Islam Does NOT Permit Child Marriage

One of the most common polemics against Islam today is that Qur’an 65:4 explicitly permits child marriage. I don't believe the text supports that claim. That conclusion requires moving from what the Qur’an actually says to a particular interpretation of what it means.

The relevant portion of Qur’an 65:4 says:

وَاللَّائِي يَئِسْنَ مِنَ الْمَحِيضِ مِن نِّسَائِكُمْ ... وَاللَّائِي لَمْ يَحِضْنَ

wa-l-lāʾī yaʾisna mina l-maḥīḍi min nisāʾikum ... wa-l-lāʾī lam yaḥiḍna

The verse establishes the waiting period (ʿiddah) following divorce for women whose menstrual circumstances make the ordinary calculation impossible. It first addresses those among “your women” (nisāʾikum) who have ceased menstruating and then adds “and those who have not menstruated” (wa-l-lāʾī lam yaḥiḍna).

That second expression is the center of the controversy.

65:4 Does Not Say “Little Girls”

The Arabic does not say “children,” “little girls,” or even explicitly “prepubescent girls.”

It says:

وَاللَّائِي لَمْ يَحِضْنَ

“and those who have not menstruated.”

That is a description of menstrual status, not an explicit statement of age.

Classical Muslim exegetes certainly interpreted this category as including females who had not menstruated because of young age. That historical fact should not be hidden. Indeed, the classical majority used the verse as evidence that a guardian could contract a marriage involving a minor.

But that is an interpretive inference:

has not menstruated → must be a young child → therefore the verse establishes child marriage.

The first statement does not necessarily produce the second.

A female can reach what her society regards as marriageable age without having experienced menarche.

Historically, Menstruation Could Begin Surprisingly Late

This isn't merely a hypothetical medical possibility.

Modern medical literature reviewing historical European populations estimates that the mean age of menarche in mid-19th-century Europe was approximately 17–18 years old. Improvements in nutrition, hygiene and socioeconomic conditions subsequently contributed to the dramatic decline in menarcheal age seen in modern populations.

Even more strikingly, a large archaeological study of 994 adolescents from medieval England found that although puberty generally began around ages 10–12, menarche occurred around 15 for much of the sample and approximately 17 among females living in medieval London. Researchers identified poor nutrition, infection and physical exertion as probable contributors to delayed maturation.

Historical research also demonstrates a relationship between food availability and menarcheal age.

Think about what that means.

If the average woman in a particular historical population experienced her first menstruation around 17, there necessarily existed women who menstruated considerably later.

Therefore, a female who “has not menstruated” is not necessarily synonymous with a small child.

That doesn't prove that Qur’an 65:4 was referring exclusively to older women with delayed menarche. But it does defeat the claim that the Arabic expression itself can only mean a prepubescent child.

The Verse Presupposes Marriage—but Does Not Tell Us the Woman's Age

There is one thing about the classical argument that is correct: because 65:4 concerns ʿiddah following divorce, the women being discussed were married.

But that only establishes:

married + has not menstruated.

It doesn't independently establish:

married + is a little girl.

Age has been supplied through interpretation.

And historically we know that the first category does not necessarily imply the second.

Was Child Marriage Normative in Muhammad's Arabia?

Another claim frequently slipped into the discussion is that marrying prepubescent girls was simply normal behavior among seventh-century Arabs.

That assertion goes beyond our evidence.

We do not possess anything resembling a marriage census for seventh-century Arabia from which we can calculate the typical age of brides or determine what percentage of marriages involved prepubescent females.

There is evidence that early Islamic jurisprudence recognized minor marriage, and later Islamic law extensively discussed it. But legal recognition is not evidence of statistical normativity.

Something can be legally possible without being the ordinary behavior of a society.

Therefore, I would not argue that we can prove prepubescent marriage never happened in Muhammad's Arabia. We plainly cannot.

My argument is narrower:

We cannot demonstrate that marriage to prepubescent children was the normative marriage practice of Muhammad's society merely by citing Qur’an 65:4.

Early Muslim Jurists Themselves Rejected Minor Marriage

There's another serious problem with presenting the permissibility of child marriage as the only possible Islamic understanding.

Early Muslim jurists including Ibn Shubruma and Abū Bakr al-Aṣamm are reported as rejecting the authority to marry off a minor before maturity. Their reasoning was associated particularly with Qur’an 4:6:

حَتَّىٰ إِذَا بَلَغُوا النِّكَاحَ

“until they reach marriageable age.”

Their argument treated “reaching marriageability” as something that occurs as the child emerges from minority.

