He died and left behind a wife, three sons and five daughters
Question

                My father died and left us 25 million riyals. He has a wife, three sons and five daughters. How should the estate be divided?.
Praise be to Allah.
    If a man dies and 
    leaves behind a wife, three sons and five daughters, and the heirs are 
    limited to these people, then his estate is to be divided as follows: 

    The wife gets one 
    eighth, because there are descendants of the deceased. Allah, may He be 
    exalted, says (interpretation of the meaning):

    “but if you 
    leave a child, they [wives] get an eighth of that which you leave after 
    payment of legacies that you may have bequeathed or debts”

    [an-Nisa’ 4:12]. 

    The male and 
    female children get the rest, with each male getting the share of two 
    females, because Allah, may He be exalted, says (interpretation of the 
    meaning):

    “Allah commands 
    you as regards your children’s (inheritance); to the male, a portion equal 
    to that of two females”

    [an-Nisa’ 4:11]. 

    So the common 
    denominator in this issue is eight. So the wife gets one eighth, which is 
    one share. The remaining seven shares cannot to be divided according to the 
    number of children. The correct way is to divide it into 88 shares, of which 
    the wife gets 11, each male gets 14 and each female gets 7. 

    The wife’s share = 
    the estate × 11 ÷ 88 

    = 25,000,000  × 11 
    ÷ 88 = 3,125,000 

    The share of each 
    male = the estate × 14 ÷ 88

    = 25,000,000 × 14 
    ÷ 88 = 3,977,272.70 

    The share of each 
    female = the estate × 7 ÷ 88  

    = 25,000,000 × 7 ÷ 
    88 = 1,988,636.30 

    And Allah knows best.
