Execution by stoning remains legally authorized in roughly a dozen countries, though carrying it out is rare and several of those jurisdictions operate under formal or informal moratoriums. The penalty is almost always tied to sexual offenses, chiefly adultery by a married person, and the classical evidence rules are so strict that valid convictions are uncommon. When sentences are imposed, appellate courts have overturned them frequently for procedural failures, and major international human rights bodies classify the practice as torture.
What Offenses Trigger a Stoning Sentence
The laws that prescribe stoning target a narrow category of acts classified as zina, meaning sexual intercourse outside a lawful marriage. Severity depends on whether the offender is muhsan: someone who is or has been legally married. A married person convicted of adultery faces stoning. An unmarried person convicted of the same act typically faces one hundred lashes instead.
Several countries extend the penalty to same-sex sexual acts. Yemen’s penal code prescribes stoning for adultery and for homosexual conduct when the offender meets the legal definition of married. Mauritania goes further, prescribing death by public stoning for any adult Muslim man who engages in sexual acts with another man, regardless of marital status.1Immigration and Refugee Board of Canada. Mauritania: The Criminal Code and the Punishment of Same-Sex Sexual Activity
These offenses fall under hudud, meaning crimes with fixed punishments treated as violations of divine law. Because the penalties are considered divinely mandated, judges who find the evidentiary threshold met have limited sentencing discretion.
How the Sentence Is Carried Out
The physical procedure follows a specific protocol, with details varying by jurisdiction. The condemned person is transported to an open area and partially buried in a pit. Men are buried to the waist. Women are buried to the chest, with the stated aim of preventing exposure. That deeper burial also makes it substantially harder for a woman to free herself once the execution begins.
Regulations historically specified the size of the stones. Under the older version of Iran’s Islamic Penal Code, the stones could not be large enough to kill in one or two blows, nor small enough to be ineffective. The stated purpose was to ensure a prolonged process rather than an immediate death. Iran’s revised 2013 penal code no longer includes these procedural details in the same form, though it retains stoning under Article 225.2United Nations Office on Drugs and Crime. Islamic Penal Code of the Islamic Republic of Iran
Classical procedure assigns the first stones based on how the conviction was obtained. When the case rested on witness testimony, the witnesses throw first. When the conviction came from a confession, the judge throws first, followed by the community. The rule forces witnesses or the judge to bear direct personal responsibility for the death, and it creates a final point at which a recantation might occur.
The Escape Rule
One procedural feature carries unusual weight. If the condemned person manages to free themselves from the pit during a stoning based on confession, escape is treated as an implied withdrawal of that confession, and the sentence is halted. The logic is that someone who confessed voluntarily and then fights to live has effectively recanted. When the conviction was based on witness testimony, this rule does not apply, and the execution continues. Yemen’s penal code codifies a version of this principle, listing the offender’s failure to reaffirm a confession before execution as one of several grounds for cancellation of the sentence.
What It Takes to Convict
The evidentiary bar is deliberately extreme, and classical Islamic jurisprudence treats that difficulty as intentional. The primary method of proof requires four adult male eyewitnesses of sound character, each of whom must independently testify that they directly observed the act of penetration. Vague accounts, secondhand knowledge, or testimony about surrounding circumstances do not satisfy the requirement. This standard traces to Surah An-Nur (24:4) of the Quran, which prescribes eighty lashes for anyone who accuses a person of adultery but fails to produce four witnesses.
If even one witness retracts, contradicts the others, or is found to lack the required moral standing, the case collapses. Under the principle of qazf, accusers who cannot meet the four-witness standard may themselves face punishment for false accusation. That creates a powerful structural deterrent against bringing charges at all.
A voluntary confession offers an alternative path, but the classical requirement demands the accused confess four separate times, each time in a sound state of mind and with full awareness of the legal consequences. Judges are actively encouraged to suggest that the accused withdraw the confession, seek reasons to invalidate it, or find legal grounds to avoid imposing the sentence.
Pregnancy as Evidence
Whether pregnancy alone can prove adultery is a genuine point of disagreement among legal schools. The majority position holds that circumstantial evidence, including pregnancy in an unmarried woman, is not sufficient for a hadd conviction. The Maliki school and some Hanbali scholars have historically treated pregnancy as admissible evidence of zina. The disagreement has real consequences. In 2002, appellate courts in Nigeria’s Sokoto and Katsina states overturned lower-court stoning sentences based solely on pregnancy, ruling that pregnancy does not constitute conclusive proof and that due process had been compromised.
Judge’s Knowledge in Iran
Iran’s legal system permits a significant exception to the standard framework. Under the concept of elm-e qazi, meaning the judge’s knowledge, a judge can sentence a defendant to death by stoning based on personal assessment of the case, even when the formal requirements of four witnesses or four confessions have not been met. Human rights organizations have documented cases in which this provision effectively bypassed the safeguards that classical jurisprudence built into the system.
Countries Where Stoning Remains Legal
The gap between statute and enforcement is the defining feature of stoning’s modern legal status. Many countries retain it on the books while rarely or never carrying it out. That matters for the people living under these laws, because a dormant statute can be revived by a willing prosecutor or judge.
Iran
Iran has the most detailed statutory framework. Article 225 of the 2013 Islamic Penal Code prescribes stoning as the fixed punishment for adultery by a married person, with a fallback to execution by other means if stoning “is not possible,” subject to approval by the head of the judiciary.2United Nations Office on Drugs and Crime. Islamic Penal Code of the Islamic Republic of Iran Iran’s judiciary chief issued a moratorium on stoning in 2002, but enforcement has been inconsistent, and sentences continued to be imposed after the moratorium.