ʿUthmān al-Battī is likewise reported in later juristic literature as rejecting a guardian's authority to contract such a marriage for a minor.

Later majority jurists responded to this minority position by invoking 65:4: if someone who had not menstruated possessed an ʿiddah, they reasoned, she must previously have been capable of marriage.

But notice what this establishes historically.

The permissibility of minor marriage was a juristic dispute.

If 65:4 simply and unambiguously meant:

«“Allah permits Muslims to marry prepubescent children,”»

it becomes considerably harder to explain why early Muslim jurists could deny precisely that legal proposition.

We should therefore distinguish between the Qur’anic text itself and the jurisprudential conclusions later scholars derived from it.

Contemporary Islamic Scholarship Can Prohibit It

This distinction isn't confined to modern secular reformers.

Egypt's Dar al-Ifta, one of Sunni Islam's major contemporary fatwa institutions, explicitly states that the position adopted in contemporary Egypt is to prohibit minor marriage religiously and legally.

Its 2022 treatment specifically invokes the earlier positions of Ibn Shubruma and al-Aṣamm. It goes further and adopts the position that these harmful minor-marriage contracts are invalid, grounding that conclusion in Islamic jurisprudence, the purposes of marriage, human dignity and the prevention of established harm.

Dar al-Ifta has also called for the criminalization of exploitative marriages involving minors, arguing that such arrangements violate the Islamic conception of marriage as an institution of mercy, dignity, compatibility and mutual respect.

Importantly, Dar al-Ifta openly acknowledges that the classical majority interpreted 65:4 as supporting the permissibility of a guardian contracting a prepubescent marriage. It therefore isn't pretending that the classical interpretation never existed.

Rather, contemporary Islamic jurisprudence demonstrates that the classical majority interpretation does not prevent Muslim jurists from reaching a prohibitionist position through Islamic law itself.

Muslim-Majority Countries Have Legally Restricted Child Marriage

We can see the same development in law.

Egypt

Egypt establishes 18 as the legal marriage age. Egyptian law does not permit official solemnization of marriages below that age.

Dar al-Ifta has explicitly supported efforts against underage marriage and grounds that opposition in Islamic as well as legal principles.

Saudi Arabia

Saudi Arabia is particularly significant because its Personal Status Law is explicitly situated within an Islamic legal system.

Article 9 provides that marriage contracts involving someone under 18 may not ordinarily be documented. However, accuracy requires an important qualification: Saudi Arabia does not impose an absolute under-18 ban. A court can authorize an under-18 marriage if the person has reached puberty and the court determines that the marriage serves that person's interests.

So Saudi Arabia is better described as establishing 18 as the presumptive legal minimum with a judicial exception, not as categorically banning every marriage under 18.

Indonesia

Indonesia—the world's largest Muslim-majority country—changed its marriage law in 2019.

Law No. 16 of 2019 establishes:

19 years old for both men and women.

The Indonesian government explicitly explained that raising the age was intended to protect children's development, education and health and reduce harms associated with early marriage.

Again, there is a qualification: Indonesian courts retain authority to grant dispensations in urgent circumstances.

The significance remains obvious: major Muslim societies have concluded that restricting marriage by age is entirely compatible with their legal and Islamic frameworks.

What 65:4 Actually Establishes

None of this requires rewriting Islamic history.

The classical majority interpretation existed.

Prepubescent marriage existed.

Muslim jurists developed rules governing it.

And child marriage unfortunately continues to exist in parts of the Muslim world, just as it exists in non-Muslim societies.

But none of those facts transforms the words:

“those who have not menstruated”

into:

“little girls whom Islam tells Muslims they may marry.”

Those are not equivalent statements.

The Qur’an describes a category of married females whose menstruation cannot be used to calculate the ordinary waiting period. Classical scholars interpreted that category as including young girls. Other early jurists nevertheless rejected contracting marriages for minors. Historical evidence demonstrates that females could reach remarkably late ages without experiencing menarche. Contemporary Muslim jurists have used Islamic jurisprudence itself to prohibit minor marriage, while Muslim-majority governments have established statutory marriage ages.

The most historically responsible conclusion is therefore more nuanced:

Qur’an 65:4 regulates divorce and establishes an ʿiddah for females who have not menstruated. It does not explicitly identify those females as children, does not specify their ages, does not command child marriage, and does not establish that prepubescent marriage was normative in Muhammad's society.

The classical majority's inference that the verse encompasses prepubescent wives is an important part of Islamic legal history.

But an interpretation of a verse is not the vocabulary of the verse itself.

That distinction is exactly what the polemic usually erases.
