Is it permissible to marry a girl whom the family rejected due to differences in social class, given the young man's attachment to the girl and his desire for her because of her piety?

The young man is advised to try to persuade his parents to marry the girl he desires, and to seek assistance from those who have influence with them. If the parents insist on refusal without a valid reason, and the young man is in need of marrying her, then there is no sin upon him in marrying her without their consent, and he does not incur sin thereby, unless the parents' refusal is due to valid religious reasons. Nevertheless, he should consider the consequences of this marriage on the relationship with his parents and consult trustworthy individuals. He must also show kindness and dutifulness to his parents in all circumstances.
