"Why does a woman's surname change when she marries? Is this in Islam?" This question is one of those topics where modern law and Islamic law are confused with one another. Many people assume that a woman taking her husband's surname is a religious obligation. In truth, what Islam upholds is the preservation of lineage (nasab).
The DuaMio Wisdom approach here does the following: first it clarifies the ruling, then it shows the context, and then it carries the wisdom into a language today's reader can understand.
Short answer: In Islam, lineage does not change
In Islam, marriage is not a transfer of ownership; it is a lawful contract established between two parties. When a woman marries, she is not severed from her father's lineage, nor does she pass into her husband's lineage. Marriage does not transfer a woman's identity into the ownership of the man.
The ruling layer: Al-Ahzab 5 and the principle of nasab
The Qur'an commands that everyone be attributed to their true father; this principle shows that lineage and nasab cannot be altered:
"Call them by [the names of] their fathers; it is more just in the sight of Allah. But if you do not know their fathers - then they are [still] your brothers in religion and those entrusted to you. And there is no blame upon you for that in which you have erred but [only for] what your hearts intended. And ever is Allah Forgiving and Merciful."
- From Surah Al-Ahzab, verse 5 (Sahih International - quran.com)
This principle applies to marriage as well, because marriage does not change biological origin. A woman continues to be the owner of her own family, her own nasab, and her own identity.
Examples from history: a woman is known by her father's name
In the Age of Bliss (Asr al-Sa'ada), women continued to be known - even after marriage - not by their husbands' names but always by their fathers': Aisha bint Abi Bakr (Aisha, daughter of Abu Bakr), Hafsa bint Umar, Khadija bint Khuwaylid, and the Prophet's daughter Fatimah az-Zahra bint Muhammad. Even after Fatimah married Ali ibn Abi Talib (may Allah be pleased with him), she was never called "bint Ali" but was always known as "bint Muhammad" or, in reference to her father, as "bintu Rasulillah" (the daughter of the Messenger of Allah). This naming practice is the clearest historical evidence that marriage does not alter a woman's lineage.
The context layer: Surname change is of Western origin
A woman taking her husband's surname on marriage is a product not of Islam but of Western culture. In old Roman and Western law, a woman largely lost her legal independence upon marriage and was treated almost as her husband's "property" (the doctrine of coverture in English common law); for this reason her former identity was erased and she took the man's surname. Islam, by contrast, has never regarded a woman as the property of a man and has recognised her as an independent legal person. The surname practice in Turkey likewise entered the legal system through the 1934 Surname Law and the Turkish Civil Code, which was adapted from the Swiss Civil Code. For this reason, saying "a woman must take her husband's surname because Islam requires it" is simply not correct.
The wisdom layer: A woman's identity is preserved
Islam does not view a woman as an extension or property of a man. Before and after marriage, a woman is an independent legal personality: she can own property, inherit, receive her mahr, and manage her own earnings. The preservation of her lineage is part of this independent identity.
Why is the preservation of nasab important?
Among the five essential aims that Islamic law protects (maqasid al-shari'a), the preservation of lineage (hifz al-nasab) is one. Nasab safeguards family bonds, inheritance law, the boundaries of mahram relations, and a person's knowledge of their own roots. Erasing or altering a person's true lineage can throw family law into disarray. For this reason, in Islam lineage is not seen as a label to be changed for administrative convenience or on the occasion of marriage. Ascribing oneself to someone else's lineage was warned against by the Prophet in the gravest terms:
"Paradise is forbidden to the one who ascribes himself to someone other than his father."
- Bukhari, Fara'id 29 (no. 6768); Muslim, Iman 63 (no. 63) - from Sa'd ibn Abi Waqqas (Muttafaqun alayh, sahih)
This hadith shows that changing one's lineage is not merely a matter of a name but a serious violation of rights. A woman changing her surname on marriage does not, of course, fall within the scope of this severe warning; the hadith concerns the intention of cutting oneself off from one's true father and ascribing oneself to another. Even so, the same principle reminds us of this: Islam considers lineage a trust, not a label to be changed lightly.
Practice in Muslim-majority countries
Today, in many Muslim-majority countries (Saudi Arabia, Egypt, Morocco, Indonesia and others), women continue to use their own surnames after marriage; this is consistent with Islam's understanding of nasab. A woman keeping her surname is therefore not a modern act of rebellion but a practice closer to Islam's deep-rooted principle of lineage.
Seeing the measure clearly
At the heart of the matter is this: Islam does not transfer a woman's identity into a man's ownership through the marriage contract; the tie of lineage is by birth, and a woman is not severed from that tie when she marries. The Qur'an directly commands the preservation of lineage by saying "Call them by [the names of] their fathers" (Al-Ahzab 5); the practice of the Age of Bliss makes this principle concrete: Aisha bint Abi Bakr, Hafsa bint Umar, Khadija bint Khuwaylid, and Fatimah bint Muhammad continued to be known by reference to their own fathers even after marriage. The Western-origin practice of "taking the husband's surname" comes from the doctrine of coverture and modern civil codes; it carries the imprint of Western law, not of Islam. A woman preserving her own surname is therefore not a modern rebellion but a natural extension of a right that Islam recognised fourteen centuries ago. The issue is not merely a registry entry; it is about protecting who a person is, from what roots they come, and to which family they are entrusted.
Summary
In Islam, a woman is not required to change her surname on marriage. She remains bound to her father's lineage. Marriage does not make a woman the property of the man; it does not extinguish her identity, her ownership, or her legal personality.
The question is not: "Should a woman take her husband's surname when she marries?"
The real question is:
"Is a woman preserving her own name, her lineage, and her identity a modern act of rebellion, or a right that Islam recognised fourteen centuries ago?"
