It is not permissible to pray against oneself
Question

                I am a girl who was born with a physical defect, which is that I do not have a uterus. My younger sister started her periods late and I was afraid that she would be like me, so I asked Allaah not to let me get married and to grant my sister her periods so that she would not be different from her friends and she would not go through what I went through. Is it permissible now that she has reached puberty, praise be to Allaah, to pray to Allaah for a righteous husband or will I be sinning if I do that?.
Praise be to Allah.It is permissible for you 
    to pray to Allaah to bless you with a righteous husband, and there is no sin 
    on you for that. You were wrong in offering the first du’aa’, because the 
    Prophet  (peace and blessings of Allaah be upon him) forbade praying 
    against oneself. 
Muslim (3014) narrated that 
    the Prophet  (peace and blessings of Allaah be upon him) said: “Do not 
    pray against yourselves, do not pray against your children, do not pray 
    against your wealth, lest that coincide with a time when Allaah is asked and 
    He answers your prayer.”  
And Muslim (920) narrated 
    that the Prophet  (peace and blessings of Allaah be upon him) said: “Do 
    not pray against yourselves, except for good things, for the angels say 
    Ameen to whatever you say.” 
And Muslim (6288) narrated 
    from Anas (may Allaah be pleased with him) that the Messenger of Allaah  
    (peace and blessings of Allaah be upon him) visited a Muslim man who had 
    grown weak like a chicken. The Messenger of Allaah  (peace and blessings 
    of Allaah be upon him) said to him: “Did you pray for anything or ask Him 
    for anything?” He said: Yes, I used to say: O Allaah, whatever punishment 
    You are going to give me in the Hereafter, give it to me in this world. The 
    Messenger of Allaah  (peace and blessings of Allaah be upon him) said: 
    “Subhaan Allaah! You cannot bear it. Why didn’t you say: O Allaah, give us 
    good in this world and good in the Hereafter, and protect us from the 
    torment of the Fire?” Then he prayed to Allaah for him, and He healed him.  
We ask Allaah to bless you 
    with a righteous husband. 
And Allaah knows best.
