So in ancient times, people attached great importance to children's surnames, because it represented the continuation of their own families. However, with the development of the times, the progress of society, and the gradual improvement of women's rights and self-awareness, awakened mothers can also have the right to decide whose name their children should be named, and fathers' rights in this regard become less supreme. Personally, I think that as long as the husband and wife can reach an agreement, it is ok for the child to take the mother's surname or the father's surname.
In fact, young people nowadays really don't care so much about surnames and first names. Many people think that this is just a person's symbol, so since you have your own child, give him a symbol or your own blessing. Why do you have to worry about the child's surname? It is not disrespectful whether a child takes his father's surname or respects his mother's surname. As long as both husband and wife agree, it has nothing to do with others, so the most important thing is that both husband and wife reach an agreement.
One more thing, let's be clear. Madina and her husband belong to the middle class of society. They have certain knowledge, education and are not short of money, and their lives are relatively rich. So their understanding of life is fundamentally different from that of some ordinary people. I think the more highly educated people are, the more tolerant they are of their children's surnames.
