Marrying Off Children in Allah's Name: Islam's Age of Consent Issues

In January 2025, Iraq's parliament came within one clause of doing something almost no state had dared to since the mid-twentieth century: writing nine years old into law as an acceptable marriage age for girls. The original amendment to Iraq's Personal Status Law would have let couples opt into rulings from the Jaafari Shia school of jurisprudence, under which girls may marry from age nine and boys from fifteen. Outcry from Amnesty International, Human Rights Watch, and UN child-rights monitors forced a partial retreat — the final text requires religious codes to respect the existing statutory floor of eighteen. But the fight isn't over. Iraqi officials and rights monitors alike expect the nine-year threshold to keep operating quietly, through informal religious marriages that go unregistered until a girl turns eighteen on paper.

That episode isn't an aberration. It's the latest round in a live, ongoing argument inside Islamic jurisprudence over whether a child's marriageability should be governed by a fixed age at all — an argument most other major legal and religious traditions settled, at least in law, generations ago.

The scale of the problem

Globally, an estimated 640 million girls and women alive today were married before their eighteenth birthday, and roughly 12 million more girls are married as children every year, according to UNICEF's most recent figures. Around one in five women aged 20 to 24 worldwide report having married as children. A 2022 report from the ILO, Walk Free, and the International Organization for Migration put the number of people currently in forced marriage — which overlaps heavily with child marriage — at roughly 22 million, with the Arab states showing the highest prevalence relative to population of any region.

Child marriage isn't a Muslim-only phenomenon, and it would be dishonest to claim otherwise: some of the highest rates on record come from Hindu-majority regions and communities in sub-Saharan Africa and Latin America. But that global spread doesn't make the Islamic legal record less worth scrutinizing — if anything, the opposite. Most Christian- and Hindu-majority states settled on a firm statutory marriage age decades or centuries ago; where child marriage persists there today, it persists as an open violation of the law. In large parts of the Muslim world, by contrast, the argument over whether puberty — not age — should govern marriageability is still being fought out in parliaments, sharia courts, and mosque pulpits, in real time, in 2025 and 2026.

What classical Islamic law actually says

The core problem sits in the doctrine itself. No major school of classical Sunni or Shia jurisprudence ever established a fixed chronological minimum age for marriage. Eligibility was instead tied to bulugh — puberty — a standard the four Sunni schools estimated differently: Shafi'i and Hanbali jurists placed it at fifteen lunar years absent earlier physical signs; Hanafi scholars allowed girls to reach it by seventeen; Maliki jurists set the outer bound at eighteen. Crucially, all of them also fixed a minimum age below which puberty could not be assumed regardless of physical development — and for girls, that floor was set at just nine lunar years. Twelver Shia jurisprudence, followed by many Shia Muslims including in Iraq, sets bulugh for girls at nine and for boys at fifteen — the exact provision Iraq's 2025 amendment tried to write into civil law.

Underlying all of this is guardianship. Classical doctrine generally allowed a father, as wali, to contract a marriage on behalf of a daughter who had not yet reached puberty, without requiring her consent — a practice grounded partly in accounts of the Prophet Muhammad's marriage to Aisha, whose betrothal is recorded in the hadith literature at around age six, with the marriage consummated at around age nine. Some modern historians and scholars dispute those specific ages, arguing they sit awkwardly with other evidence about her life, but the traditional account has functioned as legal precedent for over a millennium, and some traditionalist jurists have tied the minimum consummation age directly to it. One partial safeguard did exist in Hanafi doctrine — khiyar al-bulugh, the "option of puberty," letting a girl married off as a minor seek annulment once she came of age if she judged the match unsuitable — but the right had to be exercised promptly, wasn't recognized by every school, and did nothing to stop the marriage, or its consummation, from happening in the first place.

A live argument, not settled history

This isn't a historical curiosity. It's being actively litigated right now.

In Pakistan, a 2023 ruling from the Federal Shariat Court — the country's highest religious court — found that setting a firm minimum marriage age doesn't violate Islamic principles, because Islam requires not just physical puberty but rushd, mental maturity, which takes time to develop. On that reasoning, Pakistan's National Assembly unanimously passed a law in May 2025 banning marriage under eighteen in the Islamabad Capital Territory. Within days, coordinated Friday sermons across Pakistani mosques denounced the law as un-Islamic, provincial governments grew hesitant to copy it, and petitioners returned to the Federal Shariat Court to argue that puberty, not age, should govern marriage eligibility under Islamic law. The country's own top religious court had to rule in favor of protecting children — and clerics are still fighting to overturn it.

In Afghanistan, rights monitors have warned that the Taliban's approach to family law leans on puberty rather than a fixed age as the deciding factor for marriage, unwinding two decades of statutory progress.

And in Iraq, even the watered-down 2025 law still lets couples elect which legal code governs their marriage — civil or religious — which rights groups warn hands religious authorities a route around a statutory age floor that now exists mostly on paper.

Proof that it isn't theological necessity

None of this is inevitable, which is exactly what makes the resistance to reform so hard to excuse. Tunisia banned marriage under eighteen for both sexes in 1956, through Personal Status Code reforms grounded explicitly in reformist Islamic legal reasoning, and today has one of the lowest child marriage rates in the world, around 2 percent. Indonesia — the world's largest Muslim-majority country — raised its minimum marriage age for girls from sixteen to nineteen in 2019. Morocco's 2004 family code reforms raised the marriage age to eighteen, though judicial exceptions still allow younger marriages in practice and remain a target for further reform. These countries prove that nothing in Islamic law compels child marriage; a fixed age, applied without a puberty or guardian escape hatch, is a legislative choice that states and religious authorities are free to make — and, in several cases, already have.

That's what makes Iraq's near-miss and Pakistan's clerical backlash so damning: the alternative isn't hypothetical. It exists, in Muslim-majority, religiously observant countries, right now. Where child marriage persists in the Muslim world, it persists because someone with the power to close the loophole has chosen not to — not because the religion leaves no other option.

What it costs girls

The human cost isn't abstract. UNICEF data link child marriage directly to early pregnancy and elevated maternal and infant mortality, interrupted education, higher risk of domestic violence, and lasting economic disadvantage. A girl married as a child is, by definition, denied the ability to freely consent to the most consequential decision of her life, at an age when she cannot legally sign a contract, vote, or drive in most of the countries where it happens to her.

The reform that's actually needed

The fix isn't complicated, even if the politics are brutal: one statutory marriage age of eighteen, for both sexes, with no puberty exception, no guardian override, and no opt-in to a parallel religious code that sets a lower floor — backed by real civil registration, not left to whichever court or cleric a family chooses to visit. Several Muslim-majority states have already shown this is compatible with a religiously grounded legal system. The question still being fought over in Baghdad's parliament and Pakistan's mosques is whether the rest will follow — or whether clerics and lawmakers keep finding new ways to write nine-year-old brides back into the law.
