Apostasy in Islam

< Back to The Qur’an and the Messenger ﷺ

Classical Islamic law prescribes death for apostasy — a Muslim leaving Islam. The ruling is severe, it is plainly present in the sources, and it should not be minimised.

This article examines what the Qur’an prescribes, what the hadith say, and where Muslim scholars have disagreed. That disagreement has existed from the second century of Islam to the present. Presenting the death penalty as an uncontested consensus does not accurately represent the tradition.

The hudud — the severe corporal and capital punishments associated with theft, adultery and other offences — raise a related but separate question, addressed at The Hudud Punishments in Islam.

A note on terms. Ridda means apostasy: a Muslim leaving Islam. Hiraba means armed robbery or brigandage — violent attacks on travellers and communities. It matters here because the one case discussed below in which apostates were executed during the Prophet’s ﷺ lifetime also involved hiraba. A hadith is a report about what the Prophet ﷺ said or did, transmitted through a named chain and assessed for reliability. Sahih al-Bukhari and Sahih Muslim are the most rigorously screened collections. Reports graded da’if are weak and cannot establish a legal ruling by themselves.

The objection

Islam puts people to death for changing their beliefs about God, which is incompatible with freedom of conscience.
This is not a marginal interpretation. It appears in the canonical hadith collections and in all four schools of law.
Muslim-majority states enforce it today, so the harm is current rather than merely historical.

The second point contains the objection’s strongest evidence, but it also overstates the uniformity of the legal tradition. The third point is largely correct and is addressed near the end.

What the Qur’an prescribes

The Qur’an discusses apostasy several times. None of these passages prescribes a worldly punishment. Each places the consequence in the next life.

The main passage says that the apostate’s deeds are lost and that punishment awaits in the hereafter. It goes no further:

“And whoever of you reverts from his religion and dies while he is a disbeliever — for those, their deeds have become worthless in this world and the Hereafter” (Sūrat al-Baqarah 2:217), Saheeh International

﴿وَمَن يَرْتَدِدْ مِنكُمْ عَن دِينِهِۦ فَيَمُتْ وَهُوَ كَافِرٌۭ فَأُو۟لَٰٓئِكَ حَبِطَتْ أَعْمَٰلُهُمْ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ﴾ [سُورَةُ البَقَرَةِ: ٢١٧]
The verse on coerced denial protects a person who recants under duress. It was revealed concerning Ammar ibn Yasir, who denied his faith verbally under torture while remaining a believer in his heart:

“except for one who is forced [to renounce his religion] while his heart is secure in faith” (Sūrat al-Naḥl 16:106), Saheeh International

﴿إِلَّا مَنْ أُكْرِهَ وَقَلْبُهُۥ مُطْمَئِنٌّۢ بِٱلْإِيمَٰنِ﴾ [سُورَةُ النَّحۡلِ: ١٠٦]
Another verse describes a person apostatising, returning, apostatising again, and returning again:

“Indeed, those who have believed then disbelieved, then believed, then disbelieved, and then increased in disbelief — never will Allah forgive them, nor will He guide them to a way.” (Sūrat al-Nisāʾ 4:137), Saheeh International

﴿إِنَّ ٱلَّذِينَ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ٱزْدَادُوا۟ كُفْرًۭا لَّمْ يَكُنِ ٱللَّهُ لِيَغْفِرَ لَهُمْ وَلَا لِيَهْدِيَهُمْ سَبِيلًۢا ۝١٣٧﴾ سُورَةُ النِّسَاءِ

This verse is difficult to reconcile with a rule requiring execution for apostasy itself. A man executed after his first apostasy could never apostatise a second time. Yet the Qur’an expressly describes belief, disbelief, renewed belief, and disbelief again. It assigns the consequence to the hereafter and mentions no worldly punishment.
The Qur’an also states the general principle:

“Let there be no compulsion in religion” (Sūrat al-Baqarah 2:256), Dr. Mustafa Khattab, The Clear Quran

﴿لَآ إِكْرَاهَ فِى ٱلدِّينِ﴾ [سُورَةُ البَقَرَةِ: ٢٥٦]

What the hadith say

The classical position therefore rests on hadith rather than on the Qur’an. Two reports provide its main basis, and their wording is not identical.

