Thank you for your help and clarification.
Praise be to Allaah.
The effects of imitating the west in naming ourselves are many. One of them is the way in which people have got used to omitting the word ibn (son of) or ibnatu (daughter of) between their own names and the name of their fathers. The reason for this is, firstly, because some families have adopted children and given them their surname, so that the adopted child is called Foolaan Foolan [where Foolaan (=So and so) stands for a name] and their real children are called Foolaan ibn Foolaan (So and so the son of So and so). Now in the fourteenth century AH, people have dropped the word ibn or ibnatu which is unacceptable according to linguistics, custom and shareeah. May Allaah help us.
Another effect is the habit of women taking their husbands surnames.
Originally, the woman is So and so the Daughter of So and so, not So and so the wife of So and so! Allaah says (interpretation of the meaning):
Call them (adopted sons) by (the names of) their fathers, that is more just with Allaah [al-Ahzaab 33:5].
As it is in this world, so it will also be in the Hereafter, as the Prophet (peace and blessings of Allaah be upon him) said:
On the Day of Resurrection, each betrayer will have a banner raised beside him, and it will be said, this is the betrayer of So and so the son of So and so. (Narrated by al-Bukhaari, 5709, and Muslim, 3265).
Shaykh Bakr Abu Zayd (may Allaah preserve him) said: This is one of the beauties of shareeah, because calling a person by his fathers name is more appropriate for knowing who is who and telling people apart. The father is the protector and maintainer of the child and his mother both inside and outside the home. This is why the father mixes with people in the marketplaces and takes risks by travelling to earn a halaal living and strive for their sakes. So the child is given the name of the father, not of the mother who is hidden away and who is one of those whom Allaah commanded (interpretation of the meaning):
And stay in your houses [al-Ahzaab 33:33]
(Tasmiyat al-Mawlood, 30, 31).
On the basis of the above, there is no blood tie between the husband and wife, so how can she take his surname as if she is part of the same lineage? Moreover, she may get divorced, or her husband may die, and she may marry another man. Will she keep changing her surname every time she marries another man? Furthermore, there are rulings attached to her being named after her father, which have to do with inheritance, spending and who is a mahram, etc. Taking her husbands surname overlooks all that. The husband is named after his own father, and what does she have to do with the lineage of her husbands father? This goes against common sense and true facts. The husband has nothing that makes him better than his wife so that she should take his surname, whilst he takes his fathers name.
Hence everyone who has gone against this and taken her husbands name should put matters right. We ask Allaah to put all the affairs of the Muslims right.
