My friend is a revert. Someone is ready to marry her but his parents don’t allow him to because they are worried about the social issues that might happen. Therefore is it possible for him to marry her without his parents permission?
Sheikh Ibn Baz and committee of Iftaa said that it is allowed for a man to marry a girl or woman without the approval of his parents. Yet he tries to make them agree in a nice way if possible. If they insist, he can still marry her.
They also commented that even if they were angry from him, this will not harm him. He did not commit a sin by marrying her without their approval.