The shortest and most frequently quoted text is transmitted through Ibn Abbas. It appears in a report about Ali, the Prophet’s ﷺ cousin and son-in-law, burning a group of zanadiqa — heretics or subversives:

Ibn Abbas said: “Had I been in his place I would not have burnt them, as the Prophet ﷺ said, ‘Do not punish anybody with Allah’s punishment.’ I would have killed them, for the Prophet ﷺ said: ‘Whoever changes his religion, kill him.’” — Sahih al-Bukhari 3017, with fuller wording at 6922¹
The second report lists three cases. Its third item contains a clause absent from the shorter report:

“The blood of a Muslim who testifies that none has the right to be worshipped but Allah and that I am His Messenger cannot be shed except in three cases: in retaliation for murder; a married person who commits adultery; and the one who reverts from Islam and leaves the community.” — Sahih al-Bukhari 6878²

The Arabic of the third clause is al-tarik li-dinihi al-mufariq li’l-jamaʿa — “the one who abandons his religion, separating from the community.” That reference to separation comes from the report itself; it is not a qualification invented by modern apologists. In the most rigorously screened hadith collection, the offence has two parts: leaving the faith and defecting from the polity.
The context of the first report supports the same reading. Ali was dealing with zanadiqa, and Ibn Abbas was discussing how they were executed, not setting out a rule for private unbelief.

Apostasy as political defection

In a seventh-century polity, religious affiliation and political allegiance were not separate categories. Leaving the Muslim community was not simply a change of private belief; it could mean switching sides in a conflict whose sides were defined religiously. Three lines of evidence support reading the reports in this context.

The wars of the ridda concerned state obligations, not private belief. After the Prophet ﷺ died in 632, many Arabian tribes withdrew their allegiance from Medina and stopped paying zakat. Abu Bakr, the first caliph, fought the campaigns known as the ridda wars to preserve the polity. Umar, who became the second caliph two years later, objected that the tribes still professed the testimony of faith. Abu Bakr did not answer that they had ceased to believe in their hearts:

“I swear by God that I will certainly fight those who make a distinction between prayer and zakat, for zakat is what is due from property.” — Sahih Muslim 124; also Sunan Abi Dawud 1556³

The issue here is the refusal to pay a tax owed to the state, not what the tribes privately believed. Umar’s objection rests on the principle that a profession of faith protects a person’s life. Abu Bakr does not deny that principle; he argues that withholding zakat was a separate breach of political obligation. This was a dispute over secession and state revenue among the generation that knew the Prophet ﷺ best.
The one case of apostates executed in his lifetime also involved murder and robbery. The men of Urayna received hospitality, then killed the Prophet’s ﷺ herdsman, stole the camels, and apostatised. The verse revealed about them concerns hiraba, or brigandage, rather than belief:

“Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth to cause corruption is none but that they be killed or crucified, or that their hands and feet be cut off from opposite sides, or that they be exiled from the land.” (Sūrat al-Māʾidah 5:33), Saheeh International

﴿إِنَّمَا جَزَٰٓؤُا۟ ٱلَّذِينَ يُحَارِبُونَ ٱللَّهَ وَرَسُولَهُۥ وَيَسْعَوْنَ فِى ٱلْأَرْضِ فَسَادًا أَن يُقَتَّلُوٓا۟ أَوْ يُصَلَّبُوٓا۟ أَوْ تُقَطَّعَ أَيْدِيهِمْ وَأَرْجُلُهُم مِّنْ خِلَٰفٍ أَوْ يُنفَوْا۟ مِنَ ٱلْأَرْضِ ۚ ذَٰلِكَ لَهُمْ خِزْىٌۭ فِى ٱلدُّنْيَا ۖ وَلَهُمْ فِى ٱلْءَاخِرَةِ عَذَابٌ عَظِيمٌ ۝٣٣﴾ سُورَةُ المَائـِدَةِ