Mauritania
Mauritania’s criminal code prescribes stoning for adultery by a married or divorced person under Article 307, and for same-sex sexual acts between men under Article 308.1Immigration and Refugee Board of Canada. Mauritania: The Criminal Code and the Punishment of Same-Sex Sexual Activity The last known execution of any kind following a civil court sentence occurred in 1982, making the law dormant but still active.
Yemen
Yemen’s penal code explicitly lists stoning until death as one of eleven fundamental punishments. Article 263 prescribes stoning for adultery by a married person, and Article 264 extends it to homosexual acts by married individuals. The code sets out specific grounds for cancelling the sentence, including failure of witnesses to begin the stoning after judgment is passed.
Saudi Arabia
Saudi Arabia does not have a single codified penal code in the conventional sense. Its courts operate under uncodified interpretations of Sharia, which permits stoning for adultery. International monitoring organizations report no confirmed recent executions by stoning in the country.
Nigeria
Twelve northern Nigerian states reintegrated Islamic criminal law into their legal systems around 1999 and 2000, formally introducing stoning as a potential sentence.3U.S. Commission on International Religious Freedom. Shari’ah Criminal Law in Northern Nigeria These state-level Sharia codes exist alongside Nigeria’s federal criminal statutes. Several stoning sentences were handed down in the early 2000s, but all documented cases were overturned on appeal.
Pakistan
Pakistan introduced stoning through the Hudood Ordinances of 1979, which prescribed death by stoning for adultery by a married person. The 2006 Protection of Women Act reformed the framework significantly, removing rape from the adultery ordinance, tightening evidentiary requirements to demand four male eyewitnesses, and strengthening penalties for false accusations. No stoning sentence has ever been carried out in Pakistan. Every sentence imposed under the ordinances was overturned on appeal.
Other Jurisdictions
Sudan’s 1991 penal code retains stoning, and as of early 2026 no legislative reform has removed it. Brunei’s Syariah Penal Code Order of 2013 includes stoning for adultery and same-sex acts, but the Sultan extended a moratorium on the death penalty to cover Sharia offenses in 2019, and no executions have been carried out. Qatar and the United Arab Emirates also retain stoning as a theoretical penalty under their legal codes, though documented enforcement is absent.
Appeals and Access to Counsel
The single biggest barrier between a stoning sentence and an actual execution is the appeals process. In Pakistan, every stoning sentence imposed under the Hudood Ordinances has been overturned on appeal. In Nigeria, appellate courts that reviewed the Sokoto and Katsina sentences found fundamental procedural failures in the lower courts. Under Iranian law, death sentences must be appealed within twenty days of the verdict, with confirmed sentences proceeding to the Supreme Court.
Access to counsel at trial is often inadequate. In Iran, defendants in capital cases frequently lack a lawyer during the investigation and interrogation phases, because a restrictive reading of procedural law attaches the right to counsel only after formal charges are filed. Judges can exclude defense lawyers from trial sessions in cases classified as involving “corruption,” and defense attorneys who challenge unfair proceedings risk imprisonment themselves. Language and literacy barriers compound the problem, particularly for women, who are disproportionately affected and are often illiterate or do not speak the court’s official language.
International Law and Human Rights Standards
Article 5 of the Universal Declaration of Human Rights states that no one shall be subjected to torture or to cruel, inhuman, or degrading treatment or punishment. Article 7 of the International Covenant on Civil and Political Rights contains nearly identical language.4Office of the United Nations High Commissioner for Human Rights (OHCHR). International Covenant on Civil and Political Rights Article 6 of the ICCPR adds that in countries that have not abolished the death penalty, it may be imposed only for “the most serious crimes,” which international consensus interprets to exclude adultery and consensual sexual conduct.
The UN Convention Against Torture defines torture as any act by which severe pain or suffering is intentionally inflicted by or with the acquiescence of a public official, for purposes including punishment.5Office of the United Nations High Commissioner for Human Rights (OHCHR). Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment Stoning fits within that definition: it is state-sanctioned, intentionally inflicts prolonged severe pain, and is carried out as punishment. Practical leverage of these frameworks is limited, however. Countries that retain stoning either have not ratified the relevant treaties or assert that domestic religious law supersedes international commitments. The pressure is diplomatic rather than enforceable.
Asylum Protection in the United States
A person facing a stoning sentence in their home country may qualify for protection in the United States under two separate frameworks. The first is asylum. Federal law defines a refugee as someone outside their country of nationality who is unable or unwilling to return because of persecution, or a well-founded fear of persecution, on account of race, religion, nationality, membership in a particular social group, or political opinion.6Office of the Law Revision Counsel. 8 USC 1101 – Definitions A stoning sentence imposed for adultery or same-sex conduct can support a persecution claim on religious grounds or membership in a particular social group, depending on the facts.
To qualify, an applicant must show past persecution or a reasonable possibility of future persecution if returned. An applicant does not need to prove individual targeting if they can establish that the home country has a pattern or practice of persecuting people similarly situated.7eCFR. 8 CFR 208.13 – Establishing Asylum Eligibility Someone who does not qualify for asylum due to disqualifying factors may still be eligible for deferral of removal under the Convention Against Torture, which prevents the United States from returning a person to a country where they are more likely than not to face torture.8eCFR. 8 CFR 1208.17 – Deferral of Removal Under the Convention Against Torture Deferral does not grant permanent immigration status, and it can be terminated if conditions in the home country change, but it prevents deportation to the specific country where the risk exists.
