She died and left behind a daughter and a brother
Question

                A lady died who has an estate, and she has a daughter and son. What are the shares of each of them?.
Praise be to Allah.The daughter 
    gets half, because Allaah says (interpretation of the meaning): 
“Allaah 
    commands you as regards your children’s (inheritance): to the male, a 
    portion equal to that of two females; if (there are) only daughters, two or 
    more, their share is two-thirds of the inheritance; if only one, her 
    share is a half”
[al-Nisa’ 
    4:11]
The 
    questioner does not describe the brother’s situation. Is he a full brother 
    or a brother through the father only or through the mother only? If he is a 
    full brother or a brother through the father only, then he gets the rest of 
    the estate after the daughter takes her share (half). That is because the 
    Messenger  (peace and blessings of Allaah be upon him) said: “Give the 
    shares of inheritance to those who are entitled to them, and whatever is 
    left, it should go to the closest male relative (on the father’s side).” 
    Narrated by al-Bukhaari (6773), Muslim (1615). 
This brother 
    is the closest male relative to her, so he gets the rest after the daughter 
    takes her share. 
But if this 
    brother is a brother through the mother only, then the division of the 
    estate is different.  
The daughter 
    gets half, as stated above, and this brother through the mother does not get 
    a share, as he is not entitled to anything of the estate, because a brother 
    through the mother does not inherit anything if there are any children 
    (whether male or female), because Allaah says (interpretation of the 
    meaning): 
“If 
    the man or woman whose inheritance is in question has left neither 
    ascendants nor descendants, but has left a brother or a sister,” 
    – i.e., on the 
    mother’s side – “ each one of the two gets a sixth”
[al-Nisa’ 
    4:12]
So the 
    brother on the mother’s side does not inherit anything unless the deceased 
    left neither ascendants nor descendants (kalaalah). 
Kalaalah 
    means the one who has no father or son, i.e., he has no father or 
    grandfather, and no son or daughter. 
The scholars 
    are unanimously agreed that brothers on the mother’s side do not inherit 
    anything if there is one of the children of the deceased (whether male of 
    female). This was quoted by Ibn Qudaamah in al-Mughni (9/7). 
Based on 
    this, the daughter gets half, as mentioned above, then if there are any male 
    relatives such as paternal uncles and their sons, after the daughter takes 
    her share, the rest is given to the closest man among them. If there is no 
    one, then this wealth should be given to the daughter, who takes the whole 
    estate.