Sunan Abi Dawud 4369 states directly that “the verse regarding fighting against Allah and His Prophet ﷺ was then revealed” about these men. The same incident appears in Sahih Muslim 4353 and Sahih al-Bukhari.⁴ The report therefore identifies the punished offence not as apostasy alone, but as armed predation.
He agreed to return converts from his own side in order to secure a truce. At Hudaybiyya, the 628 truce between the Prophet ﷺ and the Quraysh of Mecca, Suhayl ibn Amr required that anyone coming from Mecca to the Prophet ﷺ be returned to the Quraysh “even if he embraced your religion.” The Muslims strongly objected, but the Prophet ﷺ accepted and honoured the term, returning Abu Jandal after he arrived in fetters.⁵

This is difficult to reconcile with the claim that every departure from Islam was treated as a capital offence. To secure a truce, the Prophet ﷺ accepted and honoured a written term requiring him to return converts to the community they had left, despite strong objections from his own followers.

Where Muslim scholars have actually disagreed

The death penalty was the majority position, but it was not unanimous. The disagreement is early, internal to the tradition, and recorded in standard legal works.

The Hanafi school does not execute women apostates. Its ruling is imprisonment until they return, rather than death.⁶

This exception reveals the reasoning behind the rule. If unbelief itself were the offence, men and women would receive the same punishment. The Hanafi explanation instead turns on women’s status as non-combatants. On that reasoning, fighting, not believing, is what makes the offence capital, and the same principle can extend to other non-combatants.
Ibrahim al-Nakhaʿi (d. 715) and Sufyan al-Thawri (d. 778) were major early jurists; al-Thawri founded a school that did not survive. Both rejected the death penalty and held that the apostate should be invited to repent indefinitely.⁷
Al-Sarakhsi, one of the most authoritative Hanafi jurists, wrote that apostasy and unbelief are grave offences “but they are between the human being and his Lord,” and that their punishment belongs in the hereafter.⁷
Modern scholarship has developed these arguments further. In a book-length study, Taha Jabir al-Alwani argued that neither the Qur’an nor the Sunnah supports a capital penalty for ridda itself, and that the relevant reports concern rebellion against the polity.⁸ In 2007, Ali Gomaa, then Grand Mufti of Egypt, stated publicly that a Muslim who merely rejects the faith faces no worldly punishment because the matter is between the person and God.⁹ Abdullah bin Bayyah has argued that applying an apostasy penalty today is counterproductive because it drives people away from religion.¹⁰

This does not mean that the tradition as a whole has changed its position. The classical majority prescribed death, and that view is still held. The more limited claim is that alternatives did not begin with modern embarrassment. They are recorded as early as the eighth century.

Where the criticism does land

The objection’s third point is largely correct. It cannot be answered by repeating the legal theory.

States apply the death penalty while excluding the disagreement that has always accompanied it. The distinction between private unbelief and political defection, the disagreements among early and modern jurists, and the opportunity to repent made the classical position more contested — and often more restrained in practice — than “kill the apostate” suggests. A state that retains the penalty while suppressing those qualifications is not simply applying a settled tradition. It is choosing the harshest available reading and presenting it as the only one.
Blasphemy and apostasy statutes are used for political purposes, against religious minorities, dissenters and personal enemies. Such uses have little connection to the mufariq li’l-jamaʿa of the hadith and much more to do with local power.
The disagreement described above is often suppressed where the majority position has been codified. Views held by al-Nakhaʿi, al-Thawri and modern muftis are then presented as though they fall outside Islam.

None of this defends those states. The case against their use of apostasy laws can be made from within the Islamic sources, not only from outside them.

Conclusion

The Qur’an prescribes no worldly punishment for apostasy and describes a person apostatising and returning more than once, which execution after the first apostasy would make impossible. The hadith used for the classical ruling include, in the most reliable collection, a clause about separating from the community. The cases in which apostates were executed also involved murder, robbery, or armed secession. Within the legal tradition, the Hanafi exemption for women rests on reasoning concerned with combat rather than belief, while jurists from al-Nakhaʿi in the eighth century to muftis in the twenty-first have argued that the penalty does not apply to belief alone. The death penalty was the majority position. It was not unanimous.
