Wants to marry a
    girl but his father does not approve of her
Question

                I have chosen a religious and
      well-mannered girl to be my wife, but when I told my father about this, he rejected the
      idea. I have tried to convince him but he is insisting. I wanted to know why, but he said
      there is no reason why. I am confused. Should I obey my father and forget about the girl I
      have chosen even though this will cause me and my family so much pain? I hope that you
      will advise of the right thing to do. May Allaah reward you with good.
Praise be to Allah.This question requires that we offer advice to both of you. Firstly, to
    your father, who you say is preventing you from marrying this girl whom you describe as
    religious and well-mannered. He has to allow you to marry her, unless he has some
    legitimate Islamic reason, which he should explain to you to convince you and put your
    mind at rest. He should also put himself in your shoes: if his own father prevented him
    from marrying a religious and well-mannered girl whom he liked, would he not feel
    resentful about this denial of his freedom? If he would not like his father to do such a
    thing to him, how can he do this to his son? As the Prophet 
 (peace and blessings of
    Allaah be upon him) said: “None of you truly believes until he likes for his brother
    what he likes for himself.”
It is not right for your father to prevent you from marrying this girl
    with no legitimate Islamic reason. If there is a reason, he should explain it to you so
    that you will understand what is going on. 
Our advice to you is this: if you can possibly change your mind and
    find another girl to marry, in order to please your father, maintain family unity and
    avoid division, then do so.
But you may find that you cannot do that, because your heart is
    attached to this girl, and you cannot bear the thought of marrying anyone else. You may
    also be afraid that if you choose another girl, your father might object to that marriage
    too, because some parents may try to force their son to marry a relative, or a woman whose
    qualities the father likes but the son does not. Some parents may feel jealousy or envy
    even towards their own children, so they prevent them from doing what they want to do. If
    this is the case, then there is no sin on you if you marry her, even if your father
    objects. Perhaps after you are married, your father may change his mind. We ask Allaah to
    help you make the right choice.
