Is it permissible to marry a girl who fasts and prays but does not observe the prescribed hijab, and whose father frequently backbites people?

Question:
He asks and says: If I want to propose to a girl who is sixteen years old, and she prays and fasts, and her character is good, but she does not observe the prescribed hijab, and her father frequently backbites people and speaks about their reputations, is it permissible for me to

Answer:
If you hope to teach her the hijab and make her observe it, and she is amenable to this, then there is no harm in marrying her. However, if you see that she will not accept it and that she has become accustomed to this, then it is not permissible for you to marry her while she is not wearing the hijab.
As for the matter of her father backbiting people, this is a great sin from the major sins. It is obligatory to advise him against it, so that perhaps Allah may grant him repentance from this. However, this does not prevent you from marrying his daughter if she is righteous in her religion and herself, and there is nothing in her that prevents marriage to her.
But on the condition that she accepts advice and accepts guidance. If you know that she does not accept advice, does not accept guidance, and that she will continue to leave off the hijab, then it is not permissible for you to marry her. May Allah reward you with good.
