I have never and will never change my name. Majestic, my name is Ana Bint J. as well, but desis regard that as a purely Arab culture, so no point arguing with them that it is just a conjunction and the same thing as a "without bint". Anyway.
In Islam - not in Arab culture only - it is highly prefered that women do NOT change their name. At one place, I have read that it is absolutely forbidden to change their name, but I can't remember the source rite now. It is desi culture, which is paternalistic. The reason women are given the preferance to keep their own name is because the blood lines must have clear identification, otherwise a "Sana bint Fakhri" or "Sana Fakhri" who marries Aamir Saud becomes "Sana Saud" and is in effect on written paper reflected as either his sister or mother, not his wife. In the case that she adopts her husband's first name, she becomes his daughter - on paper. Future generations who have forgotten their ancestry will misinterpret past records, and this causes a great deal of confusion in their lives, marriages, birth, deaths, etc... Esp. when trying to figure out things like if the uncles can marry their sister's nieces or the wife's son can marry the husband's first wife's daughter's neice, etc... It creates a mess.
Blood lines, if you remember, are very important in Islam, that they be kept identifiable and distinct. This is because they give the individual his/her unique identity, and a sense of belonging to a specific tribe. This is the same reason that orphans cannot take on the name of the adoptive-parents, but in fact have to retain their own name, regardless of whether they were found abandoned as an infant with no identiying mark, in which case they are given a name that is separate and distinct from their foster-family's.
Another reason a woman keeps her own name in Islam, is to ensure her welfare and independence. A name is a very powerful symbol of independence. A woman who does not adopt her husband's name, is asserting herself as an individual, who realizes rightfully that her actions and deeds are her own, and she is accountable for them - not her husband. Her husband's duty is limited to providing for her well-being and looking after her, but whatever her deeds or misdeeds are, cannot be ascribed to him. However, they can to a certain extent be ascribed to her own father and mother - since she was brought up by them, and they provided the initial basis for her character and molded her personality in her formative years. It is said that the "sins of the father are revisited upon the children" in the Bible. If you think about it carefully, in Islam it is the other way around.
Another reason a woman keeps her own name, is to give her the power to change her spouses as she wills. This is a freedom that is hers, that no man can take away. She gives her body as a wife, and she gives her caring, love, affection and carries out her duties of caring for her husband whatever they may be, BUT if she chooses to leave the marriage, she is able to do so thru either divorce or khula, and then continue her life with another man, or men if she leaves many marriages, as the case may be. By keeping her name, there is no restriction on her to seek out her own life, after all she is solely responsible for it.
I believe this desi tradition of taking on the husband's name, that is really a paganistic-hand-me-down, is very wrong. Society puts enough pressure on a woman to hold her back from realizing her full potential as an individual, then the pressure from her own family circle, especially the one person who she is most intimately connected with and who is in a way her second half.. this is not to be borne by anyone who cares for the fact that they were born free and will die free, so why the earthly bonds? An ideal husband will not pressure his wife to change her name to his own. This is the test of his own egoism, his tolerance and ability to understand his other half, and treat her with the dignity that another human being merits. After all, if a guest comes to spend the weekend at your home, would you ask him to change his name for the ability to stay in your house and partake of your hospitality and love? All relationships on this earth are temporary, and we all are equal human beings. If the wife takes on the name of the husband, it is only right that the husband be asked to take on the name of his wife.
Yet another reason for the woman keeping her own name, is to keep her linked to her own family even after her marriage. Many - many- desi men are cruel beyond limit in theis regard. They will visit their own parents, but stop the wife from visiting hers. If she calls her family, the men will point to the phone bill. She must first look after the welfare of her in-laws, before giving her own family some attention. This is haraam. Yes, this is another of my fatwas.
The person who stops another from keeping relations with family, kith and kin, is destined for Hell. The gunah of severing relations with people, is immense. Allah SWT has said to treat your parents with respect. The desi men, only take this to be relevant to their own parents. In fact, whether they are the girl's parents or the guy's, both deserve equal respect and gratitude as one's elders. If the girl's parents are in trouble or need assistance, it is incumbent upon the wife to look after her own family matters first, as is the same with the husband. If the wife cannot help her family out in their time of need, the husband should try to assist as well. People in desistan give this co-operation and humble love, the dastardly names of "ghar jamai" or "ghar damad" or "jooru ka ghulam". People who think like this, are beasts themselves.
The same case goes for the man's family. He has to look after his affairs, and if he cannot, his wife may help him. Note, that in the case of the the woman helping the man out - financially, emotionally, spiritually or whatever - it is entirely optional on the part of the woman. In the case of the husband helping his wife out - it is mandatory. She is under his care and protection, her father and guardians entrusted her to his care. He is responsible for her financially, he is responsible for her soundness of mind (unless she is medically proven to be mad), he is responsible for her physical wellbeing, and her spiritual state as well.
This is really a blessing in Islam, that woman can be relatively carefree and happy this way, doing what she wants, as she wants, when she likes. If she is unmarried or has become single again, she is still under the care of her guardians. She may be very brave and bold and advanced, but she is still under someone's caring eye, because while some men may be good, there are others that are not, and she is not in a position to know about all the different sorts out there because men wear a different mask when dealing with a woman than amongst themselves.
Also, if she is an orphan, she is under the care of society - or is supposed to be, but knowing the cut-throats of today, society causes more harm to a woman than good, and this is more because of what woman do to each other than anything else.
It is convoluted Biblical and Judaic traditions that have deviated from their own original path, and paganism infused into modern cultures, that has created syncrenistic values that people follow today.
If u think about why a woman should keep her own name, there are more good reasons for it than you can shake a fist at. :)
