worship and you are not worshippers of what I worship" Al-Qurṭubī: the categorical separation establishes that the objects of worship are genuinely different tawḥīd and shirk are not compatible; the religious distinctiveness is real, not merely procedural; al-Qurṭubī derives that interfaith religious syncretism is theologically impossible even if coexistence is legally required.

Coercing conversion to Islam is ḥarām by unanimous consensus of all four schools the "no compulsion in religion" principle (2:256) is absolute.
Forced declaration of Islam under genuine coercion has no legal effect the person retains their original religious status; the coerced declaration is null and void.
The coercer bears sin threatening life or property to produce a religious declaration is a major violation of Islamic law.
Daʿwah (invitation to Islam) is obligatory and permitted the prohibition is on compulsion, not on invitation, education, or persuasion.
Faith is a matter of genuine internal conviction external pressure cannot produce valid iman; only internally convinced faith is spiritually real and legally recognized as a genuine change of religious status.
