He died and left behind a wife, a son and three daughters, then the wife died
Question

                A father died five years ago and he had divided his estate whilst he was still alive. Now, five years later, the children are thinking about their shares of the estate and now there is nothing left but a house. In the family now there are a son and three daughters; the wife died during this period. How should they divide the estate, this house?.
Praise be to Allah.If the estate that the 
    deceased left behind without dividing it is the house, and the heirs want to 
    divide it, then it depends: 
If the wife was the mother 
    of the children mentioned, then her share of the estate should be divided 
    among them, so the entire house should be divided between the son and the 
    three daughters, with the male getting a share equal to that of two females. 
    So the house should be divided into five shares, with each daughter getting 
    one share and the male getting two. 
So each daughter’s share = 
    the estate divided by 5. 
The male’s share = the 
    estate divided by 5 and multiplied by 2. 
If the wife was not their 
    mother, then her share, which was one-eighth, goes to her heirs, and the 
    rest of the house is to be divided among the children, with the male getting 
    a share equal to that of two females. 
In order to divide the 
    house among the heirs, it should be divided into forty equal parts, whether 
    by meters or by selling the house and dividing its price. 
The wife gets one-eighth, 
    which is five shares. 
Each daughter gets seven 
    shares. 
The son gets fourteen 
    shares. 
And Allaah knows best.
