Her mother gave her brother a gift to the exclusion of his siblings. Is this gift permissible?
Question

                My father put the house which he built in my mother’s name, without giving her any money. My mother has put an apartment in my brother’s name, and all he did was some finishing work in it. She gave him a big store which my brother is benefiting from by renting it out, and she gave him a place to work underneath the stairs. She said that this was a gift for her son, and after my father died, she will not agree to give me any part of the house. She said that it is in her name and I have no right to it until after she dies. Please note that my father has not left behind anyone but me (a daughter), my brother and my mother. What does Islam say about this?.
Praise be to Allah.
    Firstly: 

    It is permissible for a husband to give his wife whatever he 
    wants of his wealth, and he does not have to be fair between her and his 
    children, but that is subject to the condition that he does not aim to harm 
    his heirs by doing that. 

    Allaah has enjoined upon fathers and mothers to be fair 
    towards their children in giving gifts. It is not permissible for them to 
    give to one and not the others. If they do that, they must either take back 
    what they gave, or give the rest something as well so as to be fair. 

    What your mother has done by giving an apartment, a store and 
    another place to your brother is something that is haraam. What she must do 
    is to treat you both fairly. 

    It was narrated from al-Nu’maan ibn Basheer (may Allaah be 
    pleased with him) that his father brought him to the Messenger of Allaah 
     (peace and blessings of Allaah be upon him) and said, “I have given 
    this son of mine a slave.” He said, “Have you given a similar gift to all of 
    your sons?” He said, “No.” He said, “Then take it back.” Narrated by 
    al-Bukhaari, 2446; Muslim, 1623. According to another version narrated by 
    al-Bukhaari (2587): “Fear Allaah and treat your children fairly.” He said: 
    So he went back and took back his gift. 

    In the answer to question no. 
    67652 we have stated that it is 
    obligatory for a mother to treat her children fairly in gift giving, and 
    that fairness in gift giving means that the male gets the share of two 
    females, because there is nothing more just than the shares allocated by 
    Allaah. 

    And Allaah knows best.
