Apostasy (Riddah)

This verse is in a passage (4:88–91) addressing the hypocrites (munafiqun) — people who had nominally converted to Islam but refused to emigrate to Medina when called to do so. The "if they turn away" clause commands killing those who turn back rather than emigrating. Classical jurists applied this verse broadly to anyone who abandons the Muslim community, which they treated as coextensive with apostasy. The verse does not command dialogue, offer, or waiting period — it moves directly from their refusal to the command to kill them wherever found.

The verse is also notable for its explicit instruction not to take any such person "as an ally or helper" — meaning even a survivor is not to be befriended or protected. This absolute social rupture accompanying the death warrant is reflected in classical Islamic law, which holds that an apostate loses all civil rights, including the right to inherit, contract marriage, or own property, upon leaving Islam.

This verse uses the Arabic verb yartadda — the root of riddah (apostasy) — in describing those who turn away from the faith. It is the only Quranic verse that directly uses this vocabulary of apostasy. Notably, it does not prescribe an earthly punishment: it states only that Allah will replace apostates with better believers. The verse's absence of a death command is sometimes cited by Muslim reformers arguing that the death penalty for apostasy has no Quranic basis.

However, the verse describes the replacement believers as "firm with disbelievers" and "struggling in the cause of Allah, fearing no blame from anyone" — qualities that, in context, classical commentators understood as references to military jihad and the willingness to execute judgments without hesitation. Ibn Kathir, interpreting "fearing no blame from anyone," wrote that this referred to their readiness to carry out the prescribed punishment for apostasy even under social pressure not to do so.

This hadith is found in the Book of Jihad section of Sahih al-Bukhari. It reports that Ali ibn Abi Talib (the fourth Caliph) had a group of apostates burned alive. Ibn Abbas criticised the method — burning is reserved for divine punishment — but explicitly confirmed the underlying obligation: they should have been killed, citing the Prophet's direct command. The Arabic man baddala dinahu faqtuluhu translates literally as: "Whoever changes his religion — kill him." This is considered the most direct prophetic statement commanding execution for apostasy.

That Ibn Abbas — one of the most respected companions and Quran interpreters in Islamic tradition — affirmed this ruling without hesitation, and that it is found in the most authoritative hadith collection, gives this narration exceptional weight in classical jurisprudence. All four Sunni legal schools (Hanafi, Maliki, Shafi'i, and Hanbali) cite it as a primary source for the death penalty for apostasy.

This is a parallel narration of the same event (Bukhari 3017 above), placed here in the dedicated Book of Apostates (Kitab Istitabat al-Murtaddin) — a book of Sahih al-Bukhari entirely devoted to the ruling on apostates. The fact that Bukhari included this hadith in both the Book of Jihad and the Book of Apostates indicates its centrality to both domains. The "Zanadiqa" (plural of zindiq) referenced here are heretics or secret disbelievers — a category that includes but is broader than apostates. Regardless, Ibn Abbas affirms the same ruling applies: kill them, using the same prophetic statement.

This hadith is particularly notable for two reasons. First, it does not describe apostates as openly declaring their disbelief — it describes people who "say the best words" but whose "faith will not go beyond their throats." The killing command thus applies to people who outwardly appear to be Muslim but whose sincerity is doubted. This creates a criterion based not on declared apostasy but on suspected insincerity of belief — a category immune to falsification.

Second, unlike most legal commands, this hadith attaches a positive reward for the act of killing: "whoever kills them shall have reward on the Day of Resurrection." The killing is framed not as a regrettable necessity but as a meritorious act. The hadith is also classified under Khawari and Mulhidun (heretics/atheists) in Bukhari's categorisation, indicating it was understood broadly beyond just formal apostasy.

This narration records a specific execution: a man who had converted from Judaism to Islam and then returned to Judaism. Two of the Prophet's most prominent companions, Abu Musa al-Ash'ari (governor of Yemen) and Mu'adh ibn Jabal (one of the most respected scholars among the companions), are both present. The execution is not presented as a judicial matter requiring evidence or appeal — it is carried out after Mu'adh declares "this is the judgment of Allah and His Apostle" three times.

The hadith is also notable for what it does not mention: no trial, no formal accusation, no defence, no attempt to verify the facts of the case beyond Abu Musa's statement, and no option for the man to reconvert. The companion Mu'adh ibn Jabal cites the death judgment as so self-evident that he refuses to even sit down until it is carried out.

A parallel narration of the same Yemen incident from a different chain. This version adds the detail that Abu Musa invited the apostate to return to Islam for approximately twenty days before the execution — a practice known as istitaba (seeking repentance). Classical jurists derived from this the rule that an apostate should be given three days (in some schools) to repent before the sentence is carried out, but that if repentance is refused, execution follows immediately.

The final clause — "he refused, so he was beheaded" — is presented matter-of- factly, without any expression of reluctance or regret. The execution is the uncontroversial outcome of a process whose sole variable was whether the apostate would recant, not whether the punishment itself was appropriate. This narration is found in the Book of Prescribed Punishments (Kitab al-Hudud) of Sunan Abu Dawud, confirming its classification as a hadd (mandatory divine punishment).

This hadith, found in the Call to Prayer section of Sahih al-Bukhari, records Muhammad stating that he seriously considered — and apparently only refrained from carrying out — burning down the homes of Muslim men who did not attend the compulsory congregational prayer (Isha' and Fajr). The men in question are not apostates: they are Muslims who simply failed to attend mosque.

This is included here because it illustrates the broader logic connecting apostasy to the enforcement of Islamic practice: if the Prophet considered burning alive believers for merely skipping prayer, the harsher ruling for those who formally abandon the faith fits within a consistent pattern of violent enforcement of Islamic obligations. Islamic scholars who argue that the apostasy death penalty is not a "real" Islamic ruling must account for the fact that this hadith — threatening arson against Muslims for skipping a single prayer — is in the same collection and is considered equally authentic.

The Reliance of the Traveller is the most widely used classical reference manual for Shafi'i Islamic law in the English-speaking world. The key statements here are: (a) apostasy is the worst form of disbelief; (b) an adult sane apostate deserves to be killed; (c) the state has the obligation to give one chance to repent, then execute; and (d) critically, section o8.4 states there is no legal liability whatsoever for killing an apostate — no blood money (diya), no expiation, no legal remedy — because killing them is just.

The Al-Azhar certification of this text is significant because it means the world's leading Sunni institution validated this ruling as orthodox Islamic law, not as an extremist fringe position. All four Sunni legal schools (Hanafi, Maliki, Shafi'i, Hanbali) agree that a male apostate must be killed; they differ only on procedural details such as whether women apostates are killed or merely imprisoned, and how long the repentance period must be. The ruling is not historical — it remains in force in law codes of several Muslim-majority countries and is the official position of Al-Azhar-certified scholarship.

Section o8.7 of the same manual lists over twenty actions that constitute apostasy, including: reviling Allah or the Prophet, denying the obligatory nature of any pillar of Islam, and — notably — "to be sarcastic about Allah's name, His command, His interdiction, His promise, or His threat." This means that even ironic speech about Islamic obligations, if sincerely meant, qualifies for the death penalty under this legal framework.
