Is it permissible to refuse a good Muslim for personal reasons?
Question

                Is it considered a sin to refuse to marry a good muslim man for personal reasons, i.e. doesn't like him?

What are the bad consequences of such an action, on a personal level and in general, if there are any?
Praise be to Allah.
    No, this is not considered to be a sin, because Islamic says 
    that personal conviction has its role to play in marriage. (A woman may not 
    like a man because of something in his appearance, and she is not sinning if 
    she refuses his offer of marriage), but if you fear that you may miss the 
    boat or that you may not receive a similar offer, then put your feelings 
    aside, use your common sense and hasten to get married. 

    From the answer of Shaykh Ibraaheem al-Khudayri. 

    If a woman follows her whims and desires by rejecting a man 
    who is religiously-committed and has a good attitude, she may be punished by 
    remaining a spinster (i.e., unmarried). 

    May Allaah bless our Prophet Muhammad.
