Is a girl considered religious and is it recommended to marry her if she is certain of the disapproval of the young man's family regarding her proposal, yet she proceeds with the marriage?

A son must obey his parents in what is good and permissible (ma'ruf), and he should not marry someone they dislike. If a girl knows that the suitor's parents and siblings oppose the marriage, she should not proceed with it, because her acceptance might be considered assisting the suitor in disobeying his parents, which is not permissible, as Allah Almighty says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Her acceptance or rejection of this marriage does not indicate anything about her religiosity or lack thereof.
