He died and left behind a mother, a wife, a son and two daughters
Question

                I hope that you can answer my question in detail: how much does each person get of the inheritance?

My father died and left behind a mother, a wife, a son and two daughters. The value of his estate is 172, 679 riyals.
Praise be to Allah.
      If a man dies and leaves behind a mother, a wife, a son and 
      two daughters, and there are no other heirs apart from these, then the 
      estate is to be divided as follows: 

    The mother gets one-sixth, because there are offspring who 
    inherit. Allah says (interpretation of the meaning):

    “For parents, a sixth share of inheritance to each if the 
    deceased left children”

    [al-Nisa’ 4:11]. 

    The wife gets one-eighth, because Allah says (interpretation 
    of the meaning):

    “but if you leave a child, they get an eighth of that 
    which you leave”

    [al-Nisa’ 4:12]. 

    The rest goes to the children, with the male getting the 
    share of two females, because Allah, may He be exalted, 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]. 

    So the division of the estate is as follows: 

    The mother’s share is 28,779.80 

    The wife’s share is 21,584.80 

    The son’s share is 61,157.14 

    The share of each daughter is 30, 578.50 

    And Allah knows best.
