"And those who no longer expect menstruation among your women — if you doubt, then their period is three months, and [also for] those who have not menstruated."
What the verse says
The verse sets the divorce waiting period (iddah) for post-menopausal women at three months and — crucially — sets the same three-month waiting period for women "who have not menstruated." For this legal category to exist and require Quranic regulation, the practice of marrying pre-pubescent girls must be a real and recognized practice, not an edge case. You cannot specify the divorce waiting period for a category that has no members.
Why this is a problem
Classical commentators — al-Tabari, Ibn Kathir, al-Qurtubi — were unanimous in their interpretation: this verse addresses girls too young to have yet reached puberty. There was no controversy about this reading in the classical tradition; it was the plain meaning of the text and was read accordingly. Traditional Islamic law used Q65:4 as foundational evidence that child marriage is lawful under Islamic divine guidance, and it remains operative law in several Muslim-majority jurisdictions where minimum marriage age legislation has been resisted partly on this textual basis.
The Quran could have forbidden child marriage. It did not. It could have been silent about it. It was not. Instead, it codified divorce procedures for it — setting specific waiting periods for pre-pubescent married girls — which provides the religious warrant on which fourteen centuries of Islamic jurisprudence has authorized such marriages. Regulation is not the same as prohibition; regulation implies recognition and acceptance of the practice being regulated as lawful.
Modern attempts to reread "those who have not menstruated" as referring to women with amenorrhea or other medical conditions are post-Enlightenment apologetics with no support in any classical commentary. They require centuries of unanimous Arabic scholars, reading their own language in the context of their own society, to have all misread a straightforward text.
The Muslim response
Contemporary Muslim scholars and organizations, including Musawah and progressive scholars like Kecia Ali, acknowledge the classical reading but argue that the Quran's regulatory approach to marriage must be understood in its historical context, in which child marriage was universal across all ancient and medieval societies, not a practice uniquely endorsed by Islam. The Quran's primary intervention on marriage was to introduce radical protections for women — requiring consent, specifying financial rights (mahr), establishing divorce procedures and maintenance obligations — within a 7th-century context where women had no such legal standing. On the specific reading of "those who have not menstruated," some contemporary scholars, including those associated with the Yaqeen Institute, argue that the verse could encompass women with irregular menstruation or amenorrhea — a medical condition documented in classical medicine — and that the classical consensus, shaped by 7th-century social norms, over-specified the verse's application. More broadly, mainstream Muslim scholars argue that the Quran establishes principles of care, consent, and wellbeing that, properly applied in the modern context through ijtihad, require minimum age of marriage legislation — making legal minimums an application of Quranic ethics rather than a departure from them. The Quran's regulatory framework for a practice it did not invent and could not immediately abolish is presented as gradual reform, not divine endorsement.
Why it fails
Classical Arabic scholars reading their own language in their own cultural context arrived at a single consensus interpretation without controversy: girls who have not reached puberty. The medical-condition reading is a post-Enlightenment apologetic with no traditional support anywhere in the exegetical literature. "Contains rather than authorizes" is a distinction without a practical difference: a divine law that specifies the divorce waiting period for pre-pubescent girls has recognized and formalized their marriage as a lawful category. The Quran had the vocabulary and the capacity to prohibit child marriage; it regulated it instead. That choice has consequences that fourteen centuries of jurisprudence have made visible.
