His father does not agree to him marrying a girl who is two years older than him
Question

                I got to know a young man who is religiously committed and of good character on a course four years ago, but his father refuses to let us get married because I am two years older than him. I want to know what the Islamic view is on that, and what we can do.
Praise be to Allah.
    Firstly: 

    There is nothing wrong with a man marrying someone who is two 
    years older than him or more, if she is religiously committed and of good 
    character. The Prophet  (peace and blessings of Allaah be upon him) 
    married Khadeejah bint Khuwaylid (may Allaah be pleased with her) and she 
    was older than him. 

    But the father’s opinion should be borne in mind when 
    choosing a wife for his son, because of his right to be respected and 
    honoured, and because of his experience which the son does not have. But the 
    father’s agreement is not an essential condition of the marriage being 
    valid, unlike the woman whose marriage is dependent on her guardian’s 
    approval. 

    Secondly: 

    The son should try to convince his father and explain to him 
    how keen he is to marry you. If the father responds, then praise be to 
    Allaah, but if he insists on his attitude, then the son is caught between a 
    rock and a hard place: 

    1 – He can give up his own wishes and do what his father 
    wants. This is better for him in most cases, unless the father’s nature 
    indicates that he will never agree to anything for his son except that which 
    he chooses himself, which is not in accordance with the son’s wishes, such 
    as if he chooses someone from within the family or tribe who is not suited 
    to the son, or it seems that his objection is based on the woman’s religious 
    commitment and upright character. In that case the son will have no choice 
    but to go against him, because if he does not go against him today, he will 
    do so tomorrow. 

    2 – Or he can do what he wants and go against his father’s 
    wishes – assuming that he can afford to get married by himself. But this 
    should not be done, because it is going against the father and making him 
    angry, and there is the possibility of family ties being severed and enmity 
    being created, which would be harmful for the son and his children, and for 
    you too. The wise woman should not agree to such a marriage, except in cases 
    such as we have mentioned above, which is where the father’s way of choosing 
    a wife for his son usually goes against the son’s wishes and there is no 
    option but to go against him, because some fathers have their own tastes or 
    opinions that do not suit their sons. We advise fathers to allow their sons 
    the freedom to choose, because marriage is a lifelong commitment and a 
    person has the right to choose the person with whom he will share his life. 
    The father’s role is offer advice and guidance, not to force any choice, so 
    long as the son will choose someone suitable. 

    The son should try hard to convince his father. We ask Allaah 
    to help you to do all that is good. 

    And Allaah knows best.
