Her mother wants her to marry one suitor, but her father thinks that he is not suitable; what should she do?
Question

                My Mum wants me to get married to someone who my Father thinks isnt good for me and as you know men are the head of the family and I want my dad to choose my life-partner than my mum so is this right?
Praise be to Allah.
    Allah, may He be 
    exalted, has given authority in the matter of marriage to the man, so it is 
    not permissible for a woman to arrange a marriage for herself or for anyone 
    else; rather her marriage must be arranged by a wali or guardian. Women have 
    nothing to do with guardianship in marriage; rather that is only for men, 
    and is basically for the father, who takes precedence over others in 
    arranging the marriages of his daughters. 

    Imam Abu Bakr 
    al-Qaffaal ash-Shaashi (may Allah have mercy on him) said: 

    The reason being – 
    and Allah knows best –that women have a natural inclination towards men and 
    they are not able to judge people well, and that could lead them to choose 
    one who is not an appropriate choice (for marriage),therefore Allah 
    entrusted the woman’s case, with regard to her marriage, to her father. If 
    the matter had been entrusted to her, there would be the fear that she might 
    marry someone who is not compatible with her.

    End quote from 
    Mahaasin ash-Sharee‘ah, 247. See also the answer to question no.
    2127 

    If the father has 
    the right to guardianship in the case of marriage, and the marriage contract 
    cannot be done without him, then it is only logical that his opinion should 
    take precedence in the matter of choosing a husband for his daughter, 
    especially when he in most cases will be better able to judge their 
    character, thus he will be able to find out about the suitor and reach the 
    right conclusion. 

    But that does not 
    mean that the mother has no say in choosing a husband for her daughter; 
    rather she should be consulted about the matter and her opinion should be 
    taken into consideration, because perhaps it may be correct and some things 
    may be apparent to her that are not apparent to her husband. 

    To sum up: 

    The basic 
    principle is that the father’s opinion and choice takes precedence over that 
    of the mother, but that does not mean that the mother’s opinion should be 
    ignored altogether; rather it should be taken into consideration so so that 
    she does not feel left out and to convince her of the father’s point of 
    view, and that he is responsible with regard to their daughter’s marriage. 
    Thus the choice is up to your father, especially if he is known to be of 
    sound reasoning, but he should not make her feel left out; rather he should 
    respect her opinion. 

    And Allah knows 
    best.
