It's assumed, almost everywhere in the English-speaking world, that a woman takes her husband's surname when she marries. It's assumed so completely that many people โ including many Muslims โ take it for granted as simply how marriage works, full stop. It isn't. It is a specific custom from a specific legal tradition, and Islam has never required it. If anything, the Qur'an points the other way.
The starting point is a direct Qur'anic instruction, revealed in a moment when the question of whose name a person carries had real consequences. Before this revelation, it had become customary in Arabia for an adopted child to take the name of the adoptive father, blurring their actual lineage. Allah corrected this directly:
ุงุฏูุนููููู ู ููุขุจูุงุฆูููู ู ูููู ุฃูููุณูุทู ุนูููุฏู ุงูููููู
"Call them by [the names of] their fathers; it is more just in the sight of Allah."
Surah Al-Ahzab, 33:5
The principle is about truthfulness in lineage (nasab): a person's name should reflect their real parentage, because getting that wrong isn't a small administrative matter in Islamic law โ it's tied to inheritance rights, to who may or may not be a mahram (a person permitted to be alone with, or forbidden from marrying), and to honest record-keeping across generations. Contemporary scholars applying this principle to modern marriage are consistent on the conclusion: a wife has no blood relationship to her husband, so adopting his family name isn't a small tidiness choice โ it manufactures exactly the kind of false lineage attribution the verse was revealed to correct. Rulings on this point (see references below) also note the practical problem it creates: a woman who remarries after widowhood or divorce would need to keep changing her name to match each husband, unmooring her identity from anything stable across her own life. Even more lenient contemporary fatwas โ which permit a social-use surname purely for identification purposes โ still affirm that a woman's actual nasab to her father never changes and must still be acknowledged, regardless of what name she uses day to day.
The naming convention used throughout early Islamic history for the Prophet's family and companions makes the point better than any ruling can. Every woman close to the Prophet ๏ทบ was known by her own father's name, for her entire life, marriage included:
This is the uncontested norm across all four Sunni schools of law and Shia jurisprudence alike. No classical school of Islamic law records wives taking their husbands' family names. It simply isn't part of the tradition.
It comes from English common law โ specifically, from a doctrine called coverture. Under coverture, which developed in medieval England and was carried into American law, a married woman's legal existence was considered absorbed into her husband's. The 18th-century jurist William Blackstone, whose Commentaries on the Laws of England shaped Anglo-American law for two centuries, put it plainly:
"By marriage, the husband and wife are one person in law: that is, the very being or legal existence of the woman is suspended during the marriage, or at least is incorporated and consolidated into that of the husband."
William Blackstone, Commentaries on the Laws of England, 1765โ69
This wasn't a poetic metaphor. Under coverture, a married woman could not independently own property โ it transferred to her husband. She could not sign contracts in her own name. She could not sue or be sued as herself. Her wages, if she worked, legally belonged to him. For centuries, this legal framework was even used to hold that a husband could not be found guilty of raping his wife, because she was deemed to have no separate legal personhood from which consent could meaningfully be withheld or given. Taking the husband's surname was the everyday, visible symbol of this legal merger โ a public marker that a woman's separate legal identity had, in the eyes of the law, ceased to exist.
This is not ancient history. Reform came late and slowly: England's Married Women's Property Acts of 1870 and 1882 began dismantling the property provisions. In the United States, individual states passed their own reforms through the 19th and 20th centuries, and the U.S. Supreme Court only described coverture as "obsolete" in 1966 โ while acknowledging it still lingered in several states at that time. Louisiana was the last U.S. state to repeal its "Head and Master" law, in 1979, meaning the legal machinery behind this naming custom was still operating in parts of America within living memory.
The contrast is the point. Islamic marriage, from its earliest legal formulations, treats husband and wife as two separate legal persons joined by a contract โ each retaining their own property, their own right to sue and be sued, their own name, their own lineage. Coverture treated marriage as the legal disappearance of the wife into the husband. A wife keeping her own name in Islam isn't a modern feminist adaptation of the faith. It's the original position โ one that predates, by centuries, the Western legal reforms that eventually caught up to it.
Beyond its legal origins, there's a growing, legitimate body of research on the practical and psychological weight of the surname-change custom โ the very custom Islamic practice avoided from the outset.
Sociological research has documented a real social penalty specifically aimed at women who keep their birth name: studies summarized by sociologist Elizabeth Aura McClintock (University of Notre Dame) show women who don't change their name are perceived by others as "selfish and uncommitted to their marriage and family" โ a judgment that, tellingly, is never applied to a man who keeps his own name, because for him that's simply assumed. One study found that as recently as a generation ago, over 98% of American women took their husband's name at marriage; even now it remains the overwhelming majority practice, sustained less by free personal choice than by strong social expectation.
A 2021 peer-reviewed study in Frontiers in Psychology, surveying women across Turkey and the United States, found something worth sitting with: support for a wife changing her surname was significantly predicted by hostile sexism โ even among women who identified as feminist. The researchers concluded that marital surname change functions as a marker tied to an "antiquated conception of gender relations defined through male domination," not a neutral tradition.
There are also concrete, everyday costs. Women who have built a professional reputation, publications, or credentials under their birth name risk fragmenting that record โ losing the thread between years of prior work and their post-marriage identity. A 2024 Fortune report found a meaningful and growing share of younger professional women now keep their name specifically to protect their career record, alongside privacy and safety concerns tied to being findable online under a changed name.
It's also worth being clear that this isn't a uniquely Islamic-versus-Western question โ plenty of non-Muslim-majority countries never adopted the English custom either. In Quebec, women have been legally barred from taking a husband's surname since 1981. France has required a person's legal name to remain their birth name since 1789 (a husband's name may be used socially, but never legally). Greece, Italy, Belgium, and the Netherlands all have similar retention norms. Across Spain and most Spanish-speaking Latin American countries, women keep their own paternal surname for life as a matter of course. The English/American custom of a wife erasing her name into her husband's is, in the fuller global picture, the outlier โ not the default.
None of this is a judgment on any woman's personal choice โ plenty of women choose to change their name for reasons that are entirely their own, and that's their right. The point is simpler: it's not an Islamic requirement, it never was, and treating it as one gets the history backwards. A Muslim woman who keeps her own name after marriage isn't departing from tradition. She's the one actually observing it.
