What is the ruling on a father rejecting a suitor for his daughter due to social and financial reasons? Is it permissible for the daughter to marry without her father's consent? And what is meant by disavowal of lineage (تبرؤ من النسب) and its ruling?

The standard for accepting a marriage proposal should be religiosity and good character. If a young man who is religious and of good character proposes, the father should not reject him. However, if the father insists on refusing, the girl must obey him. Marriage is not valid without the guardian's permission, and he is obligated to marry his daughter off if he finds a suitable match who is religious and of good character. He is not permitted to prevent her from marrying, and if he does so, he sins. The girl has the right to take her case to court to compel him to marry her off. As for the father disowning his daughter, this refers to threatening to boycott and abandon her, but a father cannot deny the lineage of his daughter; she remains his daughter legally. The girl must honor and obey her parents unless they command her to commit a sin or an act that involves excessive hardship or is without benefit.
