He died and left behind a wife, children, brothers and sisters
Question

                How should the property of a Muslim be divided who had a wife, two daughters (under the age of 16), a son (eight years old), two unmarried sisters (over the age of 30) and three brothers who are married?.
Praise be to Allah.
      If a man dies leaving behind a wife, a son, two daughters, 
      and brothers and sisters, the estate is to be divided as follows: 

    The wife gets one-eighth, because there are children, as 
    Allah says (interpretation of the meaning): “their 
    (your wives) share is a fourth if you leave no child; but if you leave a 
    child, they get an eighth of that which you leave” [al-Nisa ‘4:12]. 

    The children (the son and two daughters) get the rest, with 
    the male taking the share of two females, because Allah 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” [al-Nisa’ 4:11]. 

    The brothers and sisters do not get anything, because they 
    are blocked by the presence of the son, according to the consensus of the 
    scholars. 

    When dividing the estate, it should be divided into 32 parts 
    of which the wife gets four, the son gets 14, and each of the daughters get 
    seven. 

    And Allah knows best.
