The short answer #

Sharia is Islamic law: a complete legal system covering worship, family life, commerce, crime, war and government. Its classical rules punish leaving Islam with death, give women half the inheritance and, in financial matters, half the testimony of men, let men but not women divorce at will, and place non-Muslims in a lower legal status. Where it is state law today, it produces the world's highest execution rates, public floggings and death sentences for blasphemy. Europe's human-rights court has ruled that a regime based on Sharia "clearly diverges from Convention values."

Britain is the case study. Sharia has no legal jurisdiction there, yet it operates informally and at scale: through Sharia councils the government does not count or regulate, arbitration tribunals, and religious marriages that leave wives without legal protection. The government's own review found that "no one disputed that sharia councils engage in practices which are discriminatory to women." In the most recent poll, 32% of British Muslims said Sharia in the UK would be desirable.

Sharia around the world #

  • Executions. Iran and Saudi Arabia, both Sharia-based states, carried out about 93% of the world's recorded executions in 2025: 2,159 and 356 respectively.1
  • Afghanistan. The Taliban publicly flogged at least 1,110 people in 2025, banned girls from secondary school, and in 2024 made it illegal for women's voices to be heard in public.2
  • Blasphemy and apostasy. Twelve countries provide for the death penalty for blasphemy or apostasy.3 In Pakistan, 104 people were killed by mobs or vigilantes after blasphemy accusations between 1994 and 2024.4
  • Homosexuality. Six Sharia-based jurisdictions prescribe death for consensual same-sex acts: Brunei, Iran, Mauritania, northern Nigeria, Saudi Arabia and Yemen.5
  • Public support. Pew's survey of 39 countries found 84% of Pakistani Muslims and 74% of Egyptian Muslims want Sharia as official law. Among those supporters, 76% in Pakistan and 86% in Egypt back death for leaving Islam. In Turkey, only 12% wanted Sharia.6

What classical Sharia requires #

  1. Death for apostasy. "Whoever changed his Islamic religion, then kill him" (Sahih al-Bukhari 6922). All the classical schools agreed.
  2. Physical punishments. Amputation for theft (Quran 5:38), 100 lashes for sex outside marriage (Quran 24:2), and stoning for adultery by a married person (from hadith).
  3. Unequal rights for women. Two women's testimony equals one man's in financial matters (Quran 2:282); a daughter inherits half a son's share (Quran 4:11); a husband may divorce by declaration.
  4. Subordination of non-Muslims. Quran 9:29 orders fighting Jews and Christians "until they give the jizyah willingly while they are humbled."
  5. Expansion by war. Classical law divided the world into the "abode of Islam" and the "abode of war". A hadith in Sahih Muslim (1731) tells commanders to offer enemies Islam, then the jizya tax, and if both are refused, to "fight them." Some modern scholars say this no longer applies. Islamists reject that view.

Britain: the case study #

  • Sharia councils. The government "does not hold data on the number of sharia councils… and there is no plan to produce such data" (March 2026). About 30–35 formal councils can be identified. The often-quoted figure of 85 dates from 2009 and includes informal mosque and online services. The true number is unknown and probably higher.7
  • Harm. The Casey Review (2016) reported councils "condoning wife-beating, ignoring marital rape and allowing forced marriage", and women pressured "to return to abusive partners."8 BBC Panorama filmed a scholar telling an abuse victim that the police were a "last resort."
  • Unregistered marriages. 61% of Muslim women in religious marriages surveyed by Channel 4 had only a nikah, with no legal protection. In 2020 the Court of Appeal held that an 18-year nikah marriage with four children was no marriage at all.9
  • Child marriage. ITV found 18 of 56 mosques contacted willing to arrange the marriage of a 14-year-old (2013).
  • Sharia in public space. "Sharia controlled zone" stickers (2011) and a "Muslim Patrol" that harassed drinkers, couples and women (2013) were prosecuted. The chief inspector of police described communities "where the police never go because they are never called." A teacher accused of blasphemy has been in hiding since 2021, and a government review found he was "totally and utterly failed."10
  • Public opinion. Polls from 2006 to 2024 found between 23% and 43% of British Muslims supporting some form of Sharia in Britain.11

Pros and cons #

Arguments made for accommodating Sharia Arguments against
Religious freedom: many Muslim women need a religious divorce The divorce system is unequal in structure, not just in bad practice
Use is voluntary; councils have no legal power Family and community pressure means "voluntary" is often not free
Jewish and Catholic tribunals operate similarly Parliament fixed the Jewish divorce problem in 2002; the Islamic one remains
A ban would drive councils underground Councils are unregulated and uncounted, with no safeguarding duty
Islamic finance brings investment Unregistered marriages strip women of legal protection
Each accommodation signals a rival source of law, which a third of British Muslims say they would welcome

Our assessment. Classical Sharia is not compatible with a modern democracy. Where it is state law it produces mass executions, flogging, and the legal subordination of women and religious minorities. In Britain it harms women even without legal power, and the state has chosen not to measure or regulate it. The answer is one law for everyone, enforced: compulsory civil registration of every marriage, equality law applied to every tribunal, an official count of councils, and absolute protection for free speech.

Claims and evidence #

  • "Classical Sharia punishes apostasy with death." True.
  • "Sharia councils are harmless." False. The government's own review found discrimination.
  • "There are only about 30 councils." Understated. The real number is unknown and probably higher.
  • "Britain has Sharia law." Not legally. In practice, Sharia operates informally through councils and religious marriages.
  • "There are Sharia no-go zones." Partly true. Sharia patrols and intimidation are documented. No area has been shown to be legally under Sharia or closed to police.
  • "Most British Muslims want Sharia." No, but a large minority do: 23% to 43% across polls.

The full research file has every claim sourced, with 135 numbered sources. A separate page, The Quran on war, quotes 71 passages in full, including the verses terrorists cite most.

Method and corrections #

How this site works. Every factual claim carries a numbered source. We rely on, in order:

  1. primary texts: the Quran in Pickthall's translation with the Arabic original (a few quotations on the summary and research pages use the Sahih International translation, and are marked as such), and hadith by collection and number;
  2. court judgments and official reviews;
  3. national statistics and international bodies;
  4. named polling organisations, with their samples and methods;
  5. recognised academic historians.

Where scholars disagree, we say so and name both sides. Where a popular claim fails checking, we say that too, including claims that support our argument.

What we criticise. We criticise laws, doctrines, ideologies and institutions: Sharia as a legal system, and Islamism as a political movement. We do not attack people for their faith. Most Muslims are not Islamists, and many are Islamism's first victims.
